The majority of RVs these days have slide outs, but many RVers neglect their slides, month after month. What can you do to take care of your slides for years to come, but without needing a qualified RV repair person on standby? Something that you may want to consider purchasing is RV slide out lubricant.
But what exactly is RV slide out lubricant, and how can you use it to your advantage? In this guide, we will go over everything you need to know about slide out lubricant, including the different types, as well as how to best apply it. We’ll also give you a comprehensive list of products to choose from, all backed by customer reviews and knowledge.
Let’s get started and learn all about RV slide out lubricants now!

Types of RV Slide Out Lubricant
There are a few different types of RV slide out lubricant, which may make the buying process a bit more complicated. However, we’re here to tell you all about the different types so that you can make an informed decision. Here are the most common types of RV slide out lubricant.
Petroleum or Silicone Based
One of the first decisions you should make when shopping for RV slide out lubricant is whether you want a petroleum or silicone based product. But what are the main differences between these two options, and is there anything you should consider if they happen to be very different?
Petroleum based slide out lubricant is often more affordable and readily available. However, it is important to note that petroleum degrades natural rubber pieces and can be drying over a long period of time. This process is the same thing that leads to a bubbling toilet, too. While many RV manufacturers don’t utilize rubber in their RV construction anymore, it’s difficult to determine whether your RV has natural or faux rubber in its components.
On the other hand, silicone is a bit more expensive but it doesn’t dry out rubber like petroleum does. Silicone lubricants also perform well under high temperatures, making silicone based slide out lube ideal for warmer months and four season use.
Whichever product you choose, you should have success when lubricating your RV slide outs. Both ingredients help you in successfully lubing a variety of components. However, it is important to weigh your budget against the cost of replacing parts in your RV slide out. It’s definitely something to consider!
Aerosol or Liquid?
Another factor to consider in your RV slide out lubricant choice is whether or not you want an aerosol based spray lubricant or a liquid lubricant. What’s the difference, you might be asking yourself? The primary difference is simply convenience.
An aerosol based lubricant shoots out from a can and onto the components of your RV slide out, while liquid based lubricant needs to be applied to a rag or cloth and then wiped onto your slide out components. This is a subtle difference, but it often makes a world of difference to RVers.
Many consumers prefer aerosol applications not only for its ease of use, but also because the product has added pressure behind it. This helps many RV owners reach difficult spots of their RV slide outs, while a liquid lubricant needs to be applied by hand. You may not be able to reach all of the places you need to when using a liquid lubricant.
Again, much like petroleum or silicone based RV slide out lubricant, you can’t go wrong with either option. They both work great, but it’s up to you which one is more convenient or easier to use for your lifestyle.
What to Consider in RV Slide Out Lubricant
There are many other things for you to consider in an RV slide out lubricant other than the type that you prefer. Let’s discuss all of the other factors that you should keep in mind before making your final purchase.
Type of Lubricant Needed
As I have already mentioned, the type of lubricant needed matters for your RV slide out. You can choose between a petroleum or silicone-based lubricant, as well as a liquid or aerosol type. All of these work well in an RV setting and are fairly indistinguishable, but you’ve already learned that there are some differences that may lead to your final decision.
For example, knowing that silicone-based lubricant works better in warm weather than petroleum-based lubricants may make a difference to those of you planning on camping in hot climates frequently. Choosing between an aerosol or liquid type of lubricant may also factor heavily into your final decision based on your lifestyle and overall convenience needs.
Cost of Lubricant
The overall cost of your RV slide out lubricant may affect your decision. This is because you may end up using more product than you expect to based on the amount of slide outs you have and the amount of product that you need to properly lubricate them.
However, the cost of slide out lubricants is usually negligible, especially when you consider how expensive it can be to repair RV slide outs. The average slide out lubricant ranges in price from $10 to over $25. However, you likely won’t spend more than $30 unless you are getting multiple containers as part of a bulk purchase.
Amount of Lubricant Needed
Speaking of bulk purchases, you should consider the amount of lubricant needed to fully lubricate all of your RV slide outs. Depending on how many you have, you may end up needing a few canisters of aerosol lubricant or liquid product.
However, it also depends on how frequently you use your slide out lubricant as well, and you may also need more if you haven’t lubricated your slide outs in some time. I highly recommend purchasing at least two cans before getting started on lubricating all of your slide outs- that way, you won’t run out right away!
Ease of Use
One of the final things you should consider when purchasing RV slide out lubricants is the ease of use of the product. It almost goes without saying that choosing an aerosol based lubricant is more convenient in just about every way compared to a liquid lubricant. However, you may have your own thoughts on this and might prefer to use a liquid version over an aerosol version.
How to Apply RV Slide Out Lubricant
While you may not be certain of what RV slide out lubricant you want at the moment, you should know how to apply it either way. Here is a helpful step by step guide of how to apply lubricant to your RV slides, mechanisms, and windows!
- Begin by lubricating your slide out gears and rails. These components are a necessary part of your RV and they often get squeaky or misaligned first. Spray or wipe some of your lubricant on these components while the slide out is fully extended. Move the slide in and out once more to fully distribute the product. A little goes a long way in this particular area of your slide out, so keep this in mind when lubricating! Plus, lubricating your gears and rails only needs to be done once or twice a year.
- Lubricate your RV slide out seal next. This is where you should avoid using petroleum lubricant, as it has a high chance of drying out your rubber seals. Instead, use a silicone or dry lubricant, and wipe down all of your seals thoroughly. This process should be repeated every couple months, and you may consider a lubricant that blocks harmful UV rays or inclement weather. Your slide out seals are very important, so taking care of them is a must!
- Finally, lubricate the windows on your slide out. This may seem like a silly step, given that it’s just a window, but you may want to use slide out lubricant on all of your RV windows twice a year. This helps them move and stay pliable so that you can let fresh air into your rig for years to come!
Why You Should Use RV Slide Out Lubricant
Curious about why you should be using RV slide out lubricant in the first place? Here are some of our top reasons why this product is a necessary one for just about any RV owner!
Maintains Your RV Slide Outs
The main advantage to using RV slide out lubricant is that it maintains your RV slide outs in a way that few other products can. Using lubricant regularly on your RV slides can help you in a variety of ways including:
- Prevents dust, dirt, and debris from sticking to your gears and slide out components
- Keeps all components functioning without friction or distress
- Helps your slide outs operate in multiple weather and temperature scenarios
- Prevents all slide out components from rusting or corroding
- Maintains your slide out seals, especially during times of harsh UV rays or moisture
No matter why you start using RV slide out lubricant in the first place, you can rest easy knowing that you have made a decision that extends the life of your RV slide outs. That’s a huge win in my book, and just about every RVer’s book!
Keeps Your RV Slide Out Quiet
Another huge benefit to using RV slide out lubricant is the fact that it should help keep your RV slide outs quiet. Many RVers are plagued by the notorious squeaky slide outs, or notice that their slides creak after a certain amount of time on the road. What can you do if you notice this happening?
Using slide-out lubricants every few months can help prevent any squeaking or creaking that occurs within the mechanisms of your slide out. By maintaining your RV slide outs regularly, you can avoid any annoying sounds or inopportune functions while on your camping trips.
You Can Use RV Slide Out Lubricant Elsewhere!
Depending on the type of RV slide out lubricant that you purchase, you can likely use it elsewhere in your RV. Many lubricants are fairly universal and can be used in a variety of settings. But where else might you want to use RV slide out lubricant, either in your RV or in your home?
You can use RV slide out lubricant to maintain all of your windows and doors inside of your RV, spraying the hinges twice a year or so. You can also use lubricant on a variety of other closures and hinges, such as those on your storage compartments and outdoor storage solutions. Plus, your RV awning likely needs lubrication from time to time as well!
You can even use RV slide out lubricants in a variety of locations throughout your residential home and your residential automobile. Just about anywhere that you need lubrication, you can use RV slide out lubricants as well. That’s why I highly recommend finding a brand and style of lubricants that you enjoy using and a variety of locations and applications.

You may find that it has a wide variety of uses, including ones that may surprise you!
3-IN-ONE makes this two pack so that you can maintain your entire RV slide out without needing to worry about leaving something behind. You can maintain your gears, tracks, and window seals using both of these convenient aerosol products. And both of these lubricants help create a waterproof and rust proof barrier on your slide out components!
The only negative point that people mention with this particular product is that it has a fairly high price tag for an RV slide out lubricant.

Easiest to Use: Slide-Out Dry Lube Protectant- Protect All
✅ Easy to use aerosol can is a generous size
✅ Prevents dirt, rust, and water from entering your slide out components
✅ Ideal for those of you who have time to let the product dry
❌ May be difficult to remove from fabrics or clothing
Looking for a simple and efficient product for use in a variety of locations, and not just on your RV slide outs? Check out this product from Thetford, a well-known name in the RV game. Protect All is designed with RV living in mind. But it comes in a convenient aerosol can that works well for both old pros and newbies to the RV world. Let’s talk more about it now.
Protect All is designed to cover all metal components of your RV slide out, including the gears, track, and arms. You can use it quickly and easily, as it dries into a light waxy coating. This waxy substance resists moisture and rust, as well as dirt, dust, salt, and other road debris. Your RV slide outs will continue to function for months to come, despite whatever road conditions you may face!
The 16 ounce aerosol can is a generous size, larger than the can from 3-IN-ONE. You easily spray whatever metal component you need to, and be sure to give it ample time to dry. This product also dries in a light brown or amber color, so be aware that it does not dry clear. However, this gives you a good indicator for just how long the lubricant lasts. The color will disappear over time.
This product is budget friendly, and many reviewers mention seeing fantastic results after following the product instructions carefully. However, some people mention this product as being difficult to remove from clothing and cloth tents or pop up trailer fabric, so keep this in mind when using this lubricant.
Best on a Budget: CRC Power Lube Industrial High Performance Lubricant
✅ Fair price point for budget friendly consumers
✅ Highly concentrated formula makes lubrication easy
✅ Pressurized industrial can helps you reach difficult spots
If budget is something you are concerned about, check out this CRC Power Lube. While this product is not designed specifically for RVs and RV slide outs, it doesn’t mean that you can’t still use it in this sort of application and beyond. Let’s talk more about this product now!
This high performance lubricant product is ideal when used on a variety of metal applications, including your slide out gears and tracks. Using only a limited amount of the products, you can achieve a smooth and easy transition when sliding your slide outs in and out on a daily basis.
The industrial formula of this product gives you protection from moisture and corrosion as well as dust and debris. While it sprays on wet, it dries well and prevents any buildup of any sort. This makes it ideal in an RV setting where you are constantly surrounded by nature and debris.
One of the main selling points of this product is the fact that it is highly pressurized, which means that the aerosol spray reaches deeper and farther than the average aerosol spray. This can be especially beneficial when used in an RV setting and on a variety of hard to reach gears or tracks.
The main complaint regarding this product is the fact that it only comes in an 11 ounce can. This is significantly smaller than a variety of products on our list. However, you may not notice the smaller can size when using the product. It is highly concentrated and powerful, which means you likely need to use less overall, especially compared with other products.
Best for Full Timers: WD-40 – 490224 Multi-Use Product
✅ Two pack means that you get more bang for your buck
✅ Easy to use straw and multiple spray options
✅ Prevents rust and moisture as well as grime and debris
❌ Not made specifically for RV slide outs, so may not work as well as other products
If you are a full-timer living in your RV as your main home, you may be searching for a product that you can use in a variety of locations. WD-40 is a commonly used lubricant that has many applications throughout the average household, and it can also be used on your RV slide out components!
Many people use WD-40 because of its ability to repel moisture, prevent rust and corrosion. It can also lubricate any metal components that you want. Not only does this product help lubricate your slide outs, it also cleans out any dirt, dust, or debris that may already be present on your slide out.
WD-40 also has a few different styles of streams as well as an easy-to-use dispensing straw. The straw may help you reach difficult locations or spots on your RV slide outs, including gears or tracks that are deep inside of the body of your RV. But that’s not all that WD-40 is useful for.
You can use WD-40 on a wide variety of other locations such as door locks and hinges, other metal components, and more. This is why this product may suit full-timers well, as you can use this lubricant frequently. The fact that you can use it for more things than just your slide outs may be appealing for those of you lacking in RV storage.
However, some reviews mention WD-40 not working well on RV slide outs. And it does not help maintain or protect your window seals. If you are having trouble with your metal components sticking or squeaking, WD-40 may do the trick. And you have a product that works well in other areas of your home!
Largest Size: Kwikee KwikLube Spray Lubricant
✅ Large can size makes it possible to lubricate all slide outs at once
✅ Aerosol grease penetrates deep and maintains your slides for months
✅ Affordable and easy to store
❌ May lead to some build up of dust and dirt
Not only is this lubricant from Kwikee designed for many RV applications. It comes in a large aerosol size perfect for multiple slide outs. If you have an RV with more than one slide out, you may be interested in purchasing a larger 16 ounce container full of lubricant. That way, you can get all of your slide outs done using a single can.
Designed to coat your RV slide-out components in a protective coating, this lubricant can be used on all metal parts of your slide out including gears and tracks. It helps prevent moisture from intruding on your delicate RV slide out system. And it can help prevent grime build up as well.
The aerosol design of this can makes it easy to use in a wide variety of locations, including your RV steps, windows, and door latches. You can trust that this lubricant works in many different seasons and weather scenarios as well. It has been tested to work in up to 400 degree Fahrenheit conditions.
However, this particular product dries greasier than other RV slide out lubricants, which may make dirt and dust build up on your components. Some reviews also mention the fact that they wish this nozzle was better for applying the product. However, you may not have the same issues.
Best for Rubber Seals: Thetford Premium RV Slide Out Rubber Seal Conditioner and Protectant
✅ Creates a barrier that protects against moisture and UV rays
✅ Easy to use aerosol makes applying easy
✅ Prevents your slide out rubber from fading and cracking
❌ Not designed to be used on the tracks or gears of your slide out
If you are looking for a reliable lubricant and protective spray for the rubber seals of your RV slide outs, check out this product from Thetford. Whether you are new to RVing or an old hat, you likely recognize the name Thetford from a variety of other RV products. Let’s talk more about this rubber seal conditioner now.
It is just as important to maintain the rubber seals of your RV slide outs when compared to the metal components. Many people focus on the tracks and gears of their slide outs and neglect the rubber seals completely, but these need just as much protection as the tracks do.
This product is designed to prevent fading, cracking, and breaking of all rubber seals found throughout your RV. These include the seals surrounding your slide outs as well as your doors and storage compartments. You can also use this in your RV Plumbing, such as the rubber seals of your toilet or black water tank.
Not only does this product give your RV slide outs a protective coating to prevent UV rays. It also creates a barrier that protects against moisture and dust as well. The aerosol can makes this product easy to distribute, and there’s no need to wipe up any excess moisture or lubricant.
The only drawback of this product is that you can’t use it on the tracks and gears of your RV slide out, as it is only designed to be used on the rubber seals. However, these components are equally important and should be treated with the same level of care as your gears and track.

This lubricant understands that your RV deals with a lot of dirt and debris when on the road. That’s why it forms a protective coating or barrier that helps prevent all dust and dirt from settling on to the delicate gears of your slide out. It is also designed to prevent moisture so that your RV components do not rust or corrode.
This product is designed to limit the amount of friction happening when your slide out moves in and out. This can help your slide out motor work at an optimum level so that it does not burn out or face any unnecessary strain. Plus, you can easily apply this lubricant using the aerosol can that it comes in.
In general, this product seems to work better than products they receive at RV shops or car dealerships. It works for months to come, when applied correctly and given ample time to dry. However, some people mention that the product may not dry completely. It could potentially lead to some amount of dust buildup on your RV, but not many people mention this being an actual issue.
Best Brand Name: Camco 41105 Slide Out Lube & Protectant
Besides Thetford, Camco has to be one of the biggest brands of RV equipment and utilities on the market today. They make a variety of items, including tank treatments, RV accessories, and, of course, slide out lubricant. Let’s talk about this product from Camco now.
This aerosol lubricant comes in a generous 15 ounce can which should cover multiple slide outs through the use of a single can. This product is designed as a protectant against rust and debris, as well as a lubricant for all of the metal components in your RV slide out.
This aerosol can comes with a detachable straw for applying the lubricant in hard to reach places, which happens frequently in slide outs. You can also expect this product to contain no chlorinated or fluorinated solvents. Additionally, it can take over 300 hours of salt and water exposure without causing rust or corrosion.
Many reviewers mention that this particular product from Camco has extremely similar ingredients as WD-40. This is something to consider, given that most WD-40 is far more affordable than RV branded products, including reasonably priced products from Camco. However, this slide out lubricant is made for RVs, which may make its performance better in the long run.
Four Season Use: 3-IN-ONE-120138-C RV Care Rubber Seal Conditioner
✅ Easy to apply using the applicator straw
✅ Silicone based product protects and coats evenly
✅ Perfect for UV ray and harsh weather protection
❌ Doesn’t lubricate the tracks of your RV slide outs
If you are looking for a fantastic rubber seal product that makes your slide outs perfect for four season use, check out this conditioner from 3-IN-ONE. Not only does this aerosol can have a unique application straw and two stream sizes- it can be used in a variety of locations throughout your RV. Let’s check this product out in more detail now.
This conditioner can be used to lubricate the mechanical parts of your slide outs, but it is ideally used to protect and coat your rubber seals against four season issues. Some of these issues can include UV ray damage, which is notorious for cracking, fading, and weakening your RV’s rubber seals.
Given that this product is a silicone based formula, you can expect it to work well in all seasons and extreme weather scenarios. So long as you let this product cure in an adequate amount of time, you can expect it to work in both freezing weather and hot summer months.
You can also use this product on a variety of other rubber seals, including the ones around your RV’s windows and doors. You may also find this conditioner useful for the rubber seals surrounding your storage boxes and beyond. It has a lot of uses, and can really help you maintain your RV slide outs from top to bottom.
However, this product isn’t technically designed to lubricate the metal tracks and gears of your slide out. You will likely need to purchase another product to totally complete the job. If you are seeking a product that helps protect against harsh UV rays however, you can’t go wrong with this option!
