What is RV Slide Lubricant?

As you travel through different terrains, your RV gathers dust, dirt, and several other elements. Due to the different environmental factors, and the changing weather and temperature, dirt, snow, rust, and dust particles start accumulating on the slide-out. The build-up of these elements then causes the slide-out to get stuck, and this is where an RV slide lubricant comes in.

A specially formulated product that helps keep your RV's retracting system in shape, an RV slide lubricant decreases the friction that's caused by a build-up of corrosion and dirt in the window. It also tackles debris and makes it easier for RVers to clean problematic areas.

How Often Should You Lubricate Your Slide-Outs?

Experts suggest that it is always) a good idea to stay on top of maintenance when it comes to an RV or other vehicles. And this includes proper lubrication.

The answer to this question does depend on the model of the RV slide-out. Always remember to consult the vehicle's manual to learn about the recommended number of times you should lubricate the slide-out. Certain experts say you shouldn't do so more than once every eight weeks.

However, lubrication also depends on the type of environment the RV will be facing. You will need to apply more if you are going to travel in areas with a lot of moisture, cold, or snow. Going through areas with high heat would also make for a more enjoyable experience if the RV slide-outs are lubricated.

Just remember to have control and not go overboard with the process. Too much is going to cause more harm than good in the long run.

Are All Lubricants The Same?

When you go looking one, you will see a lot of options for you to choose from. Now, wondering whether or not all are the same is a valid question to have. However, upon further research, you will see that no, not all lubricants are the same.

Depending on the kind you choose you will notice some have a dry consistency while some are wetter. Furthermore, some have petroleum added while some make use of silicone.

Some types available in the market start as liquid vapors (in the form of a liquid spray) and then turn into a greasy protective layer on the area they have been applied to. Particular lubes are fluids and have to be applied with a cloth instead of being sprayed.

How to Choose Slide Lubricant For Your RV

When looking for a lubricant for your RV, should you simply go ahead and pick the first you see? No, you need to do proper research to find the perfect option. By doing so you will be able to extend the longevity of your vehicle, which is something we all want, right?

Here are a few essential factors you should keep in mind when buying:

Level of Lubrication

Obviously, you are purchasing this type of product for lubrication purposes. That is why it is crucial to see the extent of lubrication the said item is able to provide you with.

Level of Protection

A reliable option is one which protects the area of application. Ensure the lubricant you buy protects the surface from rust and corrosion. It should be able to repel water and resist heat.

Ease of Use

The lubricant should be easy to use. Does it come in a spray can or will you have to first apply it to a piece of cloth and then to the intended surface?

Is it Runny?

No one appreciates an option which drips or is runny after application. Such an option can cause a lot of mess. So, make sure the lubricant you select isn’t runny and doesn’t drip.

Cautious Considerations to Keep in Mind

Selecting the best RV slide lubricant depends on several different factors. To ensure you make the right decision, here are some considerations to keep in mind:

Lubrication Quantity

The amount of lubricant needed to be sprayed differs with every situation and depends on the efficiency of the lubricant, along with the seriousness of the issue. When selecting the right quantity, make sure you consider the amount that would be needed in the lubrication process, the frequency of the process, and the amount needed to maintain the slide-outs condition.

Since most slide-out mechanisms require regular lubricant applications, it's advisable to buy the product in bulk.

Lubrication Level 

Simply put, the lubrication level refers to the efficiency of the product. All slide-out lubricants have different lubrication levels suited for solving different problems. Mild lubricants are suitable for average and mild lubricant problems, whereas heavier lubricants are ideal for solving long-existing problems.

Identify the type of situation you're in regards to window lubrication, and then decide the kind of lubrication power that will best suit your requirements.

If you're on a budget and have a small lubrication issue, then it's better to purchase a mild slide-out lubricant, as it's cheaper than a stronger one. However, if you have a longstanding problem, then it's advisable to buy a strong lubricant, and consider it an investment towards future travels.

How to Lube Your RV Slide-Outs

Knowing the proper way to lube an RV's slide-out is essential if you wish to experience the full benefits of the lubricant you will be using. A lubricant won't be much help to you if you aren't able to use it properly. So, let's go over some of the steps you should keep in mind to properly lube an RV's slide-outs.

1. The first step is to pull out the slide-out. Only by having the slide-out fully extended will you be able to lube the required surfaces for efficient functioning.

2. Some of the most essential parts of the slide-out, which needs to be lubricated, are the rubber seals. You need to protect them from cracking or prematurely decaying.

3. Simply grab your lubricant and spray the rubber seals. You will need to keep in mind that you need to cover all of the rubber seals (from top to bottom).

4. The same goes for the gears, sliders, and other metal parts of the slide-out gear.

5. You can either go for a spray can or you can apply the lubricant to a piece of cloth and then use the fabric on the rubber seals.

6. Remember not to go overboard with the lubricant. A single application on the rubber seals and slide-out gears should be enough.
