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.
