How to fix sticky RV windows

By Gail Marsh
If you’ve been RVing for a while, you might have heard a sticky RV window’s shiver-inducing screech or squeal. I’m talking about windows that refuse to slide, latch smoothly, or open easily. Here are some ways to get your RV windows working smoothly again—whether they slide, use a latch, or are emergency push-out windows.

Squeaky or stiff sliding windows

Sliding RV windows are convenient but, after a while, they can begin to squeak or become difficult to open and close. Dust, dirt, and travel road grime can be the culprits. Here’s how to get them sliding smoothly again:

• Clean the tracks. Over time, dirt and debris get trapped in the window tracks. Start by vacuuming or wiping out the track with a damp cloth. For stubborn grime, use a small brush (like this one or an old toothbrush) to scrub it clean.

• Lubricate. Once the track is clean, add a lubricant. Silicone spray is a great option—it won’t attract dust like some greasier lubricants will. Spray a little on a cloth and wipe down the track of the window where it slides. You can also use a dry lubricant specifically made for RV windows like this, if you prefer.

Improving latch windows

Latch windows are often found in RVs. Over time, the latch might get stiff, and the window won’t open or close smoothly. Here are some things to try:

• Tighten or adjust the latch. If the latch feels loose or too tight, check the screws and adjust them. Tightening or loosening the latch (even slightly) can improve functionality.

• Use graphite lubricant. Graphite lubricant is great for latches. Apply a little to the mechanism—this will help it operate more smoothly without attracting dirt.

• Inspect seals. Sometimes the problem isn’t with the latch itself, but with the window’s seals. If the seals have deteriorated or are sticking, it can make the window difficult to operate. Clean the seals with mild soap (like Dawn dish detergent) and water, then apply a rubber conditioner like this one to keep them flexible.

Stuck emergency exit windows

Emergency exit windows are an important safety feature in RVs. They typically push out from the bottom in case you need to make a quick escape. The last thing you want is for this window to be stuck in an emergency. Here’s how to make sure it opens easily when you need it:

• Test regularly. Make it a habit to test the emergency exit window every few months to ensure it opens smoothly. If you rarely use it, dirt, grime, or even rust can cause it to stick.

• Lubricate the hinges. If your emergency window pushes out with hinges at the top, check the hinges for rust or debris. Use a rust remover, if necessary, and then apply a little lubricant. Again, silicone spray works well here.

• Check the seal. Like other windows, emergency windows have a rubber seal around them to keep out the elements. Over time, these seals can dry out, making the window stick. Clean the seals with soap and water. Let them dry completely. Then apply a rubber conditioner to prevent the seals from cracking and sticking.

Bonus tip: The wind or an accidental bump can cause your RV emergency window to close when you want them to remain open. You can avoid this with a simple hack. Take a wooden clothespin apart. Take the half without the wire and slip it between the red latch and window frame. The clothespin will keep the window braced open and can be easily removed to close the window.

Maintenance is key

The key to avoiding sticky windows in your RV is regular maintenance. A little bit of cleaning and lubricating now and then will go a long way to keep your windows working like they should. Whether it’s a squeaky slider, a latch that’s hard to open, or a stuck emergency window, these fixes should get things moving again. Happy RVing!
