Hey there, let’s talk RV roof cleaners

Well, folks, after 10+ years of working on RVs, I’ve seen just about every roof type out there. I’ve also seen what happens when you use the wrong cleaner. Trust me, you don’t want a leaky roof ruining your next trip. So, let’s chat about what’s safe to use up top – and what to steer clear of. First things first, what kind of roof do you have?

What’s your RV roof made of?

Most RVs these days have rubber roofs. You’ve got EPDM, which is tough and handles UV rays well, and TPO, which reflects heat better. Both are pretty common. Then there’s fiberglass – strong, waterproof, but not as popular because it costs more. And some of you might have a metal roof, like aluminum or steel. They’re sturdy but rare, and boy, can they make a racket in the rain. Knowing your roof type is key before you grab a cleaner.

Safe cleaners for your roof

If you’ve got a rubber roof, stick to stuff made for it. I’ve had good luck with Bio-Kleen RV Roof Cleaner. Here is an handy article detailing how to clean your RV roof using Bio-Kleen RV Roof Cleaner.

Simple Green All-Purpose works too. Dicor Rubber Roof Cleaner is another solid pick, and Thetford’s Premium RV Rubber Roof Cleaner & Conditioner does the job nicely. These won’t hurt the rubber – they just clean it up.

For fiberglass roofs, keep it simple. A little dish soap does wonders. There’s also a Dicor Fiberglass Clean & Prep that’s gentle enough to use without worry. Metal roofs? Dawn dish soap is my go-to. You can find RV aluminum cleaners too. They’ll keep the surface shiny without eating it away.

Cleaners to avoid – and why

Now, here’s where folks get into trouble. On rubber roofs, stay away from petroleum distillates like kerosene. They’ll dissolve that membrane faster than you can say “leak.” Harsh abrasives? Nope – they scratch it up. Citric cleaners, like those lemony ones, aren’t good either – they’ll damage the rubber over time by slowly seeping through and dissolving the glue that keeps your roof membrane in place.

Fiberglass is a bit fussier. Don’t use anything harsh or abrasive. Scratches can let water get in, and that’s a headache you don’t need. Metal roofs can’t handle strong acids or bases – think toilet bowl cleaners or oven cleaners. Chlorine stuff, like bleach, is a no-go too. They’ll corrode the metal, and rust isn’t far behind.

A little advice from experience

I’ve seen folks try to save a buck with the wrong cleaner. Next thing you know, they’re patching leaks or replacing seals. It’s not worth it. Pick the right stuff, and your roof will thank you. Clean it every few months – especially rubber ones – and check for cracks while you’re up there. Keeps things running smooth for those long hauls.
