I don't recommend using it at all. The high pressure can force water into the seams and joints anyplace that might have a gap or weak spot in the sealant, resulting in water in the wall cavity and insulation. I'd stick to the regular pressure of a garden hose.

I use a bucket of water with Dawn or Palmolive dish washing soap and a long handled, soft bristle, RV brush. Garden hose with spray nozzle on the end.

I have a power washer I use for lots of things but I would never use it on any RV. I "hand wash" ( microfibre cleaning mitt on a extendable pole ) using "RV/Auto wash soap" mixed in a bucket of water. And just a gentle mist of rinsing with a hose end nozzle.

I understand the above cautions, although I'm less familiar with AS than anyone here, hoping to buy our first soon. But the biggest issue to give thought to is the stream concentration, adjustment, of the nozzle.

I bought a simple electric pressure washer for $100 from Lowes reluctantly several years back. Didn't have high expectations but wasn't interested in the larger gasoline run engines for my needs either. What an incredible cleaning tool it has become!

We have big wrap around porches and I use it for cleaning the porches and handrails primarily. Also, concrete, wasp nest up high on house/garage, house windows, etc. but the main issue is not over doing it with the nozzle.

Or backing up of course accomplishing similar end result, less concentrated water spray. Be careful is my suggestion and practice using your new pressure washer on a less valuable surface first.

Whatever you do, don't put a concentrated spray on your sidewalk. Not unless you plan on spending remainder of the day making the rest of the sidewalk just as clean. Don't ask. Hah.


Shop Greenworks 1,600-PSI 1.2-GPM Cold Water Electric Pressure Washer at Lowes.com

Well, years ago I was warned on this forum not to use a power washer on our Airstream. Despite that, I have been using one for 13 years on it without a single problem. Mine isn't the most powerful of machines and I do use common sense (uncommon sense?) regarding concentrating the spray on areas like window frames. I do not rely on the washer to get the trailer completely clean, rather wipe it down afterwards with damp microfiber cloths.

Maybe I should also mention that our Airstream has very, very little filiform corrosion. That surely has nothing to do with the power washer, but I thought I should mention it before that warning comes up.

I used a power washer once. When I got the AS it had been in a barn for 3 or 4 years and had barn "dirt" in all the nooks and crannies. I kept the tip a minimum of 24" from the surface to flush out what couldn't be cleaned any other way. Worked out fine, but you have to be careful.

No pressure on rivets or seams or decals!

Keep distance as mentions... Using a good marine or auto soap but mild batch of Dawn works really well, follow with a auto type that has shiny stuff made into it...

I use a soft Marine brush on a Marine grade extendable handle... No problems.

Of course we are "North" of the "wierd place"!!!

power washer

thanks for all the comments & advise on using the power washer.
seems my problem might have been washing while the a/s was sitting in the hot tx. sun! should have done it first thing in the morning or later in the day.

We are physically "North" of Austin... The "self-professed Wierd place". They sell bumper stickers.. "Keep Austin wierd"... True!

As for the "film"... I would try waxing an area...
