Do any of you use a pressure washer to clean your RV? Is it harsh on the finish and decals?
Driving in the rain at freeway speeds is much harsher than a pressure washer spray from 1 foot away.


I'll say not even close on this one.
That water is coming out at a lot more than 70 mph, lol.
Think about it, a 2500psi + pressure washer. Pretty much any model with a gas engine will peel your skin off with a narrow angle tip, instantly.
But you could drive with your head out the window in the rain and it'll just sting. (Wear glasses if yur gonna try this, lol)


Ive ridden motorcycles in the rain. Doing 30....40...50mph those droplets hurt!! I also have a gas pressure washer and use it all the time. From 1 foot away the blast is mostly air and mist. Very gentle and doesnt hurt.

I think it comes down to the mass of the water droplets.


Please don't let your lack of understanding of the definition of pressure or your own pressure washers malfunction lull you into thinking pressure washers aren't potentially dangerous tools.

Got that one right Grit Dog. You can do a whole pile of expensive damage in a hurry abusing a pressure washer. Says he who has a dog who thinks the pressure washer is wonderful on a hot day. The mist is so refreshing it appears.

Also had a weird cat that like the hose of the vacuum cleaner run over her. Must have been a de fleaing method.

Yes I use it all the time. I start with a bucket of soap,bleach,Ajax or Oxiclean and hot water on the roof with a long handle brush. Then power wash the roof and all the AC covers etc. It gets off all the mold and black streaks. Then do the sides. Just use common sense around decals clean at 90 degrees. I have the Zeps treatment on mine and even at 2 ins away it will not remove the Zeps let alone affect the FG or decals. I also use it to clean under the MH, grease of the front end and drive shaft fittings etc and dirt off of the frames and wheel wells. The one on sale is probably electric and 1500 psi or less, buy you will use it for cleaning other things also. We live in America so everyone thinks differently, some change oil every 3000 miles or yearly some feel more comfortable and go twice as long.

Can you adjust the psi on electric power washers so it's not as strong?

Yes you can change the pressure very easily. It is as simple as not holding the nozzle so close to the work. Another important trick is to always keep moving. Worst thing you can do with a powerful washer is to blast a stubborn bit of dirt without a sweeping motion. Get a scrubber to remove whatever won't come off easily with the washer.

I use an Ryobi electric pressure washer with a Ryobi foaming soap canister at the end of the wand on my 5th wheel. I use a foaming Car soap I bought at Wal-Mart as the Ryobi soap gets to be expensive. I coat the area I want to wash with the soap and then let it sit for awhile. This really helps on the front cap to help soften the bug guts there. I then use a long handle car brush that reaches all the way up. Then set the soap canister to water only and rinse. 5th wheel comes out looking great and never a high pressure that if used incorrectly could damage the decals etc.

I use this on my car, truck, lawn tractor and 5th wheel. The big benefit is dirty soap water never gets put on the vehicle.

After reading dlpllg's post, has anyone found a soap/ foam Cannon whatever that truly softens "normal" dirt and road grime enough that a normal 2500 psi pressure washer actually gets the vehicle 100% clean with no touch, no scrubbing?
I'd pay for that, just haven't found one yet I believe will work 100%.
Neighbor even bought the expensive chemical guys setup and foam a couple years ago. Said how good it was initially and then reality set back in and it doesn't actually do the job 100%. Back to rags, sponges and brushes...

The closest I found was from the Auto Geek, but then name escapes me.. I'll get it if interested

DPG here,

I tried foaming and letting it sit and then using the pressure washer to rinse with the appropriate nozzle and it didn't get it totally clean. Using the brush really made a difference. It wasn't that hard just kept moving the brush. No need to keep dipping it into the soap bucket as soap was already one RV. The trick is to let it sit and soften as much of the dirt as possible.
