Pressure washer use on the side of Class A

[sempka]

Just bought a 2000 Holiday Rambler Admiral Ford Chassis and V-10 motor. Trying to get the unit clean is it OK to use a pressure washer on the side panels if I stay away from the seams?

Thanks

I friend did his HR. Loves it.

ask if he still loves it when it yellows and he has to scour the old off. that stuff is for floors and there is a big difference in using a floor buffer to apply/shine it and on the vertical side of a RV. as said I wouldn't use ZEP/red max myself as there are many other more appropriate products. as I recall, folks here have said that it needs three coats/applications which is 3 times the work. It was a fad when home depot/lowes was clearing it out at $5.00 for a 55 gallon drum or some such and I bought a bottle myself. after reading threads here on it,I did not use it myself other than applying a small amount to dull areas when I was getting it ready to sell. let the new owner mess with removing it.

one of the nozzles I have for my PW is very "gentle", as is the soap spraying one.

The big danger with pressure washers is blowing past the seals in windows, doors and slide outs.

So make sure you blast in such a way you do not, and as someone said, keep at least 12" away, use due care and caution, I've done it several times.

Ended up using a car wash soap and regular hose. Now I will wax it.

How dirty is your HR?
If it's oxidized, consider the Zep/Red Max Pro Process. It does a great job.

If you don't like the idea of floor was on your rig, after the prep work, use the car wax of your choice.

It did a nice job on our 96 Southwind.

I don't use a pressure washer on the Southwind.

Nothing works as well as a bucket of soapy water & a soft brush. Use automotive soap or boat soap. Dishwashing liquids strip any wax that may be on it.

Pressure washers are good for getting chunky bits off & wheels but to avoid damage to decals the wand has to be held a distance from the surface, effectively greatly reducing pressure on the surface.

After washing with the brush a pressure washer, at a safe distance, is great for the rinse off. For the blow dry, use a leaf blower. Don't want to exert oneself too much by using a chamois to dry you know.

Using a pressure washer is normally discouraged. Dishwashing liquid and a water hose with nozzle will do fine. Be careful, too much pressure can damage your trailer.

You don't say how much psi your washer has....I have a 2500 psi and its turned down to 1800 and I used do my rubber roof with it with no damage; BUT...I use a 40 degree nozzle and it doesn't come with 2 feet of any surface including decals. I haven't use it on RV for probably 3 years. Water and a nozzle from hose does just as good if not better than pressure washer IMO.

Thanks, I'll be careful.

Just remember, the finish on an RV is not like a car or truck.
I will use the pressure washer on ours, but more for rinsing, I use a long handle car wash brush and rinse with the pressure washer, keeping the high pressure spray well away from the surface and even further from any seams, openings and decals.
Generally I just use the garden hose and bucket , using any car wash soap.

Never get within 12" of the surface, should be OK, If you get too close the pressure will find a scratch and start blowing the paint off. ----- jellcoat, no problems
