pressure washer

I have been in RV parks where they allowed you to wash your own coach but only if you used a pressure washer (that's how much less water is required).
I have a very small Kartcher (1300?) with an adjustable wide fan to nearly pin point spray. Depending upon what you are wanting to do, this unit can do it. I use the "killer pin point" to clean my grill and I use the wide fan to rinse the coach and I use something between the 2 to flush my radiator. I don't think I could live without it!

I have a very odd pressure washer. It came with the rv, and I havent tried it out yet but it's odd.

It doesnt pressurize the water via pump, it relies on compressed air from the air tanks (I guess) on the rv itself. The handle has both a water input and an air input.

I'm kind of curious as to how effective it is, but cant wash the rv in this park.

I have been using pressure washers on fivers and MH for over a decade. I have a high pressure gas powered one at home. I use the 25 degree tip and stand back about 10'. I get closer for tires, wheels and rear mud flap. Never had any issues except some water around slide seals. I just try not to point the wand directly at the seams. I hand wash the top with a mop and bucket.

I also carry an electric power washer for use on the road. Does a pretty good job if the bus is not really dirty.

Yes, I use a electric Black Cat pressure washer that I bought while traveling through Oregon, and it works really good. It does not have the super power of a commercial pressure washer, but in my opinion just right for washing a dirty coach. I also use it for spraying and washing the radiator and the CAC. You get different nozzles with the pump. Some for hard spray and some for milder spraying.

I have the fiberglass roof, so it works really good on that type of roof. For the sides I spray it with a mild non detergent dish soap, then I spray it with soft water and the last spray is with a water and Blue Coral liquid solution mixer. I still wipe it dry after all of the spraying. But I only use it when the coach has been through some rough weather, other wise I just dry wash my coach with THE SOLUTION.

Thanks for the replies. Doesn't sound like I can use the mh to justify it. Oh well.

Who needs to justify what they buy? I say, if it makes you happy, buy it. Life's too short, and it has an expiration date.

I use mine all the time on the roof and all the caulked areas. I figure that if it lifts the caulk and leaks that would be a good test and a good thing to fix in the driveway rather than in a rain storm on the road. In 9 years of using it I have never opened up a leak or cut through the rubber. Once a year I also use it underneath the MH to remove dirt and grease buildup. Just be reasonable with how close you hold it. They are all different in PSI.

Well Gang,
This is all about COMMON SENSE! It doesn't take a rocket scientist to judge just how much pressure is needed for a given job or, just how close or far away from a surface you need to be to accomplish a purpose. You can use a 3000 psi pressure washer on any surface you'd like as long as you don't get close enough to do damage. It's all about accomplishing your goal without issues. As you can see and read here, some do it and some are really advocates against it.

And yes, just about 100% of the detail crews, at any campground/RV park that allows them, use a PRESSURE WASHER, with few exceptions. If you watch them, they don't get close to rubber seals in windows, graphics, and anything else that can possibly either let water infiltrate, or be damaged by the higher pressure. The MAIN reason that they use them is water control. The can do a good job of rinsing, getting all the soap solution off without creating the Mississippi river in the middle of the camp ground.

And that's the primary reason that most campgrounds will NOT allow for RV owners to wash their own rig. Many of you are smart enough to use a nozzle that controls "on-off" to keep from flooding the entire campground but, some, will just let the hose flow while they soap down their machine.

Anyway, a pressure washer is perfectly safe, as long as the user is wise in its use.

I have used them. They clean up the roof and wheels/undercarriage good but be very careful around decals and caulking.
