pressure washer

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.
