We went to Lowes this morning and I noticed a car wash kit. It was actually an extendable wand with a large brush. Camping World sells the same thing but this had a much larger brush and is better made. I tried to find the item on the web, no luck. I tested it on our MH. It is about 12' high and I could get to everything except 6" from the top. It did a good job of getting off the road grime without any soap. It is easy to use for a fast wash down, only took about 20 minutes.
It also included a standard water hose sprayer except this attached to the end of the wand. I found it useful to spray off the undercarriage.
I don't know the price, lost receipt. The device was called "Orbit Car Wash Kit". It was in the section with mowers. I am not endorsing the product or Lowes. I just thought this would be helpful to fellow RVers.
Sounds interesting, funny what we find in unlikely places and better quality too. Myself I use a Webbster brush on a painters pole. The webbster dries fast and can also be used as a brush or broom. I have noticed that websters vary in price from store to store and from place to place in the store. In either Home Depot or Lowes last summer I seen webbsters in the cleaning dept for $8 or $10 , in the pool supplies the same one was $15. Jerry
