RE: water stains
At an RV show my wife bought a product called Simple Clean. The product worked great removing new water stains in my old motorhome. After starting off dabbing, gentle rubbing, etc. I found the most effective way to get the tough stains out was to spray on the product, work it in with a scrub brush and suck the area dry with my shop vac. The product is sold by John & Sally James Enterprises Inc. The phone number on the literature in 352-685-3816, the web site is
www.simpleclean.org. I have no commercial interest, only a customer.
