Picked up my RV from my son's house, and it had been sprayed for months by his lawn sprinklers. He must have the hardest water in creation, because I could barely see the side mirror out the driver's side window. The crud almost turned the window into a mirror.
Spent an hour and a half tonight cleaning the windows with a special glass-cleaning product.
The bad news is that there is the same mineral scaling on the paint. I bought some Maguire's polishing compound ... so tomorrow I'm going to try to get the whole driver's side done. It's going to rain this weekend and SNOW on Monday. So time is limited.
Ain't it great to own an RV!
(sorry guys, didn't think to take pictures before I started cleaning).
