    Default Check Out the Professional Car Washes

    I've had problems with sprinkler systems and mineral deposits from an automobile standpoint. I've used a local professional car wash which uses a vinegar solution and if you know what your doing you can do it yourself. The rust color may be from iron deposits and perhaps your local company may know the solution (pardon the pun). The next step is to redirect the sprinkler.

    White vinegar is good for removing waterspots....I've used it on painted surfaces and windows. If that doesn't work, I'll bet that a mild polishing compound would remove the stain. 3M makes a good hand polish called Finesse, it's made for hulls. You can find it in the marine section at Walmarts. Let us know how you make out.

    I have used this stuff called ZAP on my boat...and it takes care of the stains and other spots on the hull. try is in a hidden area first to test it. good luck.

    I have always used the fiberglas version of a product called Zing. Works great on waterline marks as well.
