CLR® (Calcium, Lime, Rust Remover) should work and wouldn't be harmful to the fiberglass... it works on plastic showerheads. You can find it in most grocery stores.

Vinegar will take off most calcium deposits.

Alf I thought our HARD water was when the prop blade on the boat hit the sandbar. http://www.fiberglassrv.com/board/st...default/40.gif

We like Lemi Shine. Makes work very easy.

It was designed for dishwashers, but if you read their website it talks about many other applications. Basically any where, where there is Hard water calcium deposits.

When I lived on the West Coast of Florida, the sandbar solution was to have a stainless steel prop because they would stand up to grinding on the sand much better than the aluminum ones. Then I went down to the Keys and saw wading birds too close to the boat and found out that coral trumps stainless...

Thanks for the reply...I tried CLR...worthless
Then a guy that works on fiberglass told me to use 3M, 401Q Imperial Wetordry paper A Wt....PERFECT...used it then added polish back on it.

Now on a more regulare basis i'll clean off the spots with my CLR then once it's gone I'll try what you suggested..Lemi Shine

Thanks again

Just a word of advice -- If you use abrasive stuf, like most polishes actually are (read label carefully; they make the surface shiny smooth by removing part of it), often then you risk marring the gelcoat. That's especially true if your use is confined to just one area and even more true if you use machinery....

I see a distinct correlation between friends who own/use electric polishers and early surface deterioration on cars and boats.
