What's the best cleaner

[bigriverdog]

I just bought a boat and it has been in a nasty lake for a couple of months. It has very hard water stains on the cav plates and hull. I have tried Ducky, Simple Green, and others with only moderate help. Anybody out there have a secret product or solution. It has to be safe for anodized plates, chrome and fiberglass. Any help would be great. I don't normally deal with this because my boats never stay in the water more than a few days.

Straight vinegar or "Gel Gloss" spray. I believe Home Depot now arries the Gel Gloss...Good Luck, Mike

Try some CLR.
It's made for cleaning calcium deposits and such in faucets and showers. Should cut the gunk without damaging the finish.

thanks guys, I wanted to use CLR but was afraid it would hurt the anodized finish. Have you ever tried it?

Flitz polish. You can get it in many cutlery stores and on line. That is all I use on my pollished aluminum and it is also good for fiberglass. Good luck.

Never tried the CLR on anodized stuff, but I have used it on cheapo brass plated bathroom hardware with no ill effects.
