I have got some water spots that have been cooked onto my Mercury outboard. They have been building up for sometime from the previous owner.

What is the best way to remove (or try) these spots which have been baked into my black motor by hours of sunlight?

I have waxed the thing numerous times with no luck.  My next step was going to be a power buffer.  Any other tricks/formulas/solutions to try?

Thanks

Wax won't do anythinhg but put a coating over it and make it harder to get off.

You can try baking soda and water mix into a paste and try to rub it out.

Or use a commercial product like CLR (think yoyu can get at wally world) or I've heard of people using just plain Lemon juice.

My boat stays stored inside and I wipe it down every time out, so mine really aren't baked on....but....I use Duckie and it works well.
