If you have heavy algae buildup or rust stains, you can't beat MaryKate's On & Off.

Beware, this stuff is insanely strong and will burn your lungs, skin, eyes, trailer, etc. Use long gloves and wipe it on with a sponge and hose it off. If you use a spray bottle make sure the boat is dry or you'll smoke up your neighborhood when it hits the moisture. Algae and rust stains will literally disappear before your eyes, though.

I think this is a critical step when using the acid type hull cleaners. I've been doing some testing for several seasons and it seems to me that the cleaners have a tendency to etch the gel coat surface slightly. Although the hull looks clean and stain free after use of these cleaners, the staining seems to come back very quickly in the dark colored water where my boat spends most of its life. This is in spite of the fact that the boat is on a lift a wiped down immediately after use. To avoid this, I've found buffing and waxing after a good rinse of the acid bath helps to slow the time it takes for the staining to re-occur. I've tried a number of products on several sections of the hull and had very good luck with Colinite cleaner/wax. Areas that haven't been buffed or have had other waxes applied seem to pick up the stains much more quickly.

Second on the Mary Kate's On-Off Hull cleaner. Build up just falls off. Have seen it take off bottom stains that hadn't been touched in years. Also second the re-wax after use. Seems to keep the hull cleaner longer.
Just be careful the stuff is nasty.

I used the 'works' toilet bowl cleaner this spring and wasnt to impressed with the results. However, a couple weeks ago I used 3m gelcoat restorer and holy smokes did it clean things up. I did it all by hand and the results were awesome, I couldnt imagine what it would do with a buffer. After that I followed it up with collinite wax. Great results.

Liquid from Home Depot.

Liquid tide. Install drain plug. Mix water and tide and drive around the block a few times.

I stapled a rag onto a stick & swapped away under the engine. Hot water helps cut the grease too.

Product called Zing , spray on rinse off, perfectly clean. No scrubbing
