Whats the best stuff for cleaning stained ugly bottoms??

There are several hull cleaners out there, I like the stuff from West Marine.

You can easily get it at Home Depot $9 gallon. Literally spray it on with a bug sprayer and come back 5 minutes later and hit it with a hose.

Perfectly white and 10x cheaper than any marine product....

on off acid works great, but sucks to work with it. Muriatic acid will do it also. Neither are very good for your boat.

Used muratic and or on/off for 25plus years and never had a problem.

ON OFF is the best in my book

99% sure the Goof Off product is the same chemicals as On/Off. It smells exactly the same.

I was at my marina one evening and 6 boats were being detailed all of them were using this stuff. I picked some up, sprayed my hull and was very happy. My stainless Lathem steering hardware looks brand new!

I used toliet bowl cleaner (muriatic acid) last fall in a sprayer. Be careful with your driveway as it will stain the concrete. I also was careful with the drive and trailer and kept it wet/washed off of those.

Another product called Mary/Kate hull cleaner. Works great. As soon as it touches water it's dead. I wipe whole hull and the hose dry.
