Cleaning water line scum off of a fiberglass boat

[revpilot]

Just pulled the boat off the lake today, it's been in a slip since June and it's now 2 tone. I pulled it out once this Summer and frustrated myself with the pressure washer and soft scrub, there's got to be something to get that green scum off. I'm even willing to take it somewhere that dips them in a bleach pit or something if there is such a thing. Any advise?

BTW: Admin should give us a tracking# when we make a post so we can find it when we log on next, don't you think?

Muratic acid or Toliet bowl cleaner.. Mix it with some water. Only on the gel coat.

toilet bowl cleaner.. squirt it on, brush it around, let it sit a few minutes and rinse it off.. gone!!

We use a product called WonderFoam. Easier on the gelcoat than toiletbowl cleaner.

Thanks, but specify toilet cleaner. I tried Softscrub already because I thought that was a toilet cleaner. Maybe Henry's Lake scum is tougher

What's it called?

ummmmm... toilet duck, scrubbing bubbles, clorox toilet bowl cleaner..

not sure.. just go to the store, walk down the cleaner isle, find the toilet bowl cleaner, get the sh!t that has the nozzle on it that you squirt under the rim of the toilet ( ive used the gel in the past), squirt it on, lightly scrub it around, let it sit a few minutes and youll be set..

found this for you also:

Most hull cleaners are a solution of oxalic acid, and trust me, it will get your stains out with no scrubbing, and almost no work. The down side is that you are introducing a serious chemical into your environment. With that in mind, the best advice is to use it sparingly and in accordance to the instructions supplied with the product. The use of gloves is recommended, but what I do is apply it using a spray bottle. Using a spray bottle allows you to avoid skin contact with the acid. You simply coat the stained area and rinse well with fresh water. Rinse liberally, because the added water will help dilute the solution and make the run-off less of a concern. A good product that I have used is called "Star brite" hull cleaner. Hull cleaners like this would be in the same category as toilet bowl cleaners, and I have known some people who have used toilet bowl cleaners and muratic acid with similar results. Oxalic acid penetrates the gel-coat pores and all stains disappear, period.

Oxalic acid is the main ingredient in products like deck cleaner, wood brightener and other such products made for removing stains and dirt from wood. I wonder if they would also work on the boat?????

Now you're talking my language, If it's nasty to touch I'll let the worthless schmucks rinse it off at the counties mandatory boat wash station.

I had the same problem after pulling my boat out for the season. I found this system to work very well. Mix 50/50 of Lysol toilet bowl cleaner and Hydrogen Peroxide. I apply it using a soft brush with a handle, and with just a little scrubbing and rinsing it's clean as new.

Here's what I tried:

Bleach, Vim, Ajax, Toilet Duck, Pressure Washer, Boiling hot soap and water, a lot I mean A LOT of elbow grease and finally i gave in and went to the marine section of Canadian Tire to see if there was anything. Simoniz Boat Bottom Cleaner took the stains off with no effort whatsoever, just use gloves and I got a cheap sponge mop to get underneath without crawlin around.

Oxacylic acid will also clean out the dish washer or other rust stained
appliances or fixtures.
Don't ask How I know

I've heard that a solution of Vinegar and water will keep it off. Not sure if it will work after it's caked on like you have but I've been told to keep a bottle in my boat and spray it down after a day on the water and it keeps the scum off.
