Posts: 75 | I have a boat on a lift at a lake that is pretty dark with tannins. Over the course of the last couple of years the bottom portion of the hull has picked up a brown stain from the water. It is an aluminum boat with a painted hull. Any suggestions on what to use to remove this? Also, any product that I could use while the boat is on the lift that would not be harmful to the lake? Thanks. | ||

Posts: 20180 Location: oswego, il | check out simple green. I have cleaned it from my boats using it I believe its environment friendly, doubt a fish could live in it but maybe there are others more friendly. | ||

Location: 31 | Todd, you might just be stuck with it like me. I had the same problem on a small portion of white that sits below the waterline toward the rear of my fiberglass boat (the bottom is black). I tried everything like you and then even had a guy try to buff it out, it was better but still there and we concluded that the brown water somehow permeated the gelcoat surface. | ||

Posts: 3472 Location: Elk River, Minnesota | Hiya, That stain is probably etched in the paint as tannic stained water comes from tannic acid, which in many cases is due to swampy areas connected and/or surrounding a lake structure. Not sure how how you could remove it, but I wonder if you did work a bit with wet sanding the area, then follow up with a rubbing compound, polishing compound, then a polish and wax, you might be able to get it done. This is assuming the paint is an automotive paint/clearcoat Steve | ||

Location: Minneapolis, MN | I have used a cream product that is designed to remove this type of residue on the hull of my fiberglass boats. I imagine it would work similar on painted surfaces. http://protecproducts.com/index.php/home-page-products/nu-paint-moi... | ||

Meguiars hard water spot remover is liquid gold. It removed the yellowish tint under the water line of my white fiberglass boat and looks good as new... Works in seconds. You just spray on an area, let sit for 20 seconds and wipe off with a cloth. Could probably do it on your lift assuming it can lift your boat out of the water. | |||

Posts: 403 Location: Lakeville, MN | I recently picked up a project boat, it has horrible water line stains, spent the last 5 years in tonka.. anyway they are very hard and crusty and don't come off, any suggestions? It's an aluminum hull Edited by genesisperformance 7/13/2013 1:58 PM Attachments ---------------- IMG_20130713_135849.jpg (103KB - 200 downloads) | ||

Posts: 47 | Muriatic acid will remove the scum line, no matter how long the boat sat in the water. May need two applications for heavy / thick scum line. Best used on a day with a nice breeze and using a mask is not a bad idea either. Also use thick rubber gloves, if you get some on your skin spray with water. I used to take a milk jug and cut the top off, leaving the handle on. Pour some mauritic acid in the jug and use a 4 inch disposable paint brush. Work in small 3-4 foot sections. Dip the paint brush in the acid and paint it on the scum line / small section. The scum will bubble up. Wait 20-30 seconds and spray it off with the hose. The hull will look like new when your done. I never had a problem with an aluminum hull or the transducers, but be careful around anything plastic. Post the before and after pictures. | ||

Posts: 1 | I used the JVC cleaner on a Alumacraft to get the brown stain off,it worked GREAT ! I saw it on Midwest Outdoors,it looked almost to easy but it does what they say. We got it at Irv's in Tomahawk.Not sure how it would work on glass. Its a must have on a Flowage. | ||

Location: 31 | genesisperformance - 7/13/2013 1:56 PM I recently picked up a project boat, it has horrible water line stains, spent the last 5 years in tonka.. anyway they are very hard and crusty and don't come off, any suggestions? It's an aluminum hull When I was a lad I worked at a marina and because I was on lowest rung of the ladder I got the pleasure of the muriatic acid treatment. That stuff is almost as nasty as battery acid to work with, but agree that is the best way to attack that scum line. We used to put the acid in a trigger spray bottle and then power wash it off after a few minutes, I think I even waited longer than that sometimes but obviously do some research (I was a kid and it wasn't my boat:)). FYI, No matter how many times I would apply the acid sometimes there would always be a lingering brown shadow. I would like to see some before and after pictures too. | ||

Posts: 403 Location: Lakeville, MN | I thought I would post a quick picture, I finally have time to acid bath the boat, here's literally 5 min with of dabbing with an old brush. This stuff is pretty nasty though, fumes are annoying the cuts on my arms from working on my wifes car the other night, bundle up and wear a respirator if you plan to use it.

Posts: 1168 | Something not as harsh on the human senses to try is a product called Grid-10. It is an acidic cleaner used in milk houses and does the same thing but is much easier on your skin, nose, eyes, etc. You would want to make sure and give any metal a good rinse after using it because of the acid factor. Heck of an all around cleaner as well... A gallon of that stuff goes a long, long ways and can be used to clean sinks, showers, and a bunch of different tough stains to get out. You could use it to wash heavily soiled clothes but you'd only need a drop or two for a full load as it is pretty concentrated. | ||
