Questions on finishing of aluminum pontoons
Q. (1) Is there a means of reducing or eliminating barnacle growth on my aluminum pontoon boat? De-fouling paint has been of very limited usefulness.
(2) I am told by the manufacturer that, with a proper zinc block, pontoons will not be adversely affected by salt water and that painting with de-fouling paint is not required. Do you understand this to be reliable information?Alvin B [last name deleted for privacy by Editor]

A. The manufacturer knows best, especially if a warranty is involved. Zinc anodes will be helpful towards reducing corrosion, but in my experience will do nothing to deter barnacles. But most anti-fouling paint is copper-based, which corrodes aluminum. I would not use anti-fouling paint on aluminum! "Regular" paint only, pressure wash the barnacles every chance you get, and get the boat of the water when you can.

Q. I would like to find out what would be the best cleaner and polish for pontoon boats! Is there anything to spray, like a clear coat on them, or will it last long enough in water? I'm open for suggestions, since I'm starting to clean pontoons, and house boats!

We have a pontoon boat which has been in the water for over a year without moving. I cleaned the pontoons with retail grade hull cleaner, which removed the marine growth but the aluminum is stained and is now grey / black color. What is the best product and method for restoring the aluminum?

Q. Hi, I'm a weekend boater and recently purchased a pontoon boat that has sat in water all winter. It has algae, grease and grime on the pontoons. What is the best way to clean them and with what. Once the pontoons dry the gunk on them is as hard as concrete.

A. Dissolving this stuff later is one thing, Chris, but pressure washing them before they dry would be the best first step. Fresh barnacles are not too hard to remove; but dried ones are much harder :-)

A. I have the answer to the question for cleaning Pontoons that have turned bad. It is Mother's Wheel Mist [linked by editor to product info at Amazon] just spray it on wait for action to stop about 5 min and hose off. It will not shine like New but it will look Great.Gary H [last name deleted for privacy by Editor]

A. I found on Bennington's Website they recommend Oxisolv's Aluminum Cleaner to clean the pontoons. Here's the link to Oxisolv's website:
If possible, check the manufacturer's website for your particular boat, they should have similar information on cleaning products for your boat.

Q. We just got a new pontoon and Barkeepers Friend [linked by editor to product info at Amazon] seems to work really well. I hope I am not ruining anything but it keeps the pontoons like new. Takes a bit of scrubbing but I use very mild abrasive sponge works wonders so far and don't scratch.Pat [last name deleted for privacy by Editor]

Q. My 5 year old pontoon, a sylvan, has pits and oxidation to the point of near holing....during the summer here it spends all its time in the water. my question is what to do to halt the action and what can I do to save the existing tubes?Harold L Blanchard

A. Cleaning boats is not that difficult. You just have to find the right cleaners. We manufacture Brite 1 which cleans aluminum. If its not extremely coated with lime deposits and scum, and such especially underneath the boat, then you can use our Beauty Brite, Wizard Product Line. Getting that clean, sparkling look just takes a little maintenance.

Q. I just purchased a 1986 Weeres pontoon boat. It is in good shape for it's age. However, the aluminum pontoons are heavily pitted but they don't leak. I am considering coating the pitted areas with a truck bed liner material. Is this a good approach to prolonging their life or can you suggest something better.
Kindly respond, TimTimothy W Shaw

A. We make what you are looking for. It is called 1 Step Aluminum Cleaner. We sell to all the local boat people here in SC. 1 gallon makes 5 gallons of cleaner you just spray it on and let sit for 5-10 minutes and you wash off with a water hose your pontoon will look brand new. It takes no work at all.Dawn Styles

Good luck, Bill :-)
You've seen seven recommendations on this page, and there is zero chance of any of the vendors publicly saying "Oh, yeah, that's right, I forgot, Brand Z Pontoon Cleaner is actually much better than what we offer" :-)
Just pick one. I'm confident that all are designed for the purpose.

Q. I have a 43 houseboat that has been in the water since Sept 07. Is there a way the pontoons can be reasonably cleaned while in the water? We don't mind making it a elbow grease project, but any tips would be appreciated.Steve Richards

Q. I like to fish at the coast. I have a 24 ft pontoon that is giving me a problem. I am looking for information about an epoxy or metal filler to use on the pontoons. The salt is getting trapped between the carpet and pontoons causing pitting in the aluminum pontoons. Is there an epoxy or metal filler that can be used to seal and coat the bottom of the pontoons to slow this process.Manuel Roberts

Q. I HAVE A SYLVAN PONTOON BOAT THAT I KEEP IN THE WATER ALL YEAR IN HOMOSASSA FL. ONCE EACH YEAR I GET THE PONTOONS POWER WASHED. THE MARINA SAYS ALMOST ALL THE PAINT IS WORN OFF THE PONTOONS AND I SHOULD GET IT RE-PAINTED. IS HAVING IT POWER WASHED EVERY YEAR ENOUGH OR DO I REALLY NEED IT PAINTED?michael murphy

A. As for cleaning your pontoons check with your napa auto parts store they sell a cleaner for your pontoons that is very good; and to coat your pontoons in redding, ca paint mart you can get a coating that is a good price at 167.00 for a five gal can and works good; looks like tar but dries hard and lasts a long time and it is called "cold cat". thanks, scottscott jensen

Q. We have a metal pontoon boat with water stains down the sides from the tarp. We have tried just about everything to try and remove them. It is beige with decals so we have to be careful when we use our power washers on it. Would appreciate any suggestions you might have to remove them without removing the paint.

A. Hi this sounds really strange but I have used cheap toilet bowl cleaner thinned about 1/2 with water use a spray bottle spray the solution on the pontoons and rinse with garden hose do not leave the solution dry on the pontoon with out rinsing off. I only did small section at time before hosing section off.
Hope this helps.

Q. We have a 3-toon pontoon boat and ours was oxidized and stained black where it sat in the water. I took an acid based aluminum cleaner to them and washed that off. It came out clean but white. So I used our buffer and some PPU Metal Polish and it came out very nice. It has a good shine. I am now looking into what to put on them as a protector so they hold their shine longer.Taylor McCabe
