How to Clean a Pontoon

The pontoons on your boat are going to acquire algae and scale build-up over time, particularly if your pontoon is left in the water for long periods of time. Having your pontoons look as good as new is nice for cosmetic reasons. But maintaining clean pontoons will also benefit you by cutting down on water resistance, and thus fuel costs, as well as prolonging the life of your pontoon. You don't have to take your pontoon to a professional cleaner to get professional-looking results.

Things You'll Need

Plastic knife
Cleaning brush
Spray bottle
Hot water
Pressure washer

Instructions

- 1
  Remove any obvious build-up before using cleaning chemicals. Scrape or knock off mussels, barnacles and any other debris that you can. It will be easiest to do this as soon as you remove your boat from the water. Doing this every time you pull your boat from the water will make it easier to maintain long term. You can scrape off stubborn algae with a plastic knife if necessary.
- 2
  Purchase a cleaner that is designed for the hull of boats. Spray this directly onto the pontoons and let it stand for a few minutes. Use a cleaning brush to help loosen debris if necessary. Using hot water, spray off the residue. A second application may be necessary.
- 3
  Deoxidize your pontoon after you have removed as much build-up as possible. Starting at the bottom, spray an aluminum cleaner onto the pontoon. Leave it on for one to five minutes, and then wipe it off with a clean, non-abrasive cloth. Repeat if necessary.
- 4
  Use a pressure washer on your pontoons, and follow with a waxing and buffing to help them stay clean for longer and to reduce drag, which can save you money on fuel. Although some professionals use an acid solution to clean pontoons, it shouldn't be attempted at home as it can pit the pontoons and remove the factory coating that helps prevent oxidation.
