How To Get Black Stains Out Of Pontoon Carpet

How to get black stains out of pontoon carpet – There’s nothing worse than black stains is there? Well perhaps there is, and that would be if pests and mice have got into the boat during the winter. Your boat carpet sees a lot of traffic. Whether it’s human feet or pet feet, that dirt can add up. Soil and stains can do a number on your carpet. Not only can they make it look bad (or even gross) but they can harbor bacteria and mold that make onboard guests sick and eat away at the carpet and deck. Yuck.

Your pontoon carpet is exposed to rain and sun on a regular basis, and if you don’t store it properly in the winter, snow and ice can cause problems too. And I mean cringe-worthy problems like mold, mildew, moss and fading. Learning how to get black stains out of pontoon carpet is the first step towards your pontoon boat maintenance.

Pontoon boats are often left outside in the rain and humidity, thus increasing the chance of moss growth on the synthetic carpeting. Most commercial moss killers are actually toxic to marine life and plants, so you cannot spray them or wash them off while the boat is near any type of water way. Attempt the least toxic moss removal method first, although it is always a good idea to clean your pontoon carpeting on dry land to avoid contaminating the water.

The most important things first.  Before cleaning with anything, even with water, you need to check your carpet material.  What is it made of?  Some of the most common materials are polyester fibers and artificial grass, which should be quite good for washing with water and a carpet cleaner.  It all depends on what is the carpet made of.  Most pontoon boat rugs are made from synthetic fabrics such as polypropylene or acrylic and can withstand the most aggressive cleaning. . If you’re not sure, you should do tests in a small inconspicuous spot first before tackling the entire carpet.

Then, there are other considerations. Does your carpet have marine-grade backing, long-term UV protectant or mold/mildew sealer or protectant? If it does have long-term treatment with these things, then you’re all set to wash—you’ll just want to check out the sealers and protectants and make sure you don’t end up using any chemicals that negate their effects or reduce their potency. If it doesn’t have any treatment, you may want to look into applying such treatments after cleaning.

How to get black stains out of pontoon carpet – Boat carpet is usually treated to prevent the formation of mold. Over time this treatment can wear off, exposing the boat carpet to the moist air.

Once boat carpet gets infested with mildew it is only a matter of time before that turns into mold. When this happens the entire boat can become infected with spores, which will be very bad for your floating investment.
