How Does a Boat Cleaner or Boat Soap Help to Protect Your Boat?

Buildup of salt and dirt interferes with a metal’s ability to resist corrosion. Gelcoat and marine vinyl are porous surfaces, meaning they have the ability to absorb water, dirt, and grime from their surroundings. Unprotected vinyl seats are more likely to develop mold and more likely to fade and crack with frequent sun exposure. Lastly, fiberglass that is uncared for will stain and discolor more easily over time, notwithstanding simply degrade through oxidation and literally chalk away.

These are all reasons why cleaning your boat’s many surfaces is the single most important step in protecting them. It’s important to understand that there are different types of cleaning solutions for different parts of your boat. It’s a dangerous belief that household bleaches and cleaners are OK to use on your boat; they might appear to do the trick at first, but in the long run they could end up causing unwanted deterioration.

To make protecting your boat a lot easier, PartsVu has assembled a list of recommended boat cleaner products from leading brands like StarBrite, 303 Products, 3M, Meguiar’s, and more.
