Boat Cleaning


Before launching your new boat for the first time, clean your painted panels with boat soap and warm water using a soft sponge or cloth, and apply a coat of marine grade wax only (without cleaners). This will make it easier to maintain your boat in the future.

Note! It is strongly recommended that after each use, you rinse your boat off with fresh water, and dry with a soft towel or chamois to remove water spots.


To remove water spots and stubborn dirt that has been allowed to dry on the panels, you can try the following items:

  • Boat soap and warm water
  • Denatured alcohol
  • Ace Glass Cleaner
  • Fantastic Heavy Duty Cleaner
  • Armor-All Cleaner

All products listed above are to be applied with a soft cloth and minimum pressure.


It is ok to use marine or automotive waxes that do not have any petroleum distillates or abrasives such as:

  • 3M Marine Paste Wax
  • 3M Liquid Wax
  • LeVernier Custom Polish

Note! Aggressive rubbing in one spot can damage the paint with any cleaning solution. Test cleaners and wax in a small area before using on entire boat.

Do Not Use:

  • Any paint thinner, MEK, Acetone, or any other solvent-based thinners/cleaners
  • Any cleaners or polish with abrasives, such as rubbing compound
  • CLR or Clorox based cleaners

Boat Furniture Cleaning Tips

To keep your boat seats looking their best, clean the vinyl covers using the following cleaning techniques:

For general purpose cleaning, use 303 Products Cleaner & Spot RemoverFantastic (container must state it can be used on vinyl), or mild dish soap (such as Dawn or Ivory) and very warm water. Then, gently scrub with a small soft bristle brush. Rinse soap and cleaning residue off with water and then dry. Purchase our 303 Products Cleaner & Spot Remover.

For dirt build-up, use 303 Products Cleaner & Spot Remover, Let soak for approximately 10 minutes, and then gently scrub with a soft bristle brush.

Use these products to clean your vinyl-covered boat interior:

  • 303 Products Cleaner & Spot Remover
  • Mild dish soaps (such as Dawn or Ivory)
  • Fantastic (container must state it can be used on vinyl)
  • 303 Protectant

Do Not Use These Products to Clean Your Vinyl-Covered Boat Interior

Goo B Gone, Formula 409 (bottle states “Not for use on vinyl”), Murphy’s Oil Soap, Simple Green, DC Plus, ArmorAll, Top Kote Sealant, Son-of-a-Gun, Orange 88 Degreaser, Roll-Off, Bleach/Baking Soda, Turtle Wax/Tar Remover (containers state “Not for use on vinyl”), APCO, Harbor Mate, or other harmful cleaners.

Do not use kerosene, gasoline or acetone, as they will remove the protective marine top coat.

Do not use any silicone or petroleum based products. They will extract the plasticizers in the vinyl, leave it hard and brittle, and eventually cracking may occur.

Do not use a power washer on boat seating upholstery.

Other Marine Vinyl Cleaning Tips: It is a common misconception that household bleach, chlorine based cleaners, and other strong commercial cleaning solutions are good for treating stains on vinyl-covered boat.
