Sparkle and Shine: The Best Boat Cleaners for a Ship-Shape Vessel

From bow to stern and starboard to port, there’s a boatload of surfaces to clean, preserve and protect on boats of any size. Whether it’s a fiberglass hull, canvas sails, Isinglass enclosures or metal cleats (not to mention caring for teak decks and the never-ending story of waxing), a little elbow grease combined with just the right tools and products make the job so much easier (meaning you can use the boat for what it was intended … getting out on the water!).

You can do it yourself or enlist the assistance of offspring, fishing buddies or some random kid in the neighborhood (preferably one who can wriggle his way into the bilge to clean that out). If you can’t find any volunteers, bribery is a good option. We find a promise of fishing and a day on the water usually does the trick (along with a case of beer for the over-21 fishing buddies).  

Let’s get started on the best boat cleaners to keep your boat in ship-shape shape (pun intended).

Elements that can Cause Damage to Boats

First off, what exactly causes damage and dirtiness to a boat? After all, the boat does spend most of its time in water.

  • Algae, barnacles and other marine elements
  • Saltwater
  • Stains, rust streaks and oxidation
  • Bird droppings
  • Mud
  • Oil and gas
  • Dirt, dust and rock chips if trailered or kept on land

Parts of a Boat that Need to be Cleaned and Maintained

While certainly not all-inclusive (there’s always something to forget when it comes to a boat), here’s a look at some of the surfaces you’ll need to clean and protect on a boat.

  • Teak decks and railings
  • Metal fixtures, cleats and other hardware
  • Fiberglass and wood hulls
  • Gelcoat
  • Canvas sails and curtains
  • Isinglass (Note: Don’t use Windex on Isinglass; use something made for clear vinyl or plastic.)
  • Marine vinyl such as seats, cushions and Bimini tops

Benefits of Using the Best Boat Cleaners

Along with the obvious aspect of appearance (Who doesn’t want a good looking boat?), there are some very good reasons for keeping your boat well-maintained and looking snazzy.

Prolongs Life of the Boat

A properly maintained, cleaned and waxed boat will last a lot longer. Barnacles can destroy the paint and gelcoat. Water and marine animals and elements are the perfect environment for rust, corrosion and oxidation. Regular inspections and cleaning of engines, bilges and props keep your boat afloat.

Removes Stains

Remember those marine animals mentioned above? Well, birds, otters and fish can provide plenty of stains, streaks and other unmentionable detritus.  

What to Look for in the Best Boat Cleaners

There are several factors to consider when choosing the best boat cleaners for your boat’s hull, deck, railings and more.

Type of Surface

Boats have gelcoat rather than clear coat like a car, so you want to make sure you’re using products specifically for boats and marine items as vehicle cleaning products can’t be used.

Fiberglass hulls need a different type of cleaner than wood and aluminum hulls. There are products deemed “multi-use,” so be aware before using a new boat cleaner.

Specialized or Multi-Use Cleaner

Mentioned above, some products are conveniently made for all-over use on glass, vinyl, metal, etc. … Others are made specifically for wood or metal. Specialized boat cleaners are usually stronger than a multi-use product.

Type and how it’s Used

From gels, liquids and sprays to brushes and sponges, the best boat cleaners come in a wide array of types and application methods.

  • Gels and Liquids
  • Brush-On
  • Sponge-On
  • Spray-On
  • Wax-On / Wax-Off

Provides Additional Protection

Along with cleaning, the best boat cleaners offer protection from rain, wind and sun damage. They also make future clean-ups quicker and easier as long as you’re diligent with your maintenance and cleaning routines.

Environmentally Conscious

Boaters are known for being considerate and respectful of the oceans and waterways. After all, it’s the place where we spend our free time. You’ll want to choose boat cleaning products that are non-toxic and don’t harm the waterways and creatures that live in those waterways.

It helps to remove light oxidation, dullness and fine scratches while protecting the surface from further damage such as UV damage and normal wear and tear that goes along with the boating life. It really enhances color and shine while bringing out the full richness of the surface color. Use by hand or with a polisher.

Plastic surfaces can get dull and splotchy on boats, especially around saltwater. Plexus Plastic Cleaner, Protectant and Polish keeps new plastics looking new longer while enhancing and protecting the looks and life of used items. Colorful plastics become more vibrant and clear plastics retain that transparent look.

Plexus was originally developed for the aviation industry for use on windshields, so you can count on its heavy-duty capabilities. Use it on vinyl windows, laminated surfaces, mirrors and hatch covers. It works by sealing the plastic pores with a micro-thin layer of wax to protect surfaces and make them scratch and damage-resistant as well as protect against yellowing and debris damage. The aerosol applicator prevents dripping and leaking.
