Sparkle and Shine: The Best Boat Cleaners for a Ship-Shape Vessel
From bow to stern and starboard to port, boats of any size have a boatload of surfaces to clean, preserve and protect.
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 makes the job so much easier (meaning you can use the boat for what it was intended for ... 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 that the 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).

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 cars, so you want to make sure you're using products specifically for boats and marine items, as vehicle cleaning products cannot 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
As mentioned above, some products are conveniently made for all-over use on glass, vinyl, metal, etc., while others are made specifically for wood or metal. Specialized boat cleaners are usually stronger than multi-use products.

Type and How it's Used
- 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, they're where we spend our free time. You'll want to choose boat cleaning products that are non-toxic and don't harm the waterways or the creatures that live in them.
