Boat Decks And Dish Soap: A Good Cleaning Combination?

Dish soap is a powerful cleaner that can be used to wash boat decks. However, it is essential to note that dish soap can strip wax from boat surfaces, leaving them vulnerable to dirt and grime. While some boat owners use dish soap to remove built-up dirt and grime before waxing, others opt for boat-specific soaps and deck cleaners to maintain their vessel's wax coating.

Pros and cons of using dish soap on boat decks

Using dish soap on boat decks has been a topic of debate among boat owners. While some people advocate for its effectiveness in removing tough grime and stains, others caution against its potential negative effects. Here is a detailed look at the pros and cons of using dish soap on boat decks:

Pros of using dish soap on boat decks:

• Effective cleaning: Dish soap is known for its powerful grease-cutting abilities, making it ideal for removing stubborn grime, fish slime, and stains from boat decks.
• Biodegradability: Some boat owners prefer dish soap because it is biodegradable and environmentally friendly, which is essential for marine environments.
• Accessibility and affordability: Dish soap is readily available in most households and is relatively inexpensive compared to specialised boat soaps.

Cons of using dish soap on boat decks:

• Wax stripping: One of the significant drawbacks of using dish soap on boat decks is its tendency to strip wax. While this can be advantageous when preparing a surface for a new coat of wax, it can also remove the desired wax layer prematurely, leaving the deck vulnerable to the elements.
• Residue attraction: Dish soap can leave behind a residue that attracts dirt, causing the boat to get dirty faster and requiring more frequent cleaning.
• Potential damage to clear coat: Some boat owners have expressed concerns that using "normal" soap, including dish soap, can ruin the clear coat of their boats.
• Environmental concerns: While biodegradable dish soaps are available, some varieties contain phosphates, which are not environmentally friendly and can be harmful to marine life.
• Deterioration of certain finishes: In addition to wax, dish soap may also deteriorate specific boat finishes, such as Sure Step, a commonly used polish.
• Discolouration: There are concerns that using dish soap on boats may lead to discolouration of certain surfaces or components.
• Alternative options: Specialised boat soaps and deck cleaners are designed specifically for cleaning boats and may be gentler on certain finishes while still effectively removing dirt and grime.

In conclusion, while dish soap can be effective for cleaning boat decks, it is essential to consider the potential drawbacks. Specialised boat soaps and deck cleaners may be preferable to maintain the boat's finish and protect the environment. Additionally, it is crucial to follow the manufacturer's instructions and recommendations for the specific boat model and finish.

Best alternatives to dish soap for boat decks

Boat owners should avoid using dish soap to clean their decks. It is extremely caustic and will quickly strip the wax from your boat. Without wax, your boat will oxidize from the sun's UV rays and the dish soap will begin eating into the gelcoat.

Boat Soap

Dedicated boat soaps are formulated to clean your boat without stripping the wax. They are also usually biodegradable. Examples include StarBrite Boat Soap and Shurhold's Brite Wash.

Car Wash Soap

Any vehicle soap or car wash soap will be fine for cleaning your boat deck. Meguiar's regular Carwash soap is a popular choice.

Hull Cleaner

For tougher stains from algae, weeds, or lake scum, you will need something stronger like a hull cleaner. Starbrite Hull Cleaner is a popular choice and can be found at Wal-Mart.

Bleach

Bleach is a powerful cleaning agent that can be used to remove tough stains, but it is extremely harsh and will dull your gelcoat, cause paint to fade, change the color of your vinyl, and corrode your fittings. If you do use bleach, make sure to follow up with a good wax.

Soft Scrub

Soft Scrub is a harsh chemical that will remove stains but will also dull the finish of shiny gel coats and paint. If you use Soft Scrub, be sure to wax afterward.

Water

A simple rinse with clean water can be effective, especially if you regularly maintain your boat. Some boat owners also recommend using a squeegee and a microfiber towel to remove water and any remaining dirt or salt residue.

How to remove wax from boat decks

To remove wax from boat decks, you can use dish soap, but be aware that it will strip the wax from your boat and may cause minor scratches. If you want to use dish soap, Ivory and Dawn are two recommended brands. However, it is recommended to use a boat or vehicle soap, such as Meguiar's regular car wash soap, or Starbrite Boat Soap, as these are formulated for cleaning boat surfaces and will be gentler on your boat's finish.

If you are looking to remove wax as part of your regular boat maintenance, a good option is to use a deck cleaner. Starbrite Deck Cleaner with PTEF is highly recommended by boat owners for its effectiveness in cleaning boat decks. For tough grime, Starbrite Heavy Duty Non-Skid Deck Cleaner is a good option. Softscrub with bleach is another suggested product for cleaning boat decks, although it is unclear what effect it has on wax.

If you are looking for a natural alternative, white vinegar is a good option. It is recommended to use a 1:1 ratio of vinegar to water and to use a soft brush to remove water spots and minerals.

Finally, if you are looking for a quick wash that will not strip your wax, a solution of water and Boat Clean Plus is recommended. This solution will not strip your wax and is environmentally friendly.

How to clean a boat deck

Using Dish Soap

• Dish soap is an effective cleaner for boat decks, especially for removing tough grime, grease, and fish slime.
• However, it is important to note that dish soap can also strip away wax and leave a residue that attracts dirt. Therefore, it should only be used occasionally when you intend to strip the old wax off and start fresh.
• Some people recommend using Ivory DW soap as it is less harsh and effective at removing grease and fish slime.

Alternative Options

• For regular cleaning, it is recommended to use boat or vehicle soap, such as Meguiar's regular car wash soap or Starbrite Boat soap. These are milder and specifically designed for cleaning boat surfaces without damaging the wax or clear coat.
• For tough stains from algae, weeds, or lake scum, you can use a stronger product like Starbrite Hull Cleaner or similar.
• For non-skid decks, a product like Starbrite Non-Skid Deck Cleaner is recommended. It effectively cleans the deck without making it slippery.
• Some people also recommend using a diluted mixture of vinegar and water with a soft brush to remove water spots and minerals.
• For a quick rinse after saltwater use, some boaters use a multi-use shower filled with warm water to rinse off the trailer and boat, diluting the salt and preventing buildup.

How to protect a boat deck

Boat decks require regular cleaning and maintenance to keep them in good condition. Here are some detailed instructions on how to protect your boat deck:

Choose the Right Cleaner

Avoid using dish soap or detergents on your boat deck. While they may seem like a convenient option, they can leave behind a residue that attracts dirt and holds it to the surface. Instead, opt for a cleaner specifically designed for boat decks, such as Boat Clean Plus, Starbrite Deck Cleaner, or Roll Off. These products are effective at removing dirt, grime, and stains without damaging the surface.

Regular Cleaning

Depending on the amount of use your boat gets, aim to clean the deck regularly. For a quick clean, a simple solution of clean water and a mop can work wonders. For more thorough cleaning, use a stiff brush or a soft cloth along with your chosen boat deck cleaner. Pay special attention to areas with stubborn stains, and don't be afraid to put in some elbow grease! Remember always to rinse the deck with clean water after cleaning to remove any remaining residue.

Protect the Surface

After cleaning, it's important to protect the deck surface. Applying a good-quality wax is an excellent way to do this. Waxing your deck will help repel water, prevent stains, and protect against UV damage. Look for a wax specifically designed for boat decks, such as Collinite wax or Woody Wax. Be sure to follow the instructions on the product and reapply as needed.

Additional Tips:

• For a deep clean or to remove tough stains, consider using a small amount of bleach mixed with your boat soap or deck cleaner. Test on a small area first to ensure it doesn't discolour the surface.
• If you're using a pressure washer, be cautious of the pressure and nozzle you use. High-pressure water streams can damage the gel coat and cause leaks.
• Avoid using scrub pads or abrasive tools that can scratch the surface. Opt for soft brushes or cloths instead.
• Keep your boat deck covered when not in use to protect it from the elements.
• Regular maintenance and cleaning will help extend the life of your boat deck and keep it looking its best.

By following these instructions and using the right products, you can effectively protect your boat deck and ensure it remains in good condition for years to come.
