Cleaning Lake Scum Off Your Aluminum Boat: Easy Steps

Keeping your boat clean is essential not only for its appearance but also to protect its value. If your boat has been in the water for a long time, it will likely have a brown scum line around the hull. To prevent permanent staining, it is important to clean your boat regularly and thoroughly. This paragraph will discuss the best ways to clean lake scum off your aluminum boat, ensuring it stays in top condition.

Use a mild detergent and warm water

To clean lake scum off an aluminum boat, a mild detergent with warm water is a safe and effective method. This method is recommended by Alumacraft for their aluminum boats. It is important to avoid abrasive cleansers or solvents that could damage the finish of your boat.

First, ensure you have gathered the necessary materials and tools: freshwater, a mild detergent, warm water, a wet rag, soft cloths, and a hose. You may also want to wear rubber gloves to protect your skin from the detergent.

Begin by rinsing your boat with fresh water, especially if it has been exposed to salt, polluted, or brackish water. This is an important step to remove any loose dirt or debris before applying the detergent.

Next, mix the mild detergent with warm water. The detergent should be diluted according to the instructions on the product label. Dip a soft cloth or sponge into the detergent solution and apply it to the scummy areas of the boat. Work in small sections to ensure thorough coverage. Allow the detergent to sit on the surface for a few minutes to loosen the scum.

Finally, rinse the boat with fresh water again to remove the detergent and loosened scum. Use a hose to ensure all detergent residue is removed. Dry the boat thoroughly before applying any protective coatings or returning it to the water.

For more stubborn scum, you may need to use a soft-bristled brush to gently agitate the scummy areas after applying the detergent. Alternatively, there are specialized aluminum boat cleaners available, such as XPS Aluminum Cleaner or Presta Marine Deck Spray, which can be used according to the manufacturer's instructions.

Avoid abrasive cleansers

When cleaning lake scum off an aluminum boat, it is important to avoid abrasive cleansers or solvents that could damage the finish of your boat. Instead, opt for mild detergents or specialised boat cleaning products.

For example, XPS Aluminum Cleaner is a product formulated to quickly and safely remove waterline scum, algae stains, mould, and oxidation from aluminum boats, leaving a bright, clean finish. It is important to follow the manufacturer's instructions when using this or any other product.

Another option is to use a diluted vinegar solution. This natural cleaner is effective at removing scum and water spots without damaging the boat's finish. Simply mix one part vinegar with three parts water in a spray bottle and apply it to the affected areas.

If you are dealing with tough stains, you can use a product like Starbrite "Instant Hull Cleaner", which is safe for aluminum. Apply it with a sponge, wait a few minutes, and then rinse it off with water. Always wear rubber gloves when handling cleaning products and follow the safety instructions on the label.

Additionally, to prevent lake scum from building up in the first place, it is recommended to rinse your boat with fresh water after each use, especially if it has been exposed to salt, polluted, or brackish water. Regular maintenance and cleaning will help to preserve the appearance and value of your boat.

Rinse with fresh water after each use

Rinsing your boat with fresh water after each use is an important step in maintaining the appearance and value of your boat. Here are some detailed tips and instructions to ensure effective rinsing and protect your aluminum boat from lake scum:

Firstly, it is crucial to rinse your boat with fresh water after each use, especially if it has been exposed to salt, polluted, or brackish water, or if you have travelled over salty roads. This helps prevent the buildup of lake scum and other contaminants. Make sure to pay extra attention to the hull of your boat, as this is the area most susceptible to scum accumulation.

After rinsing, use a wet rag to wipe away any visible scum line around the hull waterline. This is important because dried scum can be challenging to remove and may eventually stain the hull. If the scum has already dried, you may need to use a mild detergent or a specialized cleaner to remove it.

Additionally, consider investing in a good boat wash product or a mild detergent to periodically clean both painted and unpainted hull surfaces. Avoid using abrasive cleansers or solvents, as these can damage the finish of your boat. For a more comprehensive clean, you can also use a soft-bristled brush to gently scrub the hull and remove any stubborn scum or stains.

Finally, always allow your boat to dry thoroughly before covering or storing it. Proper drying helps prevent the formation of mildew and unpleasant odors. Following these instructions consistently will help maintain the appearance and value of your aluminum boat, ensuring it stays in top condition for years to come.

Wipe away scum with a wet rag

To clean lake scum off an aluminum boat, it's important to act fast. Lake scum can cause permanent stains if left for too long. The first step is to rinse your boat with fresh water, especially if it has been exposed to salt, polluted, or brackish water.

Then, immediately wipe away the visible scum line around the hull waterline with a wet rag. This is crucial, as dried scum is harder to remove and can leave stains. Use a soft cloth to wipe away the scum, and be sure to do this as soon as you haul the boat onto its trailer.

If the scum line is particularly stubborn, you can try using a mild detergent or aluminum cleaner. Apply the cleaner with a wet rag or soft cloth, and be sure to rinse the boat thoroughly afterward. With prompt action and the right tools, you can effectively remove lake scum from your aluminum boat and keep it looking its best.

Use a powerful cleaner and degreaser

To clean lake scum off an aluminum boat, you can use a powerful cleaner and degreaser like Presta Marine Deck Spray All-Purpose Cleaner. This product is highly concentrated, non-caustic, and aluminum-safe. It is designed to remove heavy dirt, grease, stains, and streaks from fiberglass, metal, and painted surfaces.

When using this product, follow these steps:

• Spray the Deck Spray onto the boat's hull.
• Let the product dwell for 2-3 minutes. It is important not to let it dry.
• Try wiping the stain with a soft microfiber cloth.
• If the stain persists, use a soft brush to agitate the area and then rinse with clean water.
• For tough stains, you may need to apply a little more elbow grease and repeat the process.

It is recommended to wash your boat regularly with a product like Ultra Concentrated Boat Wash to prevent lake scum buildup. Additionally, you can use a protective coating like Presta Marine Hydroproteck Ceramic Spray Coating to create a hydrophobic barrier that repels water and lake residue, making it easier to keep your boat clean.
