Dock rash is a common issue for boat owners, and it can be a frustrating eyesore. It occurs when a boat comes into contact with a dock, causing unsightly marks and scratches on the boat's surface. While it may seem like a daunting task to remove these blemishes, there are several methods that boat owners can employ to restore their vessel's appearance. The chosen method depends on the severity of the rash and whether the boat is painted or not. For instance, using acetone to dissolve the rash is not recommended for painted boats, as it can damage the paint and decals. Instead, a buffer with a very fine polishing compound can be used to polish out the marks, or a rag with some polishing compound can be used for a gentler approach. For more severe cases, a professional mariner recommends stripping the paint around the damage, using an auto body filler to cover it, and then sanding until smooth. Additionally, some owners opt to cover the dock rash with stickers or decals.

What You'll Learn
Sweep your dock regularly
Keeping your dock clean is necessary for it to look its best and to ensure it lasts for years to come. Sweeping your aluminium dock regularly is an easy way to maintain its shine and lustre. Here are some tips for sweeping your dock:
- Use a broom with soft bristles to gently sweep the surface of the dock. Avoid using a broom with stiff or wire bristles, as these can scratch the aluminium.
- Sweep your dock at least once a week, or more frequently if it is in a high-traffic area or if there is visible dirt and debris buildup.
- Pay special attention to the areas where people walk the most, as these areas are more likely to accumulate dirt and debris.
- If you have a large dock, consider using a leaf blower to help you quickly remove loose dirt and debris.
- After sweeping, inspect the dock for any remaining dirt or debris. Use a soft-bristled brush to gently remove any stubborn dirt or debris that the broom may have missed.
- If you notice stains or discolouration on the aluminium, a mild dish soap and water solution can be used to scrub the affected areas. Be sure to use a non-abrasive cloth or towel to avoid scratching the surface.
By following these tips, you can keep your aluminium dock looking clean and shiny, while also preventing the buildup of dirt and debris that can lead to "dock rash".

Wash with a vinegar solution
To remove dock rash from your aluminum boat, you can wash it with a vinegar solution. This is an effective way to remove difficult stains without damaging the metal.
First, create a mixture of equal parts distilled water and white vinegar. Fill a spray bottle with this solution and then spray it onto the affected areas of your boat. Allow the vinegar solution to sit on the aluminum for a full minute so that it can react with the metal. Next, dip a non-abrasive towel or cloth in water and use it to wipe away the solution. It is important to thoroughly remove all traces of vinegar so that it doesn't continue to react with the aluminum.
If you don't have vinegar, you can also use a mixture of baking soda and water in the same way as the vinegar solution. Remember to wipe off the baking soda solution when you're done cleaning.

Use lemon and salt to remove tough stains
Lemon and salt can be used to remove tough stains from aluminum. This method is particularly useful for cleaning aluminum cookware and utensils. Here is a step-by-step guide:
Step 1: Prepare the Lemon and Salt Solution
Cut a lemon in half and dip it in table salt. Ensure that the salt crystals stick to the lemon by gently pressing or stirring the lemon into the salt.
Step 2: Apply the Solution to the Aluminum
Using the salted lemon, gently scrub the stained areas of the aluminum. For larger surfaces, you can cut a lemon slice and rub it over the surface until the stain is removed.
Step 3: Rinse and Dry
Once the stain is removed, rinse the aluminum with water. For tough stains, you may need to repeat the process. Finally, dry the aluminum thoroughly with a clean, dry cloth.
Additional Tips:
- For burnt-on food in aluminum cookware, cover the bottom of the pan with water, add a few tablespoons of vinegar, and boil for about 10 minutes. Let the water cool down, then pour it out and scrub gently with a sponge.
- Lemon juice can be substituted with other fruit acids such as apple or rhubarb stalks.
- For smaller aluminum utensils, you can boil them in a pot of water with lemon juice, apple peel, or rhubarb stalks for about 10 minutes.
- Always wear gloves when cleaning with an acidic solution to protect your hands.
- Avoid using metal sponges or scrubbers as they can scratch the aluminum.
- Regular cleaning will help prevent the buildup of tarnish and make it easier to remove light stains.

Pressure wash your boat dock
Pressure washing your boat dock is a great way to keep it clean and well-maintained. Here are some detailed instructions to help you get the job done effectively and safely:
Conduct a Pre-Inspection
Before you start pressure washing, it's important to inspect the dock thoroughly. Look for any loose, splintered, or rotting boards, as well as rusted or corroded nails and screws. Address these issues first to prevent further damage from the high-pressure water. A pre-inspection will also help you determine the appropriate pressure washing techniques and attachments to use. For docks made of softwoods or hardwoods, a gentler approach like soft washing is recommended. For more durable materials such as pressure-treated wood, composite, or concrete, higher water pressure can be used.
Prepare the Area
Remove any detachable objects from the dock, such as grills, bars, cushions, canopies, and electrical equipment. These items can be damaged by water pressure or break away if mounted on the dock. It is also important to close all windows, portholes, and hatches to avoid getting the interior of the boat wet. Additionally, make sure to wear proper protective gear, including eye protection and clothing that covers your skin, to prevent injuries from water pressure or flying debris.
Choose the Right Equipment and Settings
For pressure washing your boat dock, it is recommended to use a pressure washer with adjustable settings. Start with a lower water pressure and gradually increase it as needed. For delicate woods or materials, set the pressure washer to about 1,200 to 1,500 PSI and use a wider 45-degree or 65-degree nozzle to prevent damage. For more durable surfaces like composite and concrete, you can use higher pressure settings of 2,000 to 3,000 PSI with a 15-degree or 25-degree nozzle. Always follow the manufacturer's instructions and recommendations for your specific pressure washer model.
Apply an Eco-Friendly Cleaning Solution (Optional)
Before pressure washing, you may want to apply an eco-friendly cleaning solution to the dock surface. This will help loosen up dirt, dust, and debris. Look for a gentle, environmentally safe soap that won't harm marine life or plants. Follow the manufacturer's instructions for mixing and applying the solution. Allow it to sit for a few minutes before rinsing.
Scrub the Surface (Optional)
Depending on the condition of your boat dock, you can use a manual brush or a scrub attachment to clean the surface. This step is especially useful if you are using the soft washing technique with low-pressure water. Be gentle when scrubbing to avoid damaging the wood or other materials. Always read and follow the instructions on the cleaning solution container regarding scrubbing requirements.
Pressure Wash Your Boat Dock
Now it's time to start pressure washing! Hold the pressure gun a few inches away from the surface and start with low water pressure to test the surface. Gradually increase the pressure as needed, being careful not to damage the dock. Work systematically across the dock, maintaining a consistent distance and speed to ensure even cleaning. Pay extra attention to areas with stubborn dirt, algae, or mildew. Remember to proceed with caution and follow all safety guidelines to avoid injury or damage.
Apply a Wood Stain or Weatherproofing Sealant (Optional)
After pressure washing, you may want to consider applying a wood stain or weatherproofing sealant to your boat dock. Since the surface is now clean, the stain or sealant will adhere better and provide enhanced protection and a fresh appearance. Choose a stain or sealant that is specifically designed for boat docks and follow the manufacturer's instructions for application.
By following these steps, you can effectively pressure wash your boat dock, making it look clean and well-maintained while also protecting it from dirt, damage, and the elements. Remember to always put safety first and choose the right equipment and settings for your specific dock material.
