Pre-inspection: Check for loose boards, rusted nails/screws, softwood/hardwood

Before pressure washing your boat dock, it's important to conduct a thorough pre-inspection. This includes checking for any loose boards, rusted nails or screws, and determining whether you're working with softwood or hardwood.

Start by carefully walking the length of your dock, applying pressure with your foot to check for any loose or rotting boards. Pay close attention to areas that are frequently exposed to moisture, as these are more prone to rotting. If you find any loose boards, secure them properly before proceeding with pressure washing.

Next, inspect all the nails and screws that are visible. Look for any signs of rust or corrosion, as these could indicate weakness in the structure. Replace any rusted fasteners to ensure the stability of the dock during the pressure washing process.

Additionally, identifying the type of wood used in your boat dock is crucial in determining the appropriate pressure washing technique. Softwoods require a gentler approach, such as soft washing, to avoid damage. Hardwoods can withstand higher water pressure and may benefit from power washing to effectively remove mould and mildew.

By taking the time to conduct a pre-inspection, you can ensure that your boat dock is in good condition and ready for pressure washing. This crucial step will help prevent further damage and allow you to select the most suitable washing technique for your dock's specific needs.

Eco-friendly cleaning solution: Use a gentle, eco-friendly soap

When it comes to cleaning your boat dock, it's important to choose an eco-friendly cleaning solution to protect the surrounding marine life and environment. The good news is that a gentle, eco-friendly soap can effectively loosen and remove accumulated dirt, dust, and debris from your boat dock. Here are some detailed instructions and tips for using an eco-friendly cleaning solution:

Choosing an Eco-Friendly Soap

Select a gentle, eco-friendly soap that is safe for the environment and will not cause water pollution. Look for products that are marine life-friendly and plant-safe. There are manufacturers that produce such solutions, like Defy Marine Seal Wood Dock Cleaner, which effectively removes dirt, grime, mildew, and graying from wood. Alternatively, you can opt for natural products like baking soda, known for its stain-removing properties, or white vinegar, which is powerful, biodegradable, and affordable.

Preparing the Eco-Friendly Solution

If you're using a commercial eco-friendly cleaner, follow the manufacturer's instructions for preparing the solution. Typically, you'll need to pour the specified amount into a pump sprayer, depending on the surface area you need to cover. For natural products, you can mix them with water in a spray bottle. For example, you can use full-strength white vinegar or a solution of vinegar, ammonia, baking soda, and water to tackle mildew.

Applying the Eco-Friendly Solution

Using the pump sprayer or spray bottle, evenly apply the eco-friendly solution to the boat dock surfaces. Allow the solution to sit for a few minutes, following the manufacturer's instructions. This will give the soap time to work on breaking down the dirt and grime. Remember to wear protective gear during this process.

Scrubbing (If Necessary)

In some cases, you may need to use a brush or scrubber to gently clean the surface. However, always refer to the instructions on the container, as some eco-friendly solutions do not require scrubbing. If scrubbing is required, be gentle, especially if you're working with delicate wood or materials.

Rinsing with a Pressure Washer

After allowing the solution to work its magic, it's time to rinse the boat dock with a pressure washer. For softwoods, use a pressure setting of about 1,200 to 1,500 PSI, and for more durable surfaces like composite and concrete, you can increase the pressure to 2,000 to 3,000 PSI. Always proceed with caution and start with low pressure to avoid any potential damage. Keep the pressure gun a few inches away from the surface, and wear proper protective gear.

By following these steps and choosing an eco-friendly cleaning solution, you can effectively clean your boat dock while being mindful of the environment and marine life.

Brush/scrubber: Clean the surface with a manual brush or scrub attachment

To clean your boat dock effectively, you can use a manual brush or a scrub attachment. This is a perfect complement to the soft-washing technique, as you will be using low-pressure water.

Before you begin scrubbing, make sure to clear the area of any dirt, dust, or debris. You can use a broom, brush, or even a leaf blower to do this. If you opt for a leaf blower, be sure to choose one that matches your needs.

Once the area is clear, you can start scrubbing. Depending on the condition of your boat dock, you may need to apply more or less pressure. If the dock has a lot of built-up dirt, mildew, or algae, you may need to scrub harder. On the other hand, if the dock is only slightly dirty, a gentle scrub will suffice.

It's important to be cautious when scrubbing, especially if you're using a manual brush. You don't want to damage the surface of the dock, so avoid using too much force. If the dock is made of wood, be especially gentle, as wood can be more delicate.

If you're using a scrub attachment, make sure it is compatible with your pressure washer. The pressure of the water should be enough to spin the brush, so there's no need to apply extra force.

In terms of cleaning solutions, it's best to opt for an eco-friendly, biodegradable option. These types of solutions are safe for both marine life and plants and can effectively remove dirt, grime, mildew, and more. Follow the manufacturer's instructions for application, and be sure to wear protective gear during this process.

Scrubbing your boat dock is an important step in maintaining its appearance and safety. By taking the time to scrub the surface thoroughly, you can ensure that your dock is clean, safe, and ready for many more adventures on the water.
