Using Your Pressure Washer to Clean at the Lake: Keep Boats and Docks Clean

Concerned about the green slime that’s taking over your boat or pier? It’s no secret maintaining a boat takes a good deal of time and energy, but cleaning with a pressure washer will keep your boat and pier looking their best.

Boats and piers are continually exposed to humidity and water, which means they often accumulate algae, mold and mildew. With the help of environmentally safe boat or vehicle detergent, pressure washing your boat and trailer removes built up algae, dirt from the road and invasive species.

Here’s how to do it:

  • Simply scrub the detergent onto the surface. (Make sure you are using detergent that is safe for waterways)
  • Allow the detergent to soak for about 3 minutes
  • Rinse with your pressure washer using a delicate spray pattern.

Side note: this is also a great cleaning method for when you put your boat away at the end of the season.

Alternatively, a quick rinse with your pressure washer on the inside of your boat effortlessly removes sticky drink spills, pesky crumbs and the leftovers from your fishing trip. To avoid damaging your boat or trailer, be extra careful around decals and graphics and don’t get too close while pressure washing. Check out our video for more tips for washing a boat.

Great for piers, too
For weathered piers there’s no substitute for pressure washing and scrubbing with dock detergent—again, use an environmentally safe brand so runoff won’t affect the water quality. Over time, piers become slippery with slimy build-up, but a detergent will quickly remove mold, mildew, dirt, and bird droppings. A clean pier lasts longer and is safer for friends, family and pets.

Approach your pier the same way you pressure wash your deck.

At the beginning or end of the season, apply dock detergent through your pressure washer’s detergent injection system – or by hand if you don’t have this feature. Then scrub with a brush and rinse. Avoid damaging a wood pier by spraying at a 40-60 degree angle and maintaining an 8-12 inch distance from the planks. To make the job a little more efficient, a surface cleaner attachment can speed up the process.

After the planks dry is the perfect time to re-stain and return them to their original state.

So, whether it’s cleaning your boat, trailer, or pier, you’re guaranteed to spend less time working – and more time relaxing – this summer if you work a pressure washer into your cleaning routine.
