Why Should You Buy the Best Pressure Washer for Boats?

Before delving into our guide to the best pressure washer for boats, let’s first discuss the reasons for buying such a machine.

For freshwater boats, you will deal with grime, algae and dirt. Cleaning the boat by hand is a tedious ordeal, much like washing a car.

Pressure cleaning is the most efficient and effective way to wash boats. With the best pressure washer for boats, you can choose from several nozzles and use the right one for rinsing and soaping.

How to Choose the Best Pressure Washer for Boats

best boat pressure washer

Now that you have seen our best picks regarding the best pressure washer for boats, how should you choose? Below are some tips that will help you make a decision.

  • Price – choose one that is friendly to your pocket; there are many pressure washers out there, but there is really no need to spend so much money for boat washing. Expensive pressure washers are for professional use.
  • Power Balance – pick one that is above the 1,000 PSI range. If the PSI is too low, it would feel like you are using a garden hose and you do not want that. On the other hand, you do not want too much pressure, as it can damage the paint.
  • Accessories – pick the product that offers the most accessories, especially those that have a detergent tank or a soap nozzle. These features come in handy so you do not have to buy them separately.
  • Choose Electric – gas-powered washers are excellent if you will use them in a place without access to power. However, electric washers are the way to go if your boat is in your garage. Electric pressure washers are great for continuous use, and they are more silent than gas-powered ones.

When selecting the best pressure washer for boats, pick a pressure washer that is Medium Duty. Heavy-duty washers are for professionals, but light-duty ones may not be able to do the job. Medium duty washers are those that are in the 1,800 PSI to 3,000 PSI range.  

Lastly, it is up to you to choose cold water or hot water pressure washers. Hot washers clean better, but they are much more difficult to operate.
