How Much PSI to Pressure Wash a Boat?
The amount of pressure washer PSI (pounds per square inch) needed to clean your boat depends on the type of surface you are cleaning. For example, if you are cleaning a fiberglass boat, you will need a lower psi setting, around 1,500 to 2,000 psi, to avoid damaging the gel coat.
On the other hand, if you are cleaning a metal boat, you can use a higher psi setting, around 3,000 to 4,000 psi, to effectively remove dirt and grime.
Here's a table that lists some common types of boat surfaces and the suitable PSI (pounds per square inch) for cleaning them:
| Boat Surface | PSI |
|---|---|
| Fiberglass | 1,500 – 2,500 |
| Gelcoat | 1,500 – 2,500 |
| Aluminum | 1,000 – 2,000 |
| Steel | 1,000 – 2,000 |
| Wood | 500 – 1,500 |
| Vinyl | 500 – 1,500 |
| Canvas | 500 – 1,500 |
How to Pressure Wash a Trailered Boat
Pressure washing a trailered boat can be a bit more challenging than pressure washing a boat that is in the water. Here are the steps you can follow to pressure wash a trailered boat:
Step 1: Prepare the Boat
Before you start pressure washing, make sure the boat is clean and free of any debris or obstructions. Remove any loose dirt or debris with a soft-bristled brush or a pressure washer with a low psi setting. This will help prevent any dirt or debris from getting stuck in the pressure washer's nozzle or hose.
Step 2: Choose the Right PSI
The next step is to choose the right psi (pounds per square inch) setting for your pressure washer. The psi setting will depend on the type of surface you are cleaning. For a trailered boat, you will typically want to use a lower psi setting, around 1,500 to 2,000 psi, to avoid damaging the gel coat or fiberglass surface.
Step 3: Set Up the Pressure Washer
Once you have chosen the right psi setting, set up the pressure washer by attaching it to a garden hose and making sure all connections are secure. Make sure the pressure washer is set to the appropriate psi setting and that the nozzle is clean and free of any debris.
Step 4: Start Pressure Washing
Begin pressure washing the boat from the top down, using long, even strokes to cover the entire surface. Make sure to keep the nozzle at a consistent distance from the boat's surface and to use a steady, even pressure. Avoid using high-pressure jets of water that can damage the boat's surface.
Step 5: Clean the Hull
Starting at the bow (front) of the boat, use the pressure washer to clean the hull, working your way along the sides and bottom of the boat. Use a gentle, sweeping motion to remove any dirt, grime, or algae from the hull. Avoid using harsh chemicals or abrasive cleaners that can damage the boat's surface. Keep the nozzle 6 to 12 inches from the boat’s surface.
Step 6: Clean the Deck and Cabin
Once you have cleaned the hull, move on to the deck and cabin. Use a soft-bristled brush or a pressure washer with a low psi setting to remove any dirt or debris from the deck and cabin. Be gentle when cleaning the cabin to avoid damaging the windows, doors, or other sensitive areas.
Step 7: Rinse the Boat
After pressure washing, rinse the boat thoroughly with clean water to remove any remaining dirt and soap residue. Make sure to rinse the boat from the top down to avoid streaks or water spots.
Step 8: Dry the Boat
After rinsing the boat, use a clean, dry towel or chamois to dry the boat's surface, paying extra attention to any areas that may have been damaged during the pressure washing process.
Step 9: Inspect and Repair
Inspect the boat for any damage or areas that may have been damaged during the pressure washing process. Check for any scratches, dents, or other damage that may require repair before moving the boat.
Step 10: Maintain the Boat
Maintaining the boat regularly, cleaning the boat thoroughly, and making sure that all connections are secure. Make sure that the boat is secured properly.
How Much Does it Cost to Pressure Wash a Boat?
The cost of pressure washing a boat can vary depending on the size of the boat, the type of surface, and the location where you live. On average, the cost of pressure washing a boat can range from $100 to $300, depending on the complexity of the job and the size of the boat.
