How to Clean a Boat Hull

Lead Image

If you own a boat and you have difficulty maintaining its hull, you should learn the proper way of cleaning it. Even though the boat hull looks smooth and resilient, it is still susceptible to standard damage, including normal wear and tear. Constant contact with water corrodes the material and can cause cracks over time. Over time, these can not only damage the integrity of the boat, but may also cause leaks. Algae can also form on the surface of the hull. In order to keep your boat hull sturdy and attractive, follow these steps for efficient boat hull cleaning.

Materials Neeed

  • Hose or Bucket
  • Fresh water supply
  • Hull cleaning substance
  • Sponge (2)
  • Scuba gear
  • Dinghy
  • Gloves

Step 1 - Wash the Hull

Aim a hose attached to a fresh water supply at the boat hull to strip off clinging salt and algae. If you don’t have a hose, you can use a bucket to throw fresh water at the hull. It is recommended that you wash the hull often with fresh water in order to avoid buildup of foreign material. For more effective cleaning, you can ride a dinghy alongside your boat to get to the lower area of the boat hull.

Step 2 - Use Cleaning Substance

Hull cleaning substances are specially formulated to provide optimum cleaning to boat hulls. Mix a hull cleaning substance with water according to the instructions. You can apply it by using a bucket or sponge. Use gloves to protect your hands from the hull cleaning substance and avoid any allergic reactions.

Step 3 - Apply Sponge to Boat Hull

After dipping the first sponge to the hull cleaning substance, rub it on as much boat hull area possible. Use a large sponge to clean the boat hull more efficiently. If foreign material can’t be removed from the boat hull by your sponge, utilize a more abrasive sponge. Make sure that you don’t scratch the boat hull when using an abrasive sponge.

Step 4 - Wash Again

Once the hull cleaning substance has been applied, it’s time to rinse the boat hull with fresh water. Use a hose or bucket to rinse the boat hull thoroughly. Dip the second sponge with fresh water and scrub off the hull cleaning substance from the boat hull.

Step 5 - Scuba Cleaning

This is an optional step intended for experienced scuba divers only. If you have scuba equipment and proper training, you can clean the underside of the boat hull by yourself. Use an abrasive sponge to scrub away foreign material from the part of the boat hull submerged in water.
