Boat Hull Cleaning & Restoration

Months of exposure to the elements means your boat hull and topside are in need of a good cleaning. While many boat owners have traditionally chosen power washing with water, this is simply not an effective solution.

Grit-O’Cobs corncob media provides the ideal solution for boats with wooden hulls and fiberglass boats, which can be cleaned with one application, without destroying the gel coat.

Other products are harmful, messy, abrasive, expensive and can leave a residue. Grit-O’Cobs is the safe, efficient and eco-friendly answer you need.

Which Grit-O’Cobs Product Should I Use?


We recommend the use of Grit-o’Cobs 2040 for pontoon boat cleaning. While applications may vary, a typical pontoon boat will require 2-3 40 lb bags of product.

Application is as simple as 3 easy steps:

Step 1) Pour Grit-O’Cobs into a clean pressure pot

Step 2) Wear protective eyeglasses

Step 3) Restore your boat to its preseason shine



While we recommend Grit-O’Cobs 2040, there may be additional options for your project. For help, visit our products page or contact our customer service team today!
