Hull Cleaning and Waterline Stain Removal

Lake water leaves its mark. A brown or yellow line forms along the waterline from tannins and minerals in the water, scum and algae build up below it, and boats left in the water all season can come out with a film and scale over the bottom of the hull. Scrubbing harder does not help much and scratches the gelcoat.

We use marine hull cleaners made for gelcoat, which dissolve stains and scale rather than grinding them off. They are applied, allowed to work and thoroughly rinsed, and the area around the boat is protected. After cleaning, the hull is washed and can be polished or sealed so stains have less to cling to next season.

Hull cleaning is done with the boat out of the water. On boats with antifouling bottom paint, we clean the topsides and boot stripe and leave the bottom paint alone.

We provide mobile hull cleaning and stain removal across Toronto & the GTA, Halton, Hamilton & Niagara, Lake Simcoe, Georgian Bay, Muskoka, Kawarthas & Haliburton, North Bay & Sudbury, including Oakville, Toronto, Barrie, Collingwood, Gravenhurst and Peterborough.

Boat Hull Cleaning & Stain Removal questions

Boat Hull Cleaning & Stain Removal FAQs

Common questions about boat hull cleaning & stain removal.

What causes the yellow-brown stain on my hull?+
Tannins and minerals in lake and river water, plus algae, stain the gelcoat along the waterline and on the bow. It is very common on boats used on Ontario lakes, especially in cottage country.
Will hull cleaning remove scratches or fading?+
No. Cleaning removes stains and buildup. Scratches, swirl marks and chalky oxidation are fixed by polishing, which can be added to the same visit.
Can you clean a hull with bottom paint?+
We clean the topsides, the boot stripe and the transom. Antifouling bottom paint is a separate system and is not something we strip or repaint.
When is the best time for hull cleaning?+
Right after haul-out, before the stains set over winter, or in spring before launch. Stains are easier to remove when they are fresh.
