I need help on how to remove horrible black mould spots from the non skid texture in the gel coat on the front deck.

It's only in the last 6 to 9 months this has occurred so any advice would be appreciated.

I have tried deck clean products and exit mould with little difference.

scrub off with hard nylon brush , i have used sugar soap in fresh water for inside boat . works a treat .

outside boat .. scrub off with hard nylon brush and salt water . no problem .


you will maybe get a hundred different options here .


i bet they all have one common theme ........ elbow grease ,..... scrubbing!!!!!...... mechanical removal of crap, the best way .

Oxalic acid or "Metal Gleam", local product containing various acids used in the fishing industry. Bunnings for a deck cleaner [house deck kind]. Oxalic acid is generally the way to go. Use it on the whole boat when you slip. In this case scrub with a nylon brush, rise off.

Hi...
Me too had cleaned mold using brush and finds it successful. But after some month again it appears and I realized that my effort was total waste. I approached a home improvement agency as my brother told. They done some mold inspection http://www.healthyenvironmental.ca/services/mould-inspection/ , proper removal and remedial steps were taken. Now I am glad to see my mold free home...even after a year.
Hope these will make you think....

I once had mould on a soft pink hairy deck so I used our new gum tease 2000. Gets your mouth washed out in half the time. You just grab it n push it into your mouth. Get it right down to tickle your tonsils like every girl should on hubbys birthday.
