Pontoon cleaner

[catalina1]

I have a pontoon mooring . There is no electric.
Its covered with slippery algae and mildew.
What chemical might be suitable for cleaning ?
Patio magic?

Patio Magic will be fine for getting rid of the algae, but it does have a warning on its MSDS.

Here's the warning

If you want to go green, then some plain builders sand and a stiff brush will remove the plant and animal life, and provide a grippy surface.

I've just discovered oxalic acid powder (cheap as chips on ebay) Mix with hot water as per instructions on bottle; fast and effective.

Keep away from plated metal. Will 'grey' A2 stainless. Does not touch A4 and removes verdigris & patina from bronze. Excellent for rust stains and slime.


Basically strong 'patio magic'

P.S. dangerous when released into the environment, so undoubtedly effective...

Why is it dangerous when released into the environment? It is a natural constituent of (for example) rhubarb leaves, which happily rot down into the soil if used as green mulch. Rhubarb leaves contain enough to be poisonous, so it isn't trace amounts we're talking about. And I've washed it off onto my lawn several times without any effect at all.

Yes, Oxalic acid is poisonous and dangerous to people, but as far as I know it it does no harm to the environment.

They used to use Lime on the wooden slip at a YC I once used.

Try dishwasher powder. Seems to work well.
