I've used "Lock Keepers Secret" in the past.

Expensive but reasonably effective.

You could try some patio cleaner, which should be cheaper and possibly more effective.

You'd need to check to make sure that the brand you use is safe for the waterways...

I use any "boat wash" in water and elbow grease. You may need a scrubbing brush on non-slip surfaces. "boat wash" because it should not harm the environment despite the International version saying it should not go into water courses. I have also used sugar soap to good effect but am not sure what it does to the paint finish.

Yes. It is well regarded in caravanning circles.

 

Do you mind keeping it to yourself though its often hard enough to get hold of as it is....

Does anyone know of an effective solution to removing green mould from the topside of a boat?

 

Power washer?

 

Hi,

 

A power washer is tempting, but use with care or if you have any microscopic blistering on your paint you will find the top paint surface is blown off and numerous white dots appear, preparation and over-painting is then needed. this is particularly prevalent on on flat surfaces finished with 'Raddle Red'.

I'm not sure if we really want patio cleaner and some of these other solutions in our waterways?

 

Often a boat will get green algae on its shady side if it's moored for long periods with no direct sunlight on that side. Turning the boat around occasionally can help to prevent it.

Jays fluid is good at killing the alge, just brush it on leave over night and wash off.

Water! Wait until a damp foggy day and the stuff goes soft enough that it will come off with a mop, elbow grease and plenty of water, whereas in hot dry weather it goes rock hard.

I'm not sure if the use of elbow grease is environmentally friendly, i.e. compatible with the environment of the canals and rivers.

I see many algae and vegetation-covered boats lying in (otherwise) idyllic rural locations that have clearly not had any elbow grease expended on them in years.

Clearly the environment in the area has not been degraded apart from the domestic junk that accumulates on the immediately adjacent river/canal bank but which may not be directly related to a lack of elbow grease.

 

 

 

 

 

 

 

 

 

 

 

 

PS: I agree, I took a scrubbing brush to my green and mouldy yogurt pot the other day and it now looks as good as new. Even duck poo on teak decking was easily scrubbed away.

I was ay one time a marine valet, had to bring floating GRP gin palaces back to show room condition.

Starbrite boat-wash-in-a-bottle will do the job. Damp down the surface to br cleaned and then using some sort of spray bottle mist over the work are, allow to soak a bit then scrub and hose off. This method works for all canopies cratch civets etc.

For areas such as cabin tops that are painted and sanded use Starbrite Foaming Deck Cleaner, follow the instructions on the bottle.

These chemicals are safe to use quick and effective.

Always makes me smile when I see people laying out canopies etc on the ground and scrubbing them so much hard work!

Just wet the canopy, spray with Boat wash, soak for a fee minutes, scrub, hose off and watch the green wash away.

I used and still have a hard bristled extending broom to scrub with.

As for pressure washer well we never ever used one. Causes to much damage
