How to get algae off fences
ABS Fencing shared a list of do's and don'ts when it comes to cleaning green algae off your fence. Don't use household mould or mildew remover sprays as these are generally intended for use on hard surfaces indoor.
Don't use bleach in the garden, it kills a lot more than the mould.
Don't try sanding back the top surface of the wood, as algae will just regrow back.
Don't bother with power hosing – that only opens up the timber grain and allows more water inside, making the problem worse down the line.
Do use white vinegar mixed with hot water in a spray bottle and work it in with a brush, leave for 30 mins or more, then hose down.
Do repaint when dry with good quality fence paint.
It is described as a practical cleaner that will rid your home of mould and mildew, making your home safer and cleaner.
It's also said that the spray visibly removes mould in 2 minutes and prevents spore regrowth so that your surfaces stay clean and mould and mildew are kept at bay.
However, other posters came up with alternative suggestions and one member said: "Bleach and water does the same thing!!"
"I've seen ppl use Pool Chlorine tablets in a spay bottle," said another.
"That algae would come off with some hot water and a scrub. Or there are more eco friendly products that would do the same job."
While another explained: "Better of jet washing then using an oil stain like decking on it the green shouldn't come back."
"White vinegar kills mould so that could be an option. X." added another group member.
