My decking has been down for two years now but looking sad with the ravages of the weather. I am going to treat it before the bad weather sets in but can anyone tell me the best, and cheapest, way to clean off the slippery green mould/algae that seems to have taken hold. I do have a pressure washer to use but people tell me that rasies the grain on the wood and anyway we're on a hosepipe ban!

Plain ol' household bleach in a bucket of water and brush or mop it on to kill the algae. Let it set for a while and then rinse it off. bingo, it should be in good shape after it drys thoroughly to put a sealer on.

What makes it slippery. If it ain't ice and snow, then it is MOLD/SLIME which attacks the board to break it down to become soil again. It is the process of life. Sooner or later we or it becomes fertilizer. You can slow down that process by using a pressure washer or an IED , but since most of us don't have those types of devices sitting around, use an empty ice cream pail(gallon type) and put in a couple cups of bleach. Then go out with a paint brush and paint the boards with copious amounts of bleach and if you have it put a sheet of plastic over it so the rain or the garden hose does not wash it off right away. Give it a day for the bleach to soak into the wood and then take the plastic sheeting away.

Don't use bleach, where's that going to end up!! Go to a hardware shop and get some KEW/Karcher/Altro 'Green Cleaner' it will loosen the algae covering in 30 mins or less and then you can simply wash it off. You could use the pressure washer on low pressure without damaging the wood surface, but if you have hosepipe ban!!!! even though the washer will probably use less water than endless buckets!

They dont tell you about this problem when you buy the stuff, or that it will rot and youll have to pay zillions of pounds to get it removed!! Try an expensive quality patio cleaner and a stiff scrubbingbrush. Wear thick rubber gloves, and old clothes, and kneel on a thick pad inside a plastic bag- you really dont want that stuff on your skin. wash it all off with plenty of water, making sure your kids and pets are kept off it, and dont let it get onto your garden as it will murder everything in sight. The moral to this little tale? Dont deck, garden instead.Dont waste money on a pressure washer to remove algae; it will start to come back as soon as you turn the water off!!!

rub it down with some wire wool till the mould is gone and then rub down again with a cloth and some teak oil. to get the best out of a deck, although its usually pressure treated, I always treat before building. then its just a case of once a year, mid - late autumn, easy maintenance with the oil or stain.

I'm not sure how big your decking is, but how about using a scraper, put some sand down first or some salt or something that will cling to it, then use a decorators scraper or something similar to get it up.

Power wash it first then go to a lumber yard and buy deck sealer to use on it. Raising the grain does not hurt if you seal it properly.

Looks like you'll have to use elbow grease, get a stiff bristle broom, large bucket, hot water with bleach and scrub down; like they do on ships.
