Removing mould and mildew from slippery decking. Getting rid of mould and mildew is a simple task. Get yourself a bucket of hot, soapy water and a good hard yard brush and scrub away a square metre at a time.
Give the planks a good clean, making sure you get right into the grooves and between the planks. Once you have rinsed the whole area a couple of times, leave it to dry – maybe overnight. Then, apply a clear decking wood preserver or sealant for a nice-looking, long-lasting finish. Laois Garden world stocks both Decking preserver and sealant in our shop.
