Mould is the scourge of teak decks - is this an answer?
Some while ago I asked about how to clean green decks short of the usual 5 or 6 hours kneeling and using a Scotchbrite pad. I’ve had several suggestions, some of which I’ll be trying over Easter and will report on in due course.
First are a couple of proprietary products, Patio Magic by Brintons, which is described as being ‘MMC concentrate’ and Polycell Mould remover.
Susie Burrall suggests white vinegar and water, mixed 1:2 and advocates eating chips at the same time so you don’t notice the smell whilst Gordon MacKenzie recommends dishwasher powder dissolved in a bucket of water. Watch this space.
