How can i get black Mildew of my garden furniture?
I bought the garden furniture in the summer last year 2 benches 2 chairs and a table it is lage and was expensive.So when the winter started to come in we covered it in a large ground sheet thinking we were protecting it.Then we had high winds and the wind blew the cover of (we are glad it did)and we found that the water or whatever had got inside and black mildew had got into the wood.Is there anything at all that will clean it up
