Hello,
I just cleaned my deck and I noticed that there are black spots lefts on the wood. I was wondering what they are and if I can remove them
Thanks im advance!
Looks like old stain that needs to be stripped. Brighten after.
It is not an old stain as there is one side of the deck that has never been stained and it has the same black spots.
Might want to try and reclean and then brighten the wood after.
