Hey, y'all-I'm back! Been brushing up on black mold treatments & see that H2O2, baking soda & potassium bicarbonate are all suggestions. I'd like to know what strength H2O2 to use & how strong a solution for the other 2 choices given. Would like to get this thing taken care of in time to refinish table for next year's patio time. Any info appreciated. And Merry Christmas to all.
Additionally, have been told that this wood began to show this black stain about 6 mths ago, & even after prolonged periods of no rain, will have what appears to be water beading up on the surface. Thanks, Northwesterner, I'll try 3% H2O2-do I just apply & let sit or what?

Have you tried regular strength (3%) hydrogen peroxide to see how it works?

What you have is regular green mold that has died and turned black. What most people (not organic) do is spray with the deck or fence reconditioners. Those are chemical acids and you might not want to go that route.
