I built my garapa deck 14 years ago. Stained with TWP. Used Restore-A-Deck to clean and brighten the first time I cleaned it. A number of years ago I was trying to get it clean to refinish it, but I simply could not get all the black (presumably mold?) off of it and kind of gave up, just letting it go.
This year I decided I really want to get it cleaned up, but I'm having the same problems. I have tried sodium percarbonate stuff (in hot water),TSP, and chlorine-based stuff (Cabot Problem Solver Wood Cleaner #8002) all at pretty high concentration and together with scrubbing and power washing. Still can't get it clean. (Haven't bothered with brightening until I can get it clean.)
I used some Ipe pieces for accent and they are fine. Last resort is to sand it (ugh), but I really hate to do that.
Pictures show what it looks like after attempts at cleaning. Note the Ipe piece is on the left. Rest is Garapa.
Any suggestions?

Thanks. I've been hesitant to stain it since I didn't want to stain on top of mildew. If it is discoloration, then I guess I could stain over it?? What's the best way to be sure it is not mildew?

I tried all different cleaners and nothing made any difference , I sealed it with oil 2 weeks before laying , strange thing is the boards that we haven't layed yet look fine its just the ones that are layed . Looks really impregnated , sanding looks to be the only fix but how do I stop it from coming back ?
