Does anyone know how to get mildew, mold, gungo or whatever it's called off a plain concrete deck? It is really bad this year; the 'tan lines' where the tarp was is just awful looking.
I tried a strong clorox bleach solution and scrubbing diligently with a long handled deck brush, but getting poor results.
Advice needed. Thanks in advance.
