    a friend said i have 'GUNGO'!

    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.

    Sounds like it's time for the pressure washer!

    Yep, what Bama said. After pressure washing it. consider puting a concrete sealer on it. It will keep the dirt out of the poors in the concrete and make it easier to clean next time.

    After buying 3 of them I now consider those cheap electric pressure washers disposable, the last one from Lowes lasted less than 2 hours, upon failure I found casting sand from the pressure pump in the water passages. I currently have a gasoline powered one from Sears, bought it this fall as a last years floor model clearance for about $180, original price $399.

    When you were done scrubbing with the bleach, did you rinse it off? Let it remain on the deck.

    thank you all for replies...you're all so prompt and kind!
    i went ahead & bought a $100 pressure washer from homedepot, figuring if it breaks, i'd bring it back (homedepot is terrific for refunding returns without any harassment).
    ..but anyway, it works very nicely . . better than i expected for sure. it'll take a few more sessions b4 i'm done . . . & will let y'all know if it breaks . . hehehe.

    I think I have the same problem. After taking the cover off, there were clear lines where it is lighter where the cover laid. Is that how yours was? Do you have before/ after pics?
