    Doug Johnson posted a question in Residential Pressure Washing

    What is the best way to clean 20 year old aluminum siding? It goes without saying, it is pretty chaulky. Do I keep the pressure off? What about chlorine? Do I remove the chaulk or just the dirt and mildew? Thanks for any help. Doug

    Can I use bleach or S/H @12% to remove mildew? X-jet it on and rinse it off? Maybe a little surfactant ?

    local awning dealer and get samples and test them. I did and tried everything from 12% sodium hypoclorite, oxalic acid, sodium hydroxide gutter zap and anything else I could think of. All straightout the pail. Didn't hurt the samples at all even after leaving on overnight. This was vinyl like is used for back-lit awnings. I don't no about fabric although I have washed them with sodium hypo and the cleaned up fine. Make sure to rinse really well and don;t let it dry.
