When washing houses, I find the only way to get the vinyl clean many times is to get the nozzle close to the area being cleaned. My concern is water getting behind the siding/fascia etc. and causing damage. Is it possible foe water damage to occur? I think it is impossible to wash a house without getting water behind the vinyl.I use 3000psi, 3.5gpm cold water. I was using a 40 degree nozzle, but am trying a 25 degree tip. I usually use a mixture of bleach and water to kill algae/mildew. I have had cases where I could not remove dirt by simply washing-I had to brush then rinse. Any input as to proper washing techniques. Also, will TSP hurt glass?
