My fence is in not bad condition meaning few grey area except where the sprinklers hit the fence, and I have heard and read that the type of pressure washer that you rent have too much PSI and can actually damage the fence? If this is the case is their a fence cleaner that some of you have used and could recommend? Also here in Texas like much of the south our temperatures are in the 90's so am wondering if I should wait until cooler weather to clean and stain the fence? I have decided to use the Armstrong-Clark stain brand. If this question has been answered somewhere else just let me know. Any help would be appreciated.
