Dear fellow powerwashers, my question is as follows: I recently powerwashed vinyl siding on a pretty hot day, using ZEP all purpose cleaner on a 1:8 ratio. Most of the siding looks great except for the south side which shows some swirls caused by the ZEP or the powerjet. I am really not sure . Is there anyway to remove these swirls? I tied powerwashing it a second time just with water. Not much improvement. Thanks for your input. Otto Alber * New Hope Window Cleaning Service
