cleaning vinyl siding
when cleaning my neighbors vinyl siding using zep vinyl siding cleaner, i did not rinse it off well enough in a couple of spots which i noticed the next day. So I tried re-rinsing and that didn't work so i added more cleaner and re-rinsing and that didn't work. So I tried scrubbing with a soft brush,the chemical and again with my pressure washer and the stains left by the cleaner itself will not come off? HELP !!! My neighbor is not happy and wants the stains removed!!!
