i'm looking into drive cleaning as i seem to be getting quite a bit of interest from my customers. i currently clean windows with water fed pole so i already have a very large customer base to target.
was looking for some advice from guys that have been doing this line of work. would like to know what flat surface cleaner i should buy, pressure washer (psi/flow rate) whether should invest in wet vacuum and any other equipment that you pro's feel i might need.
many thanks jon
