Do any of you guys clean gas stations, the concrete. Is it possible to do this with a cold water pressure washer? get the gas stains and stuff up? also, i am just getting into this business and today i called many places to try to get work, i called most of the carlots and no luck. Anyone got any suggestions on how to get started to get my name out there, as in get some steady work. certain places etc. any help would be appreciated. Thanks.
