Hey all, long time pressure washer here and have recently got into mostly residential window cleaning. I’ve been requested to bid on 230 of these windows. They haven’t been cleaned in over 14 years and wfp & squeegee wouldn’t clean them, only my steel wool. Im wondering how cleaning a project this big would be possible? Someone told me soft washing one restore & quickly rinsing then WFP will work. Could anyone tell me if this is true, or other alternatives?
Thanks!
