I have a potential customer that wants me to pressure wash 13 forklifts twice a year. He said that he normally just goes to Home Depot and rents a machine for the day, but he now wants to hire someone for the job. I have absolutely NO idea on what to charge for this. Has anybody on the forum ever done this kind of work? I would imagine that they arent filthy dirty since he cleans them so often. These are standard gas Clark forklifts used for lifting pallets of paper. Please help if you can as I need to get a bid to him soon.
