Have a 4 bay auto shop that I want the concrete floor cleaned. Dont want anything too deep just want the surface brightened up and hopefully get some of the oil at the same time. Was thinking a buffer and citrus cleaner. Can only give you 2 bays at a time so 1/2 the shop keeps operational. We will move any items for you that arent attached to the floor. Regular working hours. Night work not necessary. Total sqft in the 4 bays is about 2000 sqft. Send me your pricing, name and number. Photos might help too. No Contractors that will sub it out.
