Hi
We recently cleaned the inside windows of an office building using a cherry picker. The main hydraulic pipe burst on the machine spewing hydraulic oil all over the floor (granite tiles) we mopped it all up using paper towels and then mopped with a light detergent. Unfortunately there seem to be tire marks from the cherry picker embedded in some of the tiles. The customer has complained and i was wondering if anyone knew of a way of removing the marks. The tiles look sealed but are dull in apperance they are swept, mopped and buffed regulary. Any help would be appreciated.
Thanks
Jonathan
