Hi Guys,
One of the offices I clean is a motor oil distribution warehouse, they obviously have spills and over the months their new carpet has stains throughout it and traffic marks from where the ware house staff pop into the office.
The carpet is luckily a dark colour which is tiled and very short pile. Standard office carpet on what looks like black bitumen.
Have many of you had success in removing oil from office carpets, my worry would be about using a solvent and damaging the backing, what is the best pre spray / rinse you have found, I am a clean smart guy but open to any other products.
