Customer has had a chip pan spill on their communal staircase cheap rubber backed nylon carpet oil keeps re-appearing any ideas?

might seem a bit far out but what about relying on the good old surfactants science. Washing up liquid was designed for seperating oils/grease from cutlery. Perhaps it could work in the same way that citrus gel works on sudocream (have you thought of ctirus gel). Either way the it;s got to be about seperating the oil from the fibres then rinse rinse rinse (then probably repeat repeat repeat). Probably sounds like a load of boll$%ks but make sense to me. Especially after 3 cans of Stella (or ars&(ole) as my wife calls it.

Steve,

I had this problem a few years back, a customer had dripped cooking oil all along the hallway from the kitchen. I went back to clean it about 3 or 4 times before it finally went. In that time I used several different cleaning agents, Micro-splitters, Eco Spotter, Blitz. With each one it would be clean but would re-appear weeks later. I put it down to having soaked into the backing and just kept wicking back up. I did not charge for the re-cleans but gained a good regular customer which has paid for itself many times over.

I guess if you could lift the carpet to clean the back etc you may cure the problem, but that is not always possible. Or if you have one of those spot lifters you could flood it with detergent and extract out, I probably would have used this method if I had one at the time.

rubber backing acting as a sponge by the sounds of it,
flood it with champion and then rinse ? a lot!
