We are making the house we are in liveable for 18mt5hs, and pulled out an old oil heater. Unfortunately this has leaked along the floorboards under the carpet. It was stood on and has now come back up through the carpet I have tried carpet shampoo, then nappysan direct when I thought it was just dirty footprints, and then turps when I realised what had happened. I have now stood on sheets of doubled paper and sopped a lot of it up, however the turps didnt shift the stain. It is good quality carpet in good condition and has taken the beating I have given it over this so will stand some more drastic action, however we dont care abvout it and actually have another piece of ordinary carpet we could replace it with. This is a lot of work though and would prefer not too. Any suggestions of how to clean this stained area up a bit. Do you think bleach would lighten the stain? Anyone??
