I have stains from rubber backed rugs on my bathroom floor, is there any way of getting them off.

If your floor is a vinyl product there isn't much you can do about it except keep replacing the rug. Rubber backed rugs and vinyl flooring do not get along well together. If they are vinyl tiles you can always try to replace them if thet aren't too old and you can still find the product. We had this happen once and then read the warning on the tile box not to use rubber backed rugs on the floor. Must some kind of petroleum conflict.
