Does anyone have any methods to remove what seems to be black rubber grease stains on new carpet. It has come from the black stoppers at the back of a portable piano.
Hi, try wiping the marks with orange oil or eucalyptus oil or tea tree oil, all will loosen tar and other marks,Try it on a piece of the carpet that can't be seen first to check for adverse effects. Use a clean white cloth for this. Hope this works for you.
