For pitch or hardened linseed oil, yes, but only as a first choice on fringe or a flatweave. I'd recommend a gel solvent first if the pitch was in the nap of a rug just because it would be easier to rinse. Some alcohols will also work, but may dissolve the surface of a pitch blob and flash off like a volatile solvent. If the pitch is heavy turpentine will make faster work of it than alcohol.Brian,,, you love turpentine.. don't you!!?
