Schaeffer Citrol is without a doubt the Best Cleaner we have found for removing tire marks and sticker glue. Far superior to any hardware store product. Citrol is a safe, biodegradable degreaser with astonishing cleaning power. It outperforms solvent, solvent emulsion and alkaline cleaners for removal of heavy greases, carbonized oils, gear lubes, grease buildups, oily deposits, tar and bituminous deposits.  One of the few solvents tough enough to remove stubborn printer's ink.
