Scrape off as much excess tar as you can using a dull-edged tool such as a paint stirring stick or a non-serrated, dull butter knife. Knives can scratch tile, so use a light touch.
Apply a thick layer of butter or mineral oil on the tar stain.
Scrape the tile again with the dull scraping tool. Do not wipe off the oily material at this point; work it into any tar that hasn’t softened.
Wipe off the oily residue and loosened tar with a paper towel.
Apply more butter or oil to the tile if any tar remains. Let it sit for a few minutes, then scrape off the remainder of the stain.
Dampen a clean rag with degreasing floor cleaner.
Wipe the oily residue with the cleaner, turning the rag frequently, until the oil is dissolved.
Rinse the rag in plain water, and wipe the floor to remove all traces of cleaner.
Apply masking tape around the perimeter of the tar stain. This helps prevent spreading the stain.
Scrape off as much tar as you can with a wooden scraping tool such as a paint stirring stick or a wooden craft stick; metal tools can permanently scar linoleum.
Dampen a white rag with full-strength mineral spirits or turpentine. Solvents can cause rags with any color to deposit stains on the linoleum.
Wipe the tar inside the taped outline with the damp rag. Turn the rag frequently to reveal a clean side, which helps avoid redepositing or spreading the tar stain. Switch to a fresh rag as necessary, if the first one becomes covered in tar. Continue until all tar residue is removed.
