Repairing a furnace or spreading out a bathtowel on fuel-spoiled sand are situations where tar or heating fuel can stain your fabrics. Alas, these stains are generally very visible and seem difficult to get rid of. Our cleaning advice :
Remove as much of the tar stain as you can with a spatula or a spoon (if necessary, soften them with a fatty product such as butter or margarine) then dab the remaining spots with benzene and sprinkle diatomaceous earth (or diatomite) or talcum powder and then brush or vacuum.
Turpentine can also be very effective
– On man-made fabrics, dab the stain with a cloth soaked in lemon water or benzene, or white spirit. Rinse & dry.
