Stains on fabrics – Tar
Tar. The hardened top layer of tar should be softened with a small amount of margarine or butter, then remove it with a blunt knife or scrape it lightly. This treatment is repeated several times until the deeper layers of the tar stain are softened. After removing the hardened layer, tar and grease residues are removed from the fabric surface with a solvent, e.g.. carbon tetrachloride, liquid for removing stains, gasoline or turpentine. If we use turpentine, additional rubbing of the stained area with gasoline is necessary. You can also dampen the tar stained area of the fabric with a fairly large amount of stain remover and leave this substance on the fabric surface for some time. (a well-absorbing foundation is essential), then apply a mixture of olein and stain remover. If after this treatment there are still traces of tar stains (traces can almost never be avoided, because the tar dyes the fabric very intensively), it should be moistened with olein and carbon disulphide. Finally, of course, the olein must be removed from the surface of the fabric, using a suitable solvent, preferably gasoline. Turpentine and gasoline are best suited for removing tar stains from acetate and polyvinyl chloride fabrics.. When wet cleaning tar stains, turpentine is first used, then the detergent solution, and finally - rinsing with water.
