Stains on fabrics – Pokost
Pokost. Fresh varnish stains are removed like this, like grease stains, for the varnish contains oil, especially linseed oil. A stain remover or carbon tetrachloride is suitable for removing varnish stains. If the use of these solvents does not bring the desired results, make a mixture of stain remover, chloroform, ether and carbon sulfide. After the stain is soaked in this mixture, the stained area should be washed with gasoline. Older varnish stains should first be softened with turpentine, by carefully removing the hardened crust from the surface of the stain. Great care is recommended when cleaning natural silk stained fabrics with varnish (friction is especially harmful); however, it is also possible to try to remove these stains with all the solvents mentioned. Varnish stains on artificial acetate silk are removed with carbon disulphide or turpentine, and then gasoline, but never with chloroform. Products made of polyvinyl chloride fibers can only be stained with gasoline.
