Allow mud stains to dry and brush carefully before any other treatment is used. Sometimes no other treatment is necessary. The following agents are satisfactory:

1. Soap and water, as in ordinary laundering, for washable materials.

2. Alcohol. Sponge the stains with alcohol.

3. Water. Sponge the stains.

4. Cut raw potato. For black silks of firm weave, after brushing, rub the spot with the potato. This leaves a thin film of starch on the surface of the cloth, which can be brushed off when dry. This treatment is too harsh for any but rather smooth, firm goods and leaves a spot on all but black materials.
