Impregnators
The surfaces of both textile and leather articles are treated with a modern impregnating agent to make them resistant to dirt and water. Cleaning is easy, and water drops roll off. After textile clothing has been machine washed or dry cleaned, the impregnation should be reinforced and refreshed with a commercial textile proofer. A leather impregnator should be used on leather clothing.
