Grass contains both chlorophyll (a green coloring matter found in plants) and tannin (a yellow-to-tan colored substance found in plants).
Chlorophyll is removed with amyl acetate; tannin is removed with acidbased agents such as tannin formulas or 28 percent acetic acid. The procedure for removing grass stains is as follows:
Proceed to the next step only as needed and, as with any stain removal procedure, test for colorfastness.
- Saturate the area with volatile dry solvent.
- Apply amyl acetate and tamp.
- Flush the area with volatile dry solvent and dry.
- Flush the area with steam or water.
- Apply neutral synthetic detergent. Tamp and flush with steam or water.
- Apply a tannin formula or 28 percent acetic acid with neutral synthetic detergent. Tamp and flush with steam and water.
- Apply a general formula. Tamp and flush with steam and water.
- Apply rust remover. Do not tamp. Flush very thoroughly with steam and water.
- As a last resort, apply an oxidizing bleach only after testing thoroughly for colorfastness. Flush with steam or water.
After the stain removal procedure is completed, drycleaning or wetcleaning may be necessary to remove any ring or circles from the stain removal agents.
