Sponge (the method of using a dampened pad to apply light strokes, moving outward from the center of the stain) the area with a dry-cleaning solvent such as Afta Cleaning Fluid. Then apply a dry spotter. Tamp (the method of bringing a brush down with light strokes on stained durable fabrics and materials) or scrape (the method of using a dull tool to gently lift off excess solid or caked-on stains) to help loosen the stain. Flush (the method of applying stain remover to loosen staining material and residue from stain removers) with the dry-cleaning solvent. If stain persists, apply amyl acetate and tamp again. Flush with the solvent and allow to dry. If stain still remains, sponge stain with water and apply a few drops of white vinegar. Tamp again. Apply a wet spotter and a few drops of ammonia (do not use ammonia on silk or wool). Tamp again. Allow to dry. Sponge with rubbing alcohol and pat with an absorbent pad dampened with alcohol (do not use full-strength alcohol on acetate, rayon, or triacetate). Allow to dry.

How To Make Wet & Dry Spotters
Dry spotter:
To make a dry spotter, combine 1 part coconut oil (available at pharmacies and health food stores) and 8 parts liquid dry-cleaning solvent. This solution may be stored if the container is tightly capped to prevent evaporation of the solvent. Mineral oil may be substituted for the coconut oil, but is not quite as effective.
Caution: Dry-cleaning solvents are poisonous and may be flammable.
Wet spotter:
To prepare a wet spotter, mix 1 part glycerine, 1 part white dishwashing detergent, and 8 parts water. Shake well before each use. Store wet spotter in a plastic squeeze bottle.
