Acetone Commercial Grade-25 Ltr

Glycerine. Glycerine is sold generically in pharmacies. It is used in the preparation of the wet spotter, which is used to remove many kinds of stains.

Oxalic Acid. Effective in treating ink and rust stains, oxalic acid crystals may be found in pharmacies or special-ordered from them. Before using the crystals, you must dissolve them in water (1 tablespoon crystals to 1 cup warm water). You may also be able to purchase liquid oxalic acid at hardware stores, where it is sometimes sold as wood bleach. Pretest the solution on a hidden corner before using it on the stain. Moisten the stained area with the solution. Allow to dry, then reapply, keeping the area moist until the stain is removed. Be sure all traces of the solution are rinsed out. Caution: Oxalic acid is poisonous. Avoid all contact with the skin and eyes and wear rubber gloves and other protective clothing when working with it.

Sodium Thiosulfate. Sometimes available in crystal form at drugstores and photo supply houses, sodium thiosulfate is also known as photographic "hypo" or fixer. Although considered safe for all fibers and harmless to dyes, it should be­ tested on an inconspicuous area of fabric before use. Handle carefully, as sodium thiosulfate can cause irritation to the eyes, skin, lungs and digestive tract.

Turpentine. Turpentine is commonly found in paint and hardware stores and in art supply houses. Most often used as a thinner for oil-base paints, it is effective on paint and grease stains, but it must be used carefully. Caution: Turpentine is flammable and poisonous. Observe all label precautions.

Vinegar. Only white vinegar should be used for stain removal. Cider and wine vinegar have color that can leave a stain. Vinegar can be purchased at grocery stores and pharmacies. It contains a 5% acetic acid solution and should be diluted if you must use it on cotton or linen. Vinegar is safe for all other colorfast fibers, but can change the color of some dyes, so always test its effects on an inconspicuous area first. If a dye changes color, rinse the affected area with water and add a few drops of ammonia. Rinse thoroughly with water again.
