Stain classification starts with stains that require similar treatment and are easiest to remove if treated promptly and correctly. Stains that require two-step or special treatment are listed last.

After treating the stain, clean with warm (not hot) water, rinse, and absorb with paper towel. If stain remains, retreat for an additional 10 minutes, then Rinse and absorb. or Call a professional.

Clean with cold water, and a mild detergent like sodium carbonate (washing soda).

Fresh protein stains can be removed by first spraying & absorbing with a solution of cold water and sodium carbonate. These stains contain other ingredients besides protein, but it needs treatment first.

Caution: If hot water is used first, it cooks the protein, causing coagulation between the fibers in the yarns of the carpet, making the stains more difficult to remove. If protein stains are dried or old, scrape or brush off crusted matter (if any), then soak with cold water using a detergent or an enzyme product.

Tannin Stains
Cleaning Solution: Hydrogen Peroxide & ammonia solution or sodium percarbonate. Do not use soap.

Fresh tannin stains are usually removed by Oxidizers and cleaning with hot water. Caution Use of soap (bar soap, soap flakes, or detergents containing natural soap) will make a tannin stain permanent or at least more difficult to remove.

Old tannin stain needs special treatment for more complete removal. Call a professional.

Oil-based Stains
Cleaning Solution: Use heavy-duty detergent with hot water, and/or a solvent like Orange oil (citrus) or liquid Dry cleaner.

Oil stains can be removed by pretreatment with a heavy-duty liquid detergent, an aerosol petroleum-based solvent pretreatment spray, or a pump-type detergent-based pretreatment spray. If these products are unavailable, you can use a powdered detergent that is mixed with water to make a runny paste and apply that to the stain.
The heavy-duty liquid detergents or aerosol sprays are more convenient and effective.

Work the full-strength heavy-duty liquid detergent into the stain or spray with the pretreatment product, then absorb with paper towel Rinse using hot water in spray bottle & absorb with paper towel. Repeat this treatment if removal is incomplete the first time or Call a professional.

Dye Stains

Needs oxidizing agent or color remover.

Dye stains are very difficult to remove. Call a professional.

Combination Stains

Two step treatment :

1. Remove oily/waxy portion
2. Remove dye portion using and oxidizer

Combination stains contain a variety of ingredients, but these stains usually have an oily/waxy component and a dye or pigment component. Use the procedures recommended for removing oil stains first.

Step 1 procedure depends on whether stain is in Group A or B as follows:

Group A.
Cleaning Solution: Spray or sponge with drycleaning solvent, then spray with a solution of heavy-duty liquid detergent and warm water and absorb with paper towel. Call a professional.

Group B.
Cleaning Solution: Clean with solution of sodium carbonate and warm water.
