Sprinkle baking soda or cornstarch on the stain. Wait 5 minutes.

Brush off the powder with a clean white cloth.

⚠ Safety Warning

Test on an inside seam or hidden area first — delicate fabrics can react unpredictably. Never use bleach, enzyme cleaners, or hot water. Use cold water only. Handle gently — rubbing or wringing damages the fibers. Lay flat to dry.

🔬 Why This Works

Grease — cooking grease is a thick oil that coats surfaces and resists water — water alone won't break it down. Wool absorbs grease oils into its delicate fibers. The oil bonds with the natural oils already in the fiber, and harsh solvents risk damaging the material. Cold water and gentle cleaning agents are the only safe approach — anything stronger risks destroying the fiber along with the stain.

👔 Professional Treatment

This is what your dry cleaner would do. Professional methods use commercial-grade solvents, specialized spotting boards, and controlled dwell times. If you're a dry cleaning operator, these are the steps for your counter reference.

Apply POG directly to the oil stain. POG is a volatile dry solvent with strong affinity for lipids — it dissolves oil droplets on contact. Tamp gently and blot with absorbent cloth. For delicate fabrics, use VDS (Volatile Dry Solvent) instead.

POG (Paint Oil Grease remover) 5-10 minutes Solvent extraction — dissolves and lifts oil from the fiber dry side

If POG plateaus, apply amyl acetate for stronger solvent action. Amyl acetate is especially effective on older or polymerized oil stains. Blot with clean absorbent cloth between applications. Never use on acetate fabrics.

Amyl acetate (banana oil solvent) 3-5 minutes Secondary solvent — targets stubborn or polymerized oils dry side

Apply NSD to emulsify any remaining oil micro-droplets and remove solvent residue. The detergent surrounds oil particles and allows them to be flushed away. Rinse thoroughly with cool water.

NSD (Neutral Synthetic Detergent) 5 minutes Detergent flush — emulsifies remaining micro-droplets of oil wet side

Apply diluted acetic acid to restore fiber to its natural state. Blot dry with clean cloth and allow to air dry.

28% Acetic acid (diluted 1:10) 1-2 minutes Final pH restoration wet side

Customer explanation: This one took some work — the grease stain on your garment needed a multi-step treatment to break it down. Grease repels water, so regular washing pushes it around rather than removing it. The treated area may continue to improve over the next day or two as it fully dries.
