⚠ Safety Warning

Test any cleaning solution on a hidden seam or inside hem first. Check for colorfastness before using any bleach or hydrogen peroxide. Avoid heat until the stain is completely gone — heat sets stains permanently.

🔬 Why This Works

Oil — this oil-based stain resists water and needs a degreaser or cleaner to break it down. Cotton fabric absorbs liquids quickly and holds onto stains deep in the weave, so oil works its way into the material. The treatment needs to reach the stain where it's hiding, not just clean the surface. Dish soap or a degreaser breaks down the oil so it becomes water-soluble and can actually be rinsed away.

👔 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: Good news — we’ve treated the oil on your garment. Oil-based stains repel water, so regular washing alone usually can't remove them.
