Fresh stain adjustment
This plan prioritizes speed and blotting because fresh stains are easiest before pigment spreads or sets.
Treat today
Oil and egg emulsion — absorb excess with baking soda first, then degrease with dish soap.

Grab first
- 1Cover the stain with cornstarch or baking soda and let it sit 30 minutes to soak up the oil. Act before it dries. Because this is colored fabric, test solvents or peroxide on a hidden inside area before treating the visible stain.
- 2Brush off the powder, then squeeze dish soap (like Dawn) directly on the stain and rub it in
- 3Wash in the warmest water safe for the fabric and air-dry — check it's fully gone before the dryer
Do not: put it in the dryer before the stain is gone — heat bonds oil to fabric permanently.
Safety note
Blot first. Rubbing pushes pigment deeper and makes the stain wider.
Safety note
For colored fabric, test any solvent or peroxide on a hidden inside area first.
Why this order works
Absorb or blot first so the oil stops spreading. Surfactant comes next because it surrounds the oil so water can carry it away.
Mixed stain? Deal with any protein part first using cold water, then treat the pigment or oil. Heat sets protein permanently.

Why this works
Oil-based stains are hydrophobic lipid molecules that repel water and bond tightly to fabric fibers through non-polar interactions. Dish soap acts as a surfactant — its molecules have a water-loving head and an oil-loving tail that surround the lipid droplets and allow water to carry them away in the rinse. Synthetic fibers like polyester and nylon are thermoplastic: heat above roughly 60°C can partially melt the polymer surface and trap pigment molecules inside, setting the stain permanently. Cold water and low-heat drying are essential regardless of the stain type.
