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
- 1Sprinkle cornstarch on the stain and let it sit 20 minutes, then gently brush it off. Act before it dries. Because this is colored fabric, test solvents or peroxide on a hidden inside area before treating the visible stain. Use less liquid and less rubbing than usual because this fabric is sensitive.
- 2Dab with a cloth and a tiny drop of dish soap — do not rub
- 3Rinse gently with lukewarm water and lay flat to dry
Do not: soak rayon or wring it out — it tears and distorts when wet.
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. Rayon is a semi-synthetic fiber made from regenerated cellulose that weakens significantly when wet and distorts easily from agitation or heat. All treatments should use gentle blotting rather than rubbing, and the garment should be laid flat to dry to preserve its shape and dimensions.
