Sweat on Wool

Fabric color
Fresh stain adjustment
This plan prioritizes speed and blotting because fresh stains are easiest before pigment spreads or sets.
Treat today
Salt and protein oxidise over time, yellowing the fabric. Treat within hours.

Grab first
- 1Blot up the excess, then rinse with cold water. 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 on a stain remover spray (like OxiClean) and gently press it in with your fingers — let it sit 10 minutes
- 3Rinse with cold water, gently squeeze out the water, and lay flat to dry
Do not: use hot water or put it in the dryer — wool shrinks badly.
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
Cold water comes first because heat denatures protein. Enzyme or detergent work is safest only after the protein has been kept loose.
Mixed stain? Deal with any protein part first using cold water, then treat the pigment or oil. Heat sets protein permanently.

Why this works
Protein stains contain amino acid chains that denature and coagulate above 40°C, permanently cross-linking with fabric fibers — which makes cold water the single most critical first step. Enzyme-based cleaners (proteases) chemically sever the peptide bonds in the protein structure, dissolving the stain from the fiber without mechanical damage. Silk and wool are protein-based fibers that share the same amino acid chemistry as protein stains, so alkaline detergents and protease enzymes risk attacking the fiber itself alongside the stain — this is why pH-neutral cleansers and cold water are non-negotiable on these materials.
When to call a professional
Wool is a delicate protein fibre. If the stain has spread, the fabric has shrunk, or home treatment has not shifted it after two attempts, a professional dry cleaner using specialist solvents will get a better result without risking further damage.
