A guest returns from a beach club at 2am. The white linen shirt she hands you has red wine down the front, sunscreen on the collar, a smear of make-up on the shoulder and a mark that could be grass or could be pesto. If you treat that shirt as one problem, you will fail. It is four problems, in a specific order, and the order is the whole skill.
The stain taxonomy
| Class | Examples | Removed by | Never do this |
|---|---|---|---|
| Protein | Blood, sweat, egg, milk, vomit, grass | Cold water first, then protease enzyme (on non-protein fibres) or a neutral protein spotter | Heat. Heat coagulates and sets protein permanently |
| Tannin | Red wine, tea, coffee, fruit juice, beer | Warm water, mildly acidic tannin formula, oxygen bleach | Do not use soap/alkali first — it sets tannin |
| Oil / grease | Sunscreen, body oil, butter, make-up, engine grease, lipstick | Solvent or dry-side spotter first, then a non-ionic surfactant/degreaser, then wash warm | Do not start with water — water cannot lift oil |
| Dye | Ink, red wine dye component, grass chlorophyll, self-tan (DHA colour), curry, mustard | Reducing/oxidising dye removers, alcohol, oxygen bleach, sunlight | Do not scrub — you drive the dye deeper and spread the ring |
| Combination | Most real stains — sunscreen (oil + dye + zinc), lipstick (oil + dye), gravy (protein + fat), salad dressing (oil + tannin) | Reverse-order treatment | Do not treat as a single stain |
Reverse-order treatment
For a combination stain you work oil side first, water side second:
- Remove the oil/grease component with a dry-side (solvent) spotter.
- Flush the solvent out.
- Then attack the protein/tannin/dye component with wet-side chemistry.
- Rinse and neutralise before drying.
If you go water-first, the water swells the fibre around the grease and locks the oil in.
The spotting sequence
- Identify: what is it, how old, what fibre, what colour?
- Test: every agent on a hidden seam, every time.
- Work from the mildest agent up. Cold water, then warm, then surfactant, then enzyme, then solvent, then bleach. Never start at the top.
- Work from the back of the stain, pushing it out the way it came in, over an absorbent white pad.
- Tamp, do not rub. Use a spotting brush with a light vertical tapping motion.
- Feather the edges with a damp white cloth to avoid a drying ring.
- Rinse and neutralise between chemistries — never layer an acid on top of an alkali.
- Never put a stained garment in the dryer. Heat sets what you missed and you lose your second chance.
Onboard Notes
- Fresh beats clever. A stain treated within an hour is a stain; a stain treated a week later is an argument with the guest.
- Keep a small spotting kit at the guest laundry point: white pads, spotting brush, cool water spray, neutral detergent, dry-side spotter, tannin formula.
- Bag and tag unknown stains and treat them under good light. Do not improvise at midnight on a silk dress.
- If the fibre is silk, wool or embellished, and the stain is serious, stop and escalate. Doing nothing is recoverable; doing the wrong thing is not.
