Safety rules for every treatment
- Test every treatment in an inconspicuous area first — some treatments can fade dyes or damage finishes.
- Blot a wet stain; never rub it. Rubbing pushes the stain deeper into fibers.
- Check the garment's care label and follow it — skip any step the label prohibits.
- Never put the item in the dryer until the stain is completely gone; heat sets most stains.
- Never mix ammonia with chlorine bleach — the fumes are toxic and dangerous.
- Never use chlorine bleach on rust — it can intensify the stain.
- Rubbing alcohol is flammable and can fade some dyes; spot-test first and ventilate the area.
- Acetone dissolves acetate, triacetate, and modacrylic fabrics — check the fabric label first.
- Use cold water first on blood and other protein stains; hot water sets them.
- When in doubt — a valuable, vintage, or delicate item — take it to a professional cleaner instead.
