Frequently asked questions

Why vinegar for ketchup?

White vinegar helps dissolve tomato's pigment. Apartment Therapy's testing found a 1:1 vinegar–water mix the most effective home method.

Does hot water help?

No — rinse with cool water first. Heat sets tomato stains.

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.
