Frequently asked questions

Why do white shirts turn yellow under the arms?

Aluminum in antiperspirant reacts with sweat and builds up over time. A white-vinegar soak dissolves the mineral residue.

How do I prevent the buildup?

Let deodorant dry before dressing, and don't use extra product — buildup is cumulative.

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.
