How to remove sweat & deodorant (yellow armpit) stains
Yellowing is sweat proteins reacting with deodorant aluminum — and chlorine bleach makes it WORSE.
- Difficulty:
- moderate
- Water:
- Warm, as the label allows.
Step by step
- Pretreat: soak in a solution of white vinegar and warm water, or brush on a baking-soda paste (or oxygen bleach), and let sit 30–60 minutes.
- Work in an enzyme detergent.
- Launder in the warmest water the label allows; air-dry and check.
Do
- ✓ Use oxygen bleach, vinegar, or baking soda
- ✓ Reach for enzymes
Don’t
- ✗ Never use chlorine bleach — it deepens the yellowing
- ✗ Don't dry until gone
Before you start
- • Act fast. Fresh stains lift far more easily than ones that have set.
- • Blot, don't rub — rubbing drives the stain deeper and frays the fibers. Work from the back of the fabric to push it out the way it came in.
- • Check the care label first. Never exceed the garment's maximum temperature; if it says wash cold or dry-clean only, follow it.
- • Test any treatment (oxygen bleach, hydrogen peroxide, rubbing alcohol, vinegar) on a hidden seam first — some can strip color.
- • Never tumble-dry until the stain is completely gone. Dryer heat sets most stains permanently — air-dry and check, then re-treat if needed.
