Scout the Fox

Hydrogen peroxide + dish soap + baking soda for armpit stains

Sort of 🧪 Needs real test (provisional verdict)

The hack

Scrub yellow armpit stains with a paste of hydrogen peroxide, dish soap and baking soda, wait 30–60 minutes, then wash.

Where it's popular: Upworthy: viral armpit-stain hack

Scout's verdict

Peroxide is a mild oxygen bleach and dish soap cuts the oily deodorant residue, so the chemistry is plausible. Results vary by fabric and stain age; we haven’t found a controlled test.

Evidence: Family Handyman · The Spruce

Bottom line: Scout tests it on 5 old white tees vs. a store stain remover.

⚠️ Safety

Peroxide can lighten colors: test on a hidden seam. Mix fresh and don’t store it in a closed container. Never combine with bleach or vinegar.
