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.
