Yellow sweat stains on your white clothes? No need to throw them away: here’s the solution

• In a heat-safe basin or sink, mix the 30 grams of oxygen bleach and 15 ml of dish soap directly onto the stained areas of the damp garment.

• Gently rub the fabric against itself for 30 seconds so the mixture forms a thick paste over the stain.

Time of action

• Carefully pour the 1 liter of boiling water directly over the treated stains in the basin.

• Let the garment submerge and soak undisturbed for 30 to 45 minutes as the water naturally cools.

Repeat (if necessary)

• For older, severely set-in stains, the operation can be repeated once more if the yellowing has faded but is still slightly visible.

Final wash

• Remove the garment from the soaking water and wash it immediately in your washing machine at the highest temperature indicated on the care label, using your usual heavy-duty laundry detergent.

• Crucial Tip: Check the stain before putting the garment in the dryer. If the stain is gone, dry as normal. If a trace remains, repeat the soak before applying dryer heat, which sets stains permanently.

Why this works:

Unlike traditional chlorine bleach (which actually reacts with body proteins and makes yellow stains worse), the combination of oxygen bleach, degreasing dish soap, and extreme heat breaks down the bonded lipids and proteins from sweat and deodorant, lifting them completely out of the fabric fibers.
