How to remove stubborn stains (sweat, food, grass) and when to reach for oxygen bleach vs. gall soap.

Quick choice of the right “stain remover”

Stubborn stains call for two of the most effective yet gentle approaches:

• Oxygen bleach (sodium percarbonate) – ideal for decomposing organic stains, brightening and whitening laundry without chlorine.

• Gall soap – powerful enzymatic cleaning applied locally, directly on stains from sweat, food, grass and grease.

Quick rule: For local fresh stains → gall soap. For set-in and widespread soil on laundry → oxygen-bleach powder (optionally a soak/pre-wash).

How to remove sweat stains

Sweat stains and yellowing in the armpit area result from a mix of sweat, deodorants, and water hardness.
Step-by-step sweat-stain removal:

1. Dampen the area with lukewarm water.

2. Rub in gall soap (let sit for 10–20 minutes).

3. For strong yellowing: a short pre-wash with oxygen bleach (dose per the label).

4. Wash with detergent, ideally fragrance-free, to avoid damaging the fibers.

Recommended products: Gall soap (bar/liquid), Oxygen-bleach powder (sodium percarbonate), Fragrance-free laundry gel for sensitive skin.

How to remove food stains (sauces, fruit, coffee)

Food stains often contain sugars, fats, and dyes.
Step-by-step food-stain removal:

1. Keep the stain wet; do not iron (heat sets it).

2. Pre-treat with gall soap or a stain-remover spray directly on the spot.

3. For colored stains (fruit, wine): soak with oxygen bleach (30–60 minutes).

4. Standard wash — check before drying; repeat if needed.

Recommended products: Gall soap, Stain remover — pre-wash spray, Oxygen-bleach powder (percarbonate).

How to remove grass stains

Grass stains are “green” pigments plus proteins.
Step-by-step grass-stain washing:

1. Moisten and apply gall soap, gently massage the fibers.

2. Let it work for 15–30 minutes.

3. If a shadow remains, a short soak in oxygen bleach.

4. Wash according to the care label; for sports textiles choose a gentle laundry gel.

Recommended products: Gall soap, Oxygen-bleach powder, Gentle laundry gel for sports and functional fabrics.

When oxygen bleach and when gall soap?

• Oxygen bleach (sodium percarbonate):

  • White laundry, greying, lingering odor, organic stains (wine, fruit, sweat).

  • Pre-wash/soak or wash booster.

• Gall soap:

  • Local, fresh, visible stains on cotton, linen, and blends.

  • Ideal for tricky soils like sweat, grass, sauce, oil — precise targeting, without lightening the whole item.

Most common mistakes (and how to avoid them)

• Don’t use hot water on fresh protein stains (sweat, blood) — heat cooks them into the fibers.

• Don’t iron stains — heat sets them.

• Don’t overdo dosing — optimal dosing of oxygen bleach and gel is more effective than “more is more”.

• Check before drying — if the stain remains, repeat the process (drying sets it).
