How to Remove Sweat / Yellow Armpit Stains from Colored Shirts
Removal Method
1
Mix 1 part white vinegar + 1 part water. Soak the armpit area for 30 minutes.
2
Make a paste of baking soda and water. Apply to the stain and work in gently.
3
Wash in cold water (hot water sets protein stains). Check before drying.
💡 Alternative Method
Enzyme-based pre-soak (like BioKleen) for 1 hour before washing.
🚫 What NOT to Do
- Do not use hydrogen peroxide on colored shirts (bleaching risk)
- Do not use bleach (makes yellow stains worse)
🔄 If Nothing Works
Enzyme-based pre-soak overnight.
