Sweat stains on white shirts are frustrating, but they are not permanent. Most stains come from a mix of sweat, deodorant, and body oils that sink into fabric over time. With the right method, even yellow underarm marks can be removed at home using simple ingredients.
If you are searching for How to Get Rid of Sweat Stains From White Shirts, the short answer is this: act early, avoid heat, and treat stains based on their age. Fresh stains need gentle cleaning. Old yellow stains need deeper treatment. This guide shows you exactly how to do both, step by step.
What Causes Sweat Stains on White Shirts?
Sweat alone is clear. The problem starts when sweat mixes with deodorant. Many deodorants contain aluminum salts. When these react with sweat proteins, they create yellow stains.
Other common causes include:
- Body oils that cling to fabric
- Bacteria buildup in underarm areas
- Tight clothing that traps sweat
- Repeated washing without stain treatment
Over time, these factors cause white sweat stains that look dull or yellow. This is why sweat stains on white shirts often get worse after washing.
Things to Know Before Treating Sweat Stains
Before you try to clean anything, pause for a moment. A few wrong steps can set stains forever.
Important rules to follow:
- Never use hot water on stains
- Do not dry the shirt before checking results
- Always read the care label
- Test any solution on a hidden area
If you wear premium clothing like a Threaded Sleeves Sweat Shirt from Zuhoor, gentle care matters even more. Quality fabrics last longer when stains are treated the right way.
