How to Get a Yellow Stain Out of a White Shirt

Yellow stains on white shirts are a real pain. Whether it’s sweat, body oils or bad washing, they can turn your crisp white shirts into dull stained fabric. Learning how to get a yellow stain out of a white shirt can save your favourite shirts from the bin. Below we’ll cover the main reasons for yellow stains and simple ways to remove them with household items.

Reasons for Yellow Stains on White Shirts

Before we get into the removal methods, we need to understand why these yellow stains appear. Knowing the reason will help you choose the best method for stain removal.

• Sweat and Deodorant Reaction: The most common reason for yellow stains is the reaction between sweat and the aluminium salts in many deodorants. Sweat alone is not yellow, but when mixed with deodorants it forms a yellow residue that sticks to fabric.
• Oxidation: Over time, exposure to air can cause white fabric to yellow, especially if not stored properly or if there’s detergent residue on them .
• Bad Washing: Detergent or fabric softener build up, especially if used too much, can cause white shirts to yellow .
• Too Much Bleach: While bleach is used to whiten clothes, using too much or using it incorrectly can weaken fabric fibres and cause yellowing .

Tools and Ingredients You’ll Need

You don’t need special products to get your white shirt looking like new again. Many household items can remove yellow stains. Here’s what you’ll need:

• Baking Soda: A gentle abrasive that lifts stains without damaging fabric.
• Hydrogen Peroxide: A mild bleach that whitens and removes tough stains.
• White Vinegar: A natural deodoriser and stain remover.
• Dish Soap: Especially good for oil based stains.
• Lemon Juice: Acts as a natural bleach and brightener when exposed to sunlight.
• Toothbrush: For scrubbing without damaging delicate fabric .

How to Remove Yellow Stains Step by Step

Now let’s get into the simple ways to get a yellow stain out of a white shirt. These methods use common household items.

Method 1: Baking Soda and Hydrogen Peroxide Paste

This method combines the whitening power of hydrogen peroxide with the abrasive properties of baking soda to lift and remove yellow stains.

Steps:

1. In a small bowl, mix equal parts baking soda and hydrogen peroxide to form a thick paste.
2. Apply the paste directly to the yellow stain using an old toothbrush.
3. Scrub the area in a circular motion, making sure the paste gets into the fabric fibres.
4. Leave the paste on the stain for 15-30 minutes to break down the stain.
5. Rinse the shirt with cold water and check the stain.
6. If needed, repeat the process until the stain is gone .

Method 2: Lemon Juice and Salt Scrub

Lemon juice has natural bleaching properties and when combined with salt it’s a great stain remover for white shirts.

3. Gently scrub the stain with a soft-bristled toothbrush, making sure to work the solution into the fabric.
4. Leave the shirt in direct sunlight for 2-3 hours. The UV rays from the sun will help the lemon juice do its magic.
5. Once the shirt is dry, rinse with cold water to remove the salt and lemon residue.

Method 3: White Vinegar Soak

Vinegar is a great household cleaner and can remove yellow stains while also neutralise odours in fabric.

6. How to Prevent Yellow Stains on White Shirts

Now that you know how to get a yellow stain out of a white shirt, let’s talk about preventing them in the first place. Prevention is always better than treating stains after the fact and with a few simple steps you can keep your whites looking fresh and clean.

Switch to Aluminium-Free Deodorants

One of the main causes of yellow stains is the reaction between sweat and the aluminium compounds in antiperspirants. Switch to an aluminium-free deodorant and you’ll reduce the risk of underarm stains on your white shirts .

Wash Whites in Cold Water

Hot water can set stains into the fabric making them harder to remove later. Washing your white shirts in cold water helps preserve the fabric and prevents yellow stains from becoming permanent. Cold water is especially effective when used with stain-fighting products like vinegar or baking soda .

Store your white shirts in a cool, dry place to prevent yellowing caused by oxidation. Don’t overexpose your whites to direct sunlight or fluorescent lighting when storing them, it can cause discoloration .

Don’t Use Too Much Detergent or Fabric Softener

Too much detergent and fabric softener can leave residues that over time can cause yellowing on white shirts. Always follow the instructions on the packaging and rinse thoroughly to avoid buildup.
