How to Whiten Yellowed White Clothes

Why White Clothes Turn Yellow

White clothes yellow over time for several reasons: sweat and antiperspirant buildup, body oils, hard water mineral deposits, improper storage, and even the optical brighteners in detergent breaking down over time. The good news: yellowed white clothes can almost always be restored to bright white with the right combination of oxygen bleach, acid, and enzyme cleaners.

What You'll Need

• OxiClean White Revive Power Paks
• Heinz White Vinegar
• Hydrogen Peroxide (12%)
• Shout Active Enzyme Laundry Stain Remover Spray
• Baking soda
• Cold or warm water

Method 1: OxiClean White Revive Soak (Best Overall)

This is the most effective and easiest method for overall yellowing of white clothes.

1. Fill a basin or sink with warm water.
2. Dissolve 1–2 OxiClean White Revive Power Paks in the water. The oxygen-releasing formula penetrates fabric fibers and breaks down yellowing compounds at a molecular level.
3. Submerge the yellowed white clothes completely. Make sure all fabric is fully saturated.
4. Soak for 6 hours — or overnight for severely yellowed items. The longer the soak, the more effective.
5. Machine wash cold with another OxiClean White Revive Power Pak. Check before drying.

Method 2: White Vinegar + Baking Soda (For Sweat-Related Yellowing)

Best for yellowing caused by sweat and antiperspirant buildup.

1. Soak in white vinegar. Fill a basin with equal parts Heinz White Vinegar and cold water. Soak for 1 hour to dissolve aluminum and mineral deposits.
2. Apply baking soda paste to any heavily yellowed areas. Scrub gently with a soft brush.
3. Spray with Shout Enzyme Spray on underarm and collar areas. Let sit 15 minutes.
4. Machine wash cold with an OxiClean White Revive Power Pak.

Method 3: Hydrogen Peroxide Soak (For Bright White Restoration)

Best for restoring brightness to overall dull or yellowed white fabric.

1. Mix 1 part hydrogen peroxide with 3 parts cold water in a basin.
2. Submerge the white clothes and soak for 30–60 minutes.
3. For extra power: Place the basin in direct sunlight while soaking. UV light activates the hydrogen peroxide for enhanced whitening.
4. Machine wash cold with an OxiClean White Revive Power Pak.

The Ultimate Whitening Combo

For severely yellowed white clothes, combine all three methods:

1. Soak in white vinegar solution for 1 hour
2. Apply baking soda paste and Shout Enzyme Spray to stained areas
3. Soak in OxiClean White Revive solution overnight
4. Machine wash cold with OxiClean + a splash of hydrogen peroxide in the drum
5. Air dry in sunlight for extra UV whitening

What NOT to Do

• ❌ Don't use chlorine bleach — it can react with sweat proteins and worsen yellowing, and weakens fabric fibers over time
• ❌ Don't use hot water — heat sets yellowing permanently
• ❌ Don't put in the dryer until fully white — heat locks in any remaining discoloration

Frequently Asked Questions

Can severely yellowed white clothes be restored?

Yes — in most cases. The ultimate combo of white vinegar soak, OxiClean White Revive overnight soak, and hydrogen peroxide can restore even heavily yellowed white clothes. The exception is fabric that has been heat-set repeatedly in the dryer while yellowed — this can be very difficult to reverse.

Does sunlight whiten clothes?

Yes — UV light has a natural bleaching effect on white fabric and activates hydrogen peroxide for enhanced whitening. Air drying white clothes in direct sunlight is a free and effective way to maintain brightness over time.

How do I keep white clothes white after washing?

Add an OxiClean White Revive Power Pak to every wash of white clothes, add half a cup of white vinegar to the rinse cycle, and air dry in sunlight when possible. Pre-treat underarms and collars with Shout Enzyme Spray before every wash to prevent buildup.
