Nothing is more frustrating than pulling a white shirt, towel, or bed sheet out of the laundry only to find it has developed an unpleasant yellow tint. Over time, what was once bright and fresh can start looking dull, dingy, and - let's be honest - just plain old.
So why does this happen, and more importantly, how can you get your whites looking fresh again? Let's break it down.
Why Do Whites Turn Yellow?
There are a few key culprits behind yellowing whites, and understanding them can help you prevent future laundry disasters.
1. Body Oils & Sweat
The most common reason whites turn yellow is a buildup of body oils and sweat. Over time, these natural oils soak into fabrics, causing discolouration - especially in areas like armpits, collars, bedsheets and pillowcases.
2. Too Much (or Too Little) Detergent
Using too much detergent can leave behind a soapy residue that traps dirt and oils in your fabric. On the other hand, using too little detergent means your clothes aren't getting fully cleaned, leaving behind grime that builds up over time.
3. Hard Water Minerals
If you live in an area with hard water, the minerals (like calcium and magnesium) can settle into fabric fibers, making whites look dull and yellowed.
4. Improper Storage
Storing clothes in plastic bins or non-breathable spaces can cause whites to yellow due to a lack of airflow. Additionally, whites that sit unused for long periods can develop a yellow tinge simply from oxidation.
5. Chlorine Bleach Overuse
Ironically, using too much bleach can actually cause yellowing. Chlorine bleach can break down fabric fibers over time, causing them to lose their bright white appearance.
How to Fix Yellowed Whites
Now that we know the reasons behind yellowing, let's talk solutions!
1. Deep Clean with Nellie's Oxygen Brightener
For stubborn yellowing, give your whites a deep clean with Nellie's Oxygen Brightener - a powerful, chlorine-free formula that lifts stains and revives dingy fabrics.
How to Use It:
- Add 2-3 scoops to your washing machine along with Nellie's Laundry Soda and run a normal cycle with hot water.
- For extra-tough stains, create a paste with Oxygen Brightener and water, apply it to fabric, let it sit for 30 minutes, then wash as usual.
2. Wash in Hot Water
Hot water is better at breaking down oils and grime. Be sure to check fabric care labels first - some materials like wool and silk should only be washed in cold water.
3. Avoid Fabric Softeners & Bleach
Fabric softeners can leave behind residue that attracts dirt, and chlorine bleach can weaken fibers, making yellowing worse over time. Instead, stick with Oxygen Brightener for a gentler, more effective clean.
4. Dry Whites in the Sun
Sunlight is a natural bleaching agent! Instead of using the dryer, hang your whites outside to dry. The UV rays will help brighten fabric without harsh chemicals.
5. Use Filtered or Softened Water
If hard water is the culprit, consider using a water softener or adding a laundry booster to help prevent mineral buildup.
6. Pre-Treat Armpit Stains with an Oxygen Brightener Paste
Yellowing around the underarms is usually caused by a buildup of sweat and deodorant.
How to Fix it:
- Mix Nellie's Oxygen Brightener with water to form a paste.
- Apply directly to the stain and let sit for at least 30 minutes before washing as usual.
7. Laundry Strip Every Few Months
Over time, detergent, body oils, and fabric softener residue can build up in your clothes, making whites look dingy.
How to Laundry Strip:
- Fill a tub with hot water.
- Add 2-4 scoops of Oxygen Brightener and let your whites soak for a few hours, stirring occasionally.
- Drain and wash as usual for bright, fresh results!
Keep Your Whites Bright for the Long Haul
Once you've restored your whites, you'll want to keep them that way! Here are some quick tips to prevent future yellowing:
- Wash whites separately from colours.
- Use Oxygen Brightener in every load for ongoing freshness.
- Store whites in a cool, breathable space.
- Skip the bleach - stick to gentler, more effective alternatives.
With the right care and a little help from Nellie's Laundry Soda and Oxygen Brightener, you can keep your whites looking crisp, clean, and as good as new!
