How to Whiten Bras that Turn Gray in 4 Effective Methods
Are you glaring at your dull, grayed bras that were once sparkling white and wondering why they lost their pristine condition and whether you can turn them around?
Well, sweat and improper bra washing are the main contributors to discoloration in white bras. Also, the accumulation of body oils, dead skin cells, and detergents can cause fabrics to lose their luster resulting in the dreaded gray hue.
Do not despair! Revert your bra to its former glory following simple and effective solutions. From soaking solutions to gentle yet powerful stain removers, this article explores how to whiten bras that turn gray using easy steps.
Why Do White Bras, Turn Gray?

There are two main reasons why white bras turn gray:
1. Due to Sweat
Despite being colorless, sweat can discolor your white bra. But how does this happen?
Well, it occurs when the sweat mixes with other elements. For instance, deodorant contains aluminum that combines with sweat discoloring your bra. Also, it mixes with the bacteria in your skin, forming a yellow color that discolors your bra.
Use cold water to wash your bra once you notice the stain to help remove it. Shun away from using hot water as it locks in stains rather than removing them.
2. Due to improper bra washing
Nylon, a common bra material, absorbs dye particles during washing. When you clean your bras all together without sorting them by color, you risk staining your white bras. Stained nylon bras are hard to whiten.
How to Whiten Bras that Turn Gray?
Did you know that there are a number of proven techniques that whiten your grey-stained bra? Let us explore these methods.

1. Cold Water Method
The cold water method is the most common method of whitening your bras. Let’s get into its details.
First, ensure that the water is cold since warm or hot water damages the delicate bra fabric and causes bras to shrink.
The next step is to presoak the bras using mild soap. If you are dealing with stubborn stains, pre-treat the bra before washing. Put detergent on the stained spots and rub in slowly before allowing it to penetrate and loosen the stain for about 15 minutes.
Wash the bra gently using mild soaps or detergents. Avoid harsh soaps, detergents, solvents, or chemicals since they damage the delicate bra fibers. If necessary, add a spoonful of baking soda to the cold water to help whiten the bras and remove odor, color, and stubborn stains.
Gently rinse the bras several times till the water becomes clear.
The last step is to air-dry the bra, preferably under direct sunlight. The sun contains bleaching capabilities that further brighten your bra.
2. Lemon Juice Method
Lemon contains citric acid, known for its ability to break down stains. It is gentle on bra fabric and will help whiten your bras. The lemon juice method entails soaking your bra in a lemon juice solution.
Pour enough cold water into a basin or sink and add some drops of lemon juice. Mix the solution and put your bras to soak in for a few minutes (approximately 30 minutes). Once the time lapses, rinse the bras. The next step is to wash the bras gently using mild soap, rinse them several times and allow them to dry under direct sunlight.
Some people also prefer mixing lemon juice with baking soda for best results. Sprinkle a spoonful of baking soda in the stained area and add the lemon juice allowing it to sit for about half an hour. Rinse the bra and wash it normally.
Before drying, pour lemon juice on the stained area and dry it in direct sunlight. The combination of lemon juice’s natural bleaching properties and the sun’s ultraviolet rays help brighten the fabric.

3. Vinegar Method
Vinegar acid tears apart stains restoring the brightness of your bras, without damaging delicate fabrics. It is an effective method of removing stubborn stains.
Here is how to whiten the bras using vinegar:
Prepare the vinegar solution
Fill in your washing basin with water and add a cupful of distilled white vinegar for each gallon of water used. You can adjust the vinegar-to-cold water ratio depending on how many bras you are whitening.
Soak the bras
Submerge the gray bras in the vinegar solution and ensure they are fully covered. Allow them to soak for 30 minutes to one hour to help loosen dirt, residue, and trapped oils contributing to the grayness.
Agitate and scrub gently
The next step is to agitate the bras in the vinegar solution by swirling them around gently. If there are specific spots with stubborn stains or discoloration, lightly scrub using a soft brush or toothbrush. Be careful not to scrub vigorously to avoid damaging the fabric.

Rinse thoroughly
It is time to rinse your bras using cool running water. Rinse till the water runs clear and no vinegar smell remains.
Wash with mild detergent
This step helps remove any residue leaving the bra fresh and clean. Wash the bras by hand or using a washing machine, with a mild detergent specially formulated for delicate fabrics.
Air dry
Gently squeeze dry the bras and do not wring to prevent fabric damage and bra stretching.
Hang the bras to air dry in an airy environment where there is no direct sunlight. Do not use a dryer to prevent the bra from shrinking and causing fabric damage.

4. Soak method
Soaking your bras allows the detergent to saturate the bra fabric, loosening and removing stubborn stains.
Here is how:
Add a suitable whitening agent (oxygenated bleach, laundry whitening product, or hydrogen peroxide) to cool water in a washing basin or sink. Read and follow the washing instructions of your preferred detergent.
Place the gray bras in the solution and ensure they are fully submerged. Allow them to soak for one (1) to two (2) hours to help lift stains and brighten the fabric.
While soaking, gently agitate the bras in the solution by swirling them around or lightly squeezing them. It helps the whitening agent penetrate the fabric and work more effectively.
After the soaking time lapses, remove the bras and rinse them thoroughly using cold water to remove any residual whitening agent.

Wash the bras with a mild detergent specifically designed for delicate fabrics. Hand-wash or machine-wash using a gentle cycle.
Identify an adequately ventilated space suitable for air drying your bras. Dryers are not recommended as they damage the bra’s fabric.
Once the bras dry, check if the grayness has significantly diminished. If necessary, repeat the soak method or target specific areas containing the stubborn stains by applying a diluted whitening agent and gently scrubbing before washing again.
Additional Questions
Why do my bras turn gray?
Your bras can turn gray due to a multitude of factors. One of the culprits could be sweat and lotions which might cause the material to yellow over time. However, a common cause is washing white bras with colored clothing. If any dye bleeds from the colored clothing, your white bras could absorb it and turn a dull white or gray. Over my many years of experience, I’ve seen this happen quite often and it’s a common issue faced by many.
How can I keep my white bras white?
Keeping a white bra white may seem like a daunting task, but with the correct care, it is achievable. Always opt for hand-washing your bras using a gentle detergent and cool water. **Avoid bleach and fabric softeners** as they can actually damage the fabric and cause discoloration over time. During the washing process, rub the fabric together carefully to remove dirt or stains, but ensure not to distort the shape of the bra. As someone who prides themselves on maintaining their whites, I can definitively say that this method helps to prolong the pristine appearance of your white bras.
How long to bleach a bra?
While I generally advocate for avoiding bleach when it comes to bra care – since it can harm the delicate fibers and contribute to discoloration – if you still want to proceed, be sure to use it sparingly and monitor the process closely.
How do I keep my bras looking new?
To keep your bras appearing brand-new, follow the same guidelines outlined above for white bras: hand wash them in a gentle detergent and cool water, avoid using bleach, and refrain from using fabric softeners. Also, take care during the washing process to not stretch or warp the bra’s shape. Keeping your bras looking new is all about harnessing the right preservation tactics, and in my years of experience, I’ve found that these steps ensure the longevity and maintain the appearance of bras.
