Bleach got into the wash by accident

Short answer: Chlorine removes color permanently, and the fiber weakens at the same time exactly where it hit. Rinse immediately with cold water, and accept that the color will not come back on its own, whatever you try afterward.

What chlorine does to the fabric

Chlorine bleach breaks down the dye's molecules, and that cannot be undone afterward. At the same time, chlorine attacks the cellulose fiber in bamboo viscose itself and weakens the fabric exactly where it hit, so a hole can appear later.

The first step right away

Rinse the area thoroughly under cold running water immediately, so the effect stops as fast as possible. Use plenty of water and rinse for a while. Then wash the item alone with no detergent. The longer the chlorine is allowed to sit, the larger the pale spot becomes.

What you can do afterward

On a solid dark item, a fabric dye can give an even color again, but the result rarely turns out completely identical to the original. On white, the spot does nothing, and the item can keep being worn just as before.

Underwear is hit hardest

See bamboo underwear for women, where a small spot is far more visible than on a plain t-shirt, since the fabric sits close against the skin. Chlorine damage here usually means the item is thrown out entirely.

How to avoid it going forward

Store chlorine and stain removers well away from the machine and laundry area, ideally in a completely different cupboard. Use oxygen bleach for whites, since it works on dirt without attacking color and fiber the same drastic way chlorine does.

See the rest of the range

See bamboo t-shirts for men and bamboo clothing for women, where you can find new favorites if the damage to an item unfortunately cannot be fixed.

Why oxygen bleach is the safe choice

Oxygen bleach works more slowly than chlorine and mainly attacks organic stains like fruit, grass and blood. That makes it suitable for whites, without carrying the risk of damage to colored fabric along with it.

Check the label before washing

Many bathroom and kitchen cleaners contain chlorine, even when it does not always clearly say so on the label. Read the ingredient list carefully before using a product anywhere near the laundry basket or hamper.

What about the smell of chlorine

The smell usually disappears after a couple of washes with no detergent, ideally with good airing in between. If it lingers in the fabric, the fiber is probably damaged enough that the item should be discarded anyway.
