How to keep your whites bright

Raise your hand if white clothes are your go-to in the summer! 🙋🏾‍♀️🙋🏿‍♂️🙋🏻‍♀️ You can take your white pieces to the next level with Supersalt, our oxygen booster. Supersalt is not bleach—it's color-safe and can be used to brighten greying or yellowing whites (among other things!)


With every wash, add one tablespoon of Supersalt into the drum along with your detergent, then wash your white load normally.

Overall brightening:

Dull whites can benefit from more TLC. Do a pre-soak with Supersalt the night before washing: dissolve 1/2 Tbsp in a bucket of warm water, submerge the dull whites overnight and wash normally the next day.

Stain treating:

If there's a stain you're targeting (rather than a need for overall brightening), use Supersalt to pre-treat the stain.

Wet the stained area with water, cover it with a light layer of Supersalt, and let it sit for 15 minutes. It will become a paste, which you can work into the stain using a laundry brush or old toothbrush. Afterwards, wash normally.
