Supersalt is now back in stock! Thanks for your patience as we worked through packaging supply chain disruptions. It's the same great product, but with new reusable packaging. Plus, there's over 33% more product (with no price change)!

Use Supersalt to boost the brightness of greying and yellowing whites or blast stains from fruit, red wine, tea, coffee, grass and blood on most fabrics. Ensure compatibility by testing a small patch. Do not use on wool or silk.

Sodium percarbonate and washing soda (no chlorine bleach!)

Net wt. 32 oz (907g)

Add 1 tbsp directly to the drum of a high-efficiency washer with Corewash, select any water temperature (warmer yields better results)

For pre-soaking:
Dissolve 1/2 tbsp in a bucket of warm water, submerge dull whites overnight and wash

For stain treating:
Wet the stained area, cover with a light layer, let sit for 15 minutes and wash
