Chlorine is one of the most damaging elements found in our water supply and anything we can do to reduce its use should be attempted. With this in mind, we offer Sonett Oxygen Bleach. Every bit as effective at whitening and brightening your wash, it doesn't damage the earth. Also fabulous for cleaning hard surfaces such as tubs, sinks or stained mugs. Only 1 teaspoon per wash keeps your clothes looking their best.
