Sodium Percarbonate is a wonderful asset to have in the laundry. It not only brightens colours, but gets out those stubborn stains on clothing. All one has to do is dissolve a tablespoon of SP in 5 litres of hot water, place items in the mix (ensure that they are covered, then leave it to soak overnight. Then wash as usual the next day. Stains gone and colours brighter.
The added bonus is that if you are not on town water, Sodium Percarbonate is safe to use in a septic system. Very simple, no stress.
I have been using Percarbonate for some time now and love that I can purchase it easily from Under Your Sink. It removes stains safely and without any harmful chemicals. It can be used pre-wash as a soaker or can be added to the wash in the machine.
