100% pure sodium percarbonate
1 kg bleaching salt can be used for pre-wash soaking and for bleaching white and non-fading coloured clothing. It is made of sodium percarbonate which dissolves into bleaching and antiseptic oxygen and soda during the washing procedure.
To remove stains, either soak laundry in bleaching salt (be careful with dosage) or moisten the spot, apply salt evenly and let soak. Bleaching salt can also be added to the laundry in the machine by pouring it directly onto the clothes (dosage approx. 2 - 3 table spoons).
In order to remove very persistent spots, run washing machine for a short while, shut off, soak as required and then continue the cycle.
Bleaching salt as scouring agent
Cleans as a scouring agent even heavy duty spots such as burnt milk on ceramic tops. Apply with wet sponge. Let soak and rub off.
