*** We have a couple of these that have arrived with broken tubs. The tubs aren't useable now so you'd need an old tub to store the contents in. ***
The sanitiser is an oxidising agent which upon dissolving in water yields hydrogen peroxide and sodium carbonate (also known as Soda Ash). Sodium Percarbonate acts as a non-chlorine bleaching agent and thus is effective at sanitising surfaces and equipment. The hydrogen peroxide yielded when dissolved in water decomposes over a short time frame (1 hour) into harmless residual products of oxygen and water, hence no additional rinsing is required and is safe for the environment.
Directions: Dissolve in water at the rate of 5g per litre of water and ensure it is in contact with all surfaces of equipment to be used. After use, pour away the solution, there is no need to rinse away. The steriliser should be used within 1 hour of making up to remain effective.
