Sodium percarbonate is a very good general purpose cleaner and mild sanitiser. When mixed with warm water it forms hydrogen peroxide, which has an oxygen bleaching effect removing stains and organic matter such as yeast residue and sanitising exposed surfaces.
Over time, sodium percarbonate breaks down into oxygen and water, so there is no need to rinse the product. In order to effectively sanitise, surfaces must be free from all organic material.
Use at a rate of 5g per litre. Ensure coverage over all surfaces that require sanitising. For best results allow wet surfaces to stand for at least 10 minutes.
