Hell all. I am conflicted here. With the PBW and Sodium Percarbonate (SP), as they do the job by oxidizing. Does this mean that the kegs should be fill to the top to be effective. I would have thought so which means an awful lot of product will be required to clean say a 50 litre keg but if it is needed, then so be it. If anyone is interested, the link below is to a good site on SP but it does not answer this question. TIA
Sodium percarbonate is the active ingredient so it is a very powerful cleaner. Sodium percarbonate uses active oxygen to penetrate carbon or protein soils and has a high kill rate on wide range of microorganisms making it an effective sanitiser as well as cleaner.
