“This is my first time buying the steriliser And I’ve now used it once. The recommended concentration seems quite effective going by the typical odour and irritation that is typically produced from this compound. I’m confident that it will affectively sterilise my beer bottles and brewing vat. It will be the first time I have only let it work for the recommended 10 minutes, the other brand of used recommend one hour. I look forward to seeing the results.and if Positive will make the sterilisation process so much faster.”
