Just bought a pot of sodium percarbonate, (bruclens steriliser for beer & wine), but instructions are a bit weird. Says on it 4 teaspoons per 5 litres but... surely I dont need to completely fill my container though right? Which is what it looks like it is saying. So for a 19lt container, how much should I use? would 1 teaspoon in a litre of water then shake it around ok? Also as I know i have to rinse it well, is tap water ok for this?
To be completely honest Im a bit disappointed, I got it online and it said its specifically for beer and wine but am sure there are better suited chemicals for this job.
