Just ordered some Videne for sanitising my kegs, i've never used this stuff before and i'm looking for advice on a few things,
as i understand it,when you make the solution, you use 1.25ml to 1 litre of water,
what i'd like to know is, is it advisable to throw away the solution after it's been used once, or can it be used again ? and if so how would you know when to change it ?
i guess it's no great loss if i have to chuck it after one use as it's so cheap, but i'm stingy

i also believe if you stick to the required 1.25ml per litre, it's not necessary to rinse FV, keg etc ? is that so ?
Thanks in advance.
