Hi everyone, made a 1% solution of Potassium Bromide a couple of years ago for Pyrocat HD and wondered if I could use what is left in the bottle to make some more Pyrocat HD - or should I start with fresh again

Thanks, Paul

Forever.
It is a simple salt and can not breakdown or decompose.
If you have it in a plastic bottle the bottle will go bad before the KBr does.
Your bottle may also not be totally sealed and have evaporation of a little water and so it maybe more then 1% now.
