I am not talking about part used dilutions here, I always use once and throw away, it is just the part empty bottles of concentrate. What are the views on this?
I think a better way of keeping chemicals long term is with a little chemistry. If you buy the chemicals that absorb oxygen as liquids in powder form, it's easier to keep them, then cook up small batches of chemistry, rather then concentrates.
