Should I toss my Rodinal

[Xmas]

> split each new bottle of Rodinal up when I get it.

This i fine idea which I practice. The amount of air which the last drop has "seen" is remarkably less. I open 10 100 ml bottle 10 times before it is finished, but 500 ml bottle 50 times. Beside this I discard the last few milliliters.

Un-necessary with Rodinal or a clone even if you need more than 100 years life.

It is also useful as drain cleaner or damaging skin or eyes.

I use it to last drip from every bottle not had a problem yet.

Kept one bottle 1/4 full for 25 years used to last drip.

I thought Rodinal proved to get 125years old.
Maybe I'm mixing things up...
