Now that I don’t know.

Not a clue.

I’d wager it’s not 91% anymore?

Maybe something online about that.

I know peroxide is dodgy after a while.

From what I can find....it may have degraded a TINY bit.

So, I know it’s (likely) at least 71% :-)

That’s my science, and I’m sticking with it!

“I know peroxide is dodgy after a while.”

H2O2 naturally decays. It has a half life like radioactives do (it’s not radioactive, LOL, I didn’t say that). Just over time an oxygen atom breaks loose and you get oxygen and water.

Isopropyl mixed with water remains isopropyl mixed with water.
