Have a gallon can that has been in an unheated garage (FargoND) for about 10 years.

Dunno about it going bad; I can say though that it's not good to sit it on a concrete floor that long as the can will rust out from the bottom due to condensation. Happened at a shop I was at years ago and that's not a fun mess to clean up.

It does seem long ago (more than 10 years) they reformulated and it became much weaker, presumably more EPA-friendly. This is the green can of acid with the basket that I'm referring to.

I've had one of those rust out also.

Seems to me that the carb cleaner or some of the junk it removed must have been attracting water from the air, and that would mean it is going bad.

Pretty sure in the case I mentioned it rusted out due to sweat from the concrete floor it was sitting on. On the shelf it wouldn't have happened.

I have 2 of the gallon cans.One is the old stuff and one is the new stuff.Both are Berryman's Chem Dip.
The old one rusted out on a wooden shelf!(the smell never goes away!)
So,I poured the remains in an old anti-freeze plastic jug and set in a stainless pan.
Never seen it go bad,but I don't know how old mine is.

Well, I tried it. Opened can. No film or scum on top.
My '98 car had a hesitation. So I soaked the EGR valve for about 4 hours. (seemed to cure the problem 4 years ago) No more hesitation, but don't know for sure if that was the problem. Never got any codes.
The cleaner did not remove all the carbon that I expected it to dissolve. So maybe it lost its potency. Gave EGR some PB Blaster too.
If I have same problem, I'll soak it 24hr. Drive my old '57 beater for a day! Not paying $100 for that valve. Maybe visit a junkyard....
