How old, too old to use? Berryman B-12

[henni]

Found 3 large cans of Berryman B12, one was purchased Jan 2022 but two of them have receipts dated back to 2016.

Can the 2016 cans be used -- caps are fully sealed and all 3 have same weight.

Too old to use ?

Once the can has rusted thru It’s too late

Rust thru in on cap or whole bottle I think rust will outside not inside the can will fine.

Berryman will evaporate.. if its not evaporated and there is liquid in the can... then it's likely fine

I've noticed that old spray cans will sometimes have no propellant, even if they've never been used. As though it slowly leaked away through the valve.

He's talking fuel additive not carb cleaner

Not too old, assuming they haven't been stored out in the rain lol. If the cans are not rusted through and the seals are all intact, you will be fine. 7 years may seem like a long time but those cans are stout enough.
