How long does a wax last in its container?

I was going through my detailing supplies and came across a container of Poorboys Natty's Paste Wax a bought about 3 years ago and never used. Is it still ok to use? I wasn't sure if waxes had a shelf life.

I hope not. I bought some PB Natty's Red paste wax this year that even if I wax both cars once a month, it'll take me three years to use it all. I'll be interested to hear what people have to say.

I would think that as long as the wax or any product has not been kept in extreme conditions such as heat and cold they should last for a number of years. I would use the PB red without worries if it has been stored properly.

Ive got some paste waxes that are more than 3 years old, just keep it sealed and out of high temp swings.

I have some plain old Carnauba wax that is 40 years old and it is still perfectly fine. And it has been on a shelf in my garage, which gets up to 140 degrees in the summer.
It is Harly Wax. I also have a couple of bottles of Meguiar's Cleaner wax liquid that is OK too. It was purchased at PepBoys in 1977 and it was $2.29 back then.

I have some paste waxes I bought 22 years ago and they are still ok. I have some liquid waxes I stored in the hot garage that dried out, though. Drying out seems the only problem.

Does anyone know if it would last longer or be better in a refrigerator then in the heat and cold of a garage?

I've heard paste waxes last longer in a frig, but liquids don't. Idk if this is true or not.

My favorite wax from years ago was Classic Slipstream, a hard paste wax which was discontinued in the late 70's. Kinda similar to today's Collinite's hard paste, but it had pretty fair cleaning properties. When I heard the news of its demise in 1980, I went around and bought up all the cans I could find. I'm now down to my last tin, so it's been 30 years. I never allowed it to freeze and never had an issue. My bigger problem was rust on the inside of the lid.

I keep my waxes in zip-lock bags to seal out the air. Air and temp swings are a waxes worst enemy.
