I have a couple of bottles of Hoppes no 9 that I bought 20 years ago give or take. Does anyone know how the tell if it is the old formula? They are in big glass jars. I don't even know how it comes nowadays.

Drink one, and if you die of cancer when you are 95?
It was the old formula.

But seriously, Who cares.
It's Hoppes #9.

It's all good.

Use it.

I was just curious. Got enough to last until after I die, even if I don't drink it:)

Nitro powder solvent formulas, including Hoppes #9, have changed over the years as smokeless gunpowders and priming compounds have changed. I did read that Hoppes removed a carcinogen from the formula a few years back but I did not make a note of the date. I always made a point of not eating, drinking or smoking while cleaning guns and thoroughly washing hands afterwards so I was not concerned. I have discovered this: guncleaning patches with #9 dropped in the kitchen wastecan repel gnats.

FWIW ... about 10 years ago I had just about finished-off my, at that time, ~10 years-old 16oz bottle of #9 so I bought an on-sale 32oz replacement. I remember noticing a color & aroma difference in the two. It may have been a batch-difference and/or age ... or even the result of one of the formula changes we have all read about.

Bottom line: I do not know ... but ...

What I do know is that the new stuff still does the job and smells great!

If they ever remove the amyl acetate from the formula their #9 business will dry up. :)

And, finally, in answer to your question ;), contact the MFR about this. They should be able to help you with that ... unless their lawyers have instructed them not to.

that was removed from the original #9 formula is nitrobenzene - 'a known carcinogen'.
But, when you take a sniff of the old #9, as compared to the new, your sense of smell says "Yes! That's the real stuff!" (assuming you grew up with the original formula).
FWIW, Bruno's Shooter's Supply was selling the old formula #9 as recently as a few years ago - I bought a gallon. I don't know whether they were obtaining the Hoppe's directly in the old formula, or simply adding the nitrobenzene.
Gun cleaning, as such, lost its charm for me a few decades ago, but having the old #9 makes it less of a chore.

My understanding, from the smith I use, Hoppe's was urged by the EPA to remove 2 chemicals they used in the Hoppe's formula, chemicals no longer allowed ! The smell is the same, but doesn't clean as it used to. Can be used as a room deodorizer though.

I can use it to clear my wife out of whatever room I'm in. :)

:confused: One of the rare folks who does not like the aroma, huh?

No. 9 predates Channel No. 5
by about 15 years.
