SIGWolfHoppe's 9 bore cleaning solvent - how long does it last?
I have a large amount of Hoppe's 9 bore cleaning solvent in a glass reagent jar with a glass ground glass stopper.
It's about 3 1/2 years old. I have used it to soak barrels in the past.
Would it still be good? It's not more viscous and seems the same color as before.

StevieI have been using the same bottle for over 8 years, it still works. Just ordered a new one since the old is about out.
I keep trying the new type of cleaners but seem to end up going back to #9, plus its cheaper.

MikeNHHoppes is mostly alcohol and kerosene. Kerosene will separate from water but the alcohol will absorb it. That said, if the jar was sealed, you're probably fine.

I wouldn't say it was exactly sealed. The glass stopper rather seals the bottle, but I don't think it's that tight.

honestlouI've probably used some that was 20-30-40 years old, but I can't be certain.

sigfreundThe batches I use for immersion soaking have been in use for possibly 10 years. I periodically top off the bottles.

captain127I have used bottles made in the 1950's. Pretty much no expiration date

YooperSigsEau De Hoppes.... My favorite scent. I found a small bottle in an old Outers cleaning kit once that looked 1960s.
Worked (and smelled) fine!

BillyBonesNYI still use a large bottle I purchased in the late 70's.
Works like a charm.
