The worst smelling gun cleaner?

Yes it has ammonia in it (or so it smells) although it doesn't hold a candle to the Military rifle bore solvent that comes in the tan, rectangular can- that stuff is raunchy.

Gunzilla makes me nauseous.

Sweet's 7.62.

Yeah, Sweet's is nasty stuff. I try not to use it at all.

I agree with Sweets, but it does cut copper fouling.

It works. Just like the goggles work to keep it from burning your eyes.

Sweets will absolutely knock you over if you get a good whiff of it. But to answer the OP's question, they put ammonia in there because it's a copper solvent.

Montana Extreme copper solvent ".50 bmg formula"

The smell of Hoppes makes me gag.

Huh. I know plenty of folks who have to be restrained from dabbing a bit of Hoppe's behind the ears before a hot date!

Worst smelling gun cleaner, easy, any of us who just came home after 10 days in the hunting cabin with 10 people.

Heretic! Burn him!

Hoppes #9 is STRONG. Even using it in the garage, I have to be quick about replacing the lid, keep a fan running, and throw the used patches in a trash bag immediately instead of leaving them on the work table.

But to me, the worst smelling cleaner is CLP. I don't know what it is, but there is something in it that just smells bad to me.

Hoppes is pretty tame compared to the WWII milsurp bore cleaner we used when I was a kid.

Yes, burn the heretic! Hoppes is the smell of guns.

Butch's Bore Shine is pretty funky, but it's just that ammonia.

Blasphemy...Shortly after we were married, the ex asked if there was any particular perfume I preferred for those "personal" times. I said "yeah, the one with the number in the name". She asked "Chanel #5"? I replied "No....Hoppes #9".
But to answer the original question....Sweets 7.62 without doubt.

Break Free Powder blast is some pretty strong stuff also.

Why does Birchwood Casey 2 in 1 Bore Scrubber stink so bad?

Ohh yea my wife gripes about the smell evey time I clean a gun.

Hoppe's Copper Solvent stinx way worse than good ole #9. And Shooter's Choice is my pick for the worst....ulp CLP and especially RIG 2 and Hoppe's Elite are among the best for cleaning inside the house. IMO, of course.

Dang, beat me to it. Hoppe's copper solvent is rank. Outer's oil smells like rancid butter (to me.)

Hoppes smells like victory!
Sweet's is just outrageous
