Hoppes #9 disclaimer ??

[nekshot]

I plugged a barrel and filled it with #9 to set overnite and to pass some time I read the directions on bottle. It stated do not cork the barrel and I got to wondering why? Can this solvent damage the innards of barrel if left soak, or are they covering liability issues in case a barrel obstruction is left in barrel. I understand the nickle issue but did get to wondering my soaking overnite. What say the experts, shall I fear or fear not?

In time it will damage the barrel.
It will end up looking like a gravel road in the bore.

The old version of Hoppe's number 9 does have a disclaimer on not getting it on Nickle plating. Unfortunately, my father used Hoppes #9 to clean his nickel plated snub nosed S&W M&P 38 pistol a darn long time ago....now the plating is gone from areas of the cylinder. About soaking a bore with it over night, not on my bottle. Kinda common, after cleaning a bore with Hoppes was to run a patch down the cleaned bore with Hoppes on it and put the rifle away. Something I do on occasions with my rifle. But, I shoot them regularly and have a habit of running a clean patch down a rifle bore before going to range. Do you have the pricier Hoppes copper solvent version of #9? Not sure what's on its bottle.

Yea but it smells great. I think someone made a colonge that smells like it......I remember my dad having GI bore cleaner in cans from WWII . My mother almost kicked my dad out of the house...

Hoppe's has ammonia in it. In due time the ammonia will etch steel.

That's probably for the absent-minded tinkerer who is liable to forget that he plugged the bore, and then neglects to remove it before the next time he shoots.

I was shooting with a guy who couldn't get his cartridges to chamber in his Garand. It turns out he had stuck an oily patch in the chamber the last time he cleaned it, for some reason. I'm just glad he put it in the chamber instead of the bore.

I know another guy who did the same thing with his muzzleloader. He had to pull the ball on that one.

I have a bottle of Hoppes that is at least 50 years old. Every once in a while I'll take a smell. that brings back memories

this is the new stuff, copper solvent it says. Well to be on safe side I am only giving it a couple hours to work. I threw a rag of this under the old farm truck seat to help bring a man smell to interior instead of stale old truck smells.

My brother bought Hoppe`s in a steel 1 gallon size barrel when they were changing the formulation. It took the Hoppe`s about 7 years to eat through the welded seam on the gallon steel drum! He poured it into brown glass jugs that I now have since he passed on, not sure if I want to use it or not?Robert

Hoppe's #9 does not have ammonia in it.

Read the MSDS: http://www.copquest.com/knowledgebase/MSDS_Hoppes_No_9_Solvent.pdf

Nor does Hoppe's #9 Plus:

MSDS: http://www.hoppes.com/Hoppes/media/Files/MSDS/Hoppes9/msds-tripac-no9plus-liquid-rev1.pdf

Hoppe's BENCHREST has ammonium hydroxide listed as the #6 component - i.e. not very much.
