OK To Leave Hoppes in the Barrel?

if it causes any harm, i'm in trouble cause i've been storing rifles with hoppe's in the bore for years.
seriously, i haven't noticed any kind of damage, and the hoppe's does work on the bores while they're sitting there.

y'all have a good day, Keith

Leaving #9 in the barrel will not damage the steel, but there are much better long term storage options that do a better job of rust prevention than #9. I'll treat a rifle bore with #9, leave it in for a day, push a patch thru, and repeat this process for sometimes a week or more. For longer storage, I use a good rust preventative, which Hoppes #9 is not.
If you live in an area with fairly low relative humidity, leaviing #9 in the barrel for a while is probably less harmful than if you live in a more humid place.
I'd ditch the #9 except for the short term, and use Break Free CLP or any one of the very good preservatives on the market.
For very long term storage you might want to consider even using a good grease in the bore.

For long term storage, a good parafin based preservative is good for long term storage. RIG is a good preservative which is parafin based.

It is the only thing that I have left in bores for many, many years. Some have been in unattended long-term storage without any ill effects at all. It works 24/7/365. It is great for pulling microscopic particles of powder and jacket material from the grain of the steel. There are better long-term protectants like cosmoline, but I don't store mine for 20 years at a time. DDR

Hi All,

My cleaning procedure for long guns is

1) Run soaked patch down barrel
1a) Use bore brush only if it really, really needs it

2) Clean bolt/bolt assembly

3) Run dry patches through the bore until one comes out clean

4) Lightly oil bore with a patch, followed up by a dry patch

Since leaving the bore soaking in solvent (in my case, Hoppes #9) seems to leech crud out from the metal, I'm wondering if it's OK, in your experience, to just leave a light coating of Hoppes in the barrel in lieu of oil?
My procedure is pretty much like yours, but differs in a couple of small ways:

1) Use bore brush if needed.
1a) Run Hoppes #9-soaked patch down the barrel and let it do its copper-solvent thing.

[Hoppe's dissolves copper, so the bore brush goes through before the barrel gets its application of Hoppe's.]

2) Clean bolt/bolt assembly

3) Run dry patches through the bore until one comes out clean

4) Swab bore with a patch dampened in CLP, and run more patches down the barrel while the CLP softens and removes carbon deposits. Do this till the patches come out clean.

5) Run a final CLP patch through the barrel and put the rifle away.

As others have pointed out, Hoppe's is an excellent copper solvent, but doesn't do much to prevent rust.

i don't use any solvent except hoppe's anymore, whether i'm cleaning for corrosive or not. never had a rust problem, and i live in a high humidity climate.
ultimately, what you use for cleaning is a personal choice, and you're gonna get lots of different answers here. anything from " if you don't use at least 50 gallons of hot soapy water, your barrel will rust through within a week", to my personal answer above. we all use what works well for us.

y'all have a good day, Keith

"How effective is Hoppes #9 after shooting corrosive ammo?"

Lots of folks with milsurp shooting experience will never use it only, because of negative past experiences with it. I can only tell you my experience with it. No problems using Hoppes #9 on any of my milsurps(for the past 11 years since I have been collecting and shooting milsurps) - The MN's, the Turks and any of the other oddball rifles I own all have not rusted up/corroded in the bore. I never use the water/soap method & I live in a very low humidty environment. If I lived in a high humidity area, I might have to change my cleaning methods, but to date no problems using Hoppes #9.

Pahtu.

Why use Hoppes at all, anymore? I have an old bottle of the Original Recipe Hoppes that still contains Benzene. It's a great powder solvent, but pretty marginal for effective copper removal. With newer & better cleaners available, the only reason to use Hoppes anymore is for the aroma.

Take a look at the Outers Foaming Bore Cleaner. The tiny can doesn't look like much, and it certainly doesn't smell very powerful, but pump some down the bore of your favorite firearm after you've already cleaned it with your current procedures and bore cleaners, sit back for 1/2 hour, then push a clean patch thru the bore. The dark blue/green goo shows you that there was a lot of accumulated copper you missed with your regular cleaning method. As for flushing out water soluble corrosive residue salts, the Foam will do it. Hoppes will flush out salts, but won't dissolve them. Some fight to the death defending Hoppes' corrosive salts removal capabilities, but the chemical composition of Hoppes indicates that it isn't nearly the best choice - why take the chance?

Better to Leave a thin film of GI bore cleaner in the bore, rather than Hoppes.

Add me too o the "nothing but #9" list.
I shoot all my firearms, some not so often but I eventually get around to them. Some might go a year to 2 between range trips at the most. Hoppes never allowed rust. On occasion if I remember about it and discover a gun has gone over a year - year and a half without shooting I'll run a couple patches through.
My house is air conditioned in summer so high humidities are not a concern.
Hmmm, come to think of it, there are a few I haven't shot in at least a year.

I use Hoppes #9 on all my military rifles to remove any fouling.

If I've been shooting corrosive ammo, then the barrels get a jug full of boiling water down the bore. I dry out the bore, and then run a patch down the barrel while the steel is still hot. This opens up the pores in the metal so the solvent can really get in deep. Most of the time I'll leave the Hoppes in the barrel for a few days before removing the nice green gunk, and then oiling the bore with M-Pro 7 Gun Oil, and wiping down the external metal with Rem Oil.

On my target and hunting rifles I use M-Pro 7 Bore Gel instead of Hoppes.

If I shoot corrosive ammunition, I perform the Empire Arms procedure at the range, and follow it up Hoppes #9 at home. Since I never know when that particular rifle is going to the range again, it gets a last swipe with RIG. The exterior metal gets wiped down with Ballistol. If I really know that it will be years before it gets touched again, the exterior gets Staples Crystal Clear Wax.

PS If the bore is really copper fouled Sweets or Hoppes Foam is employed before the RIG.

I have used hoppe's cleaner and oil for many years but now i'm using the orginal G.I. Rifle Bore Cleaner and G.I. light weapons oil. Either way I have never had a problem yet. I did notice that the G.I. bore cleaner will eat out the residue from rubber or plastic bullets too. :D

After shooting corrosive, I always use hoppes and finish with bore butter. Same method I use for my Black powder. Never had an issue with rust or corrosion.

Blue Wonder. It smells better than Hoppes :) It sticks too. More of a gel, like my son's hair:D
