I'm not sure if this is where to post this question so I will try this section. I just picked up a used G35 Gen 3. It has THE WORST lead fouling in the barrel I've ever seen and nothing I've tried will remove it. I've used Hoppe's Elite with great success, on all my other firearms, but it won't budge this fouling and neither will Eliminator. I even put the barrel in my neighbors ultrasonic cleaner for 40 min and that didn't help. Any suggestions would be greatly appreciated.

Im no expert, but I think you're screwed. Due to the polygonal rifling, you're not supposed to shoot lead through Glock bbls. I think you were had by the previous owner.

Buy a Lone Wolf threaded barrel and a suppressor.

I've had good luck with Chore Boy copper pads & Hoppes to remove bad fouling in my Ruger 454 Casull. Use a wad of it on the end of your cleaning rod. I have no idea if it'll work on polygonal rifling, but it's worth a try. It certainly can't hurt.

Make sure they're pure copper pads.

You're fine. People shoot lead in Glocks all the time. Go read glocktalk


Lewis Lead Remover works well, and some folks like to use Chore Boys with a brass brush, and vinegar/hydrogen peroxide mixes do well also but keep in mind that concoction will also eat away any bluing. Maybe won't hurt a Glock barrel's finish too badly, though.

*EDIT* delliottg is faster @ typing lol

New barrel and call it good.

you could also try some heat to soften it up, loosen the bond

lone wolf is your best, quick remedy. Glocky no likey lead...... and that kind of buildup is not gonna come out with a little "solutution"

Id work it hard with some quality bore brushes (the wire is stiffer and lasts longer) its gonna take a while. May be able to sand blast???

If you dont want to try cleaning it out you can send to me, I love glocks and love a challenge.....and i dont own a 35 so your safe and may get it back

Lead melts at just over 600 degrees fahrenheit. I cant imagine getting near that point will damage the barrel.

Im not an engineer nor a metallurgist and im assuming the barrels have some temper or hardening and im not sure 600 deg is gonna be good for the barrel but what do i know???

let the metal masters chime in

Honestly, I also have no idea. 600 just doesn't seem hot enough to damage the barrel. In my completely uneducated opinion.

stick a blow torch down it for a few min. brush it out

I have an older one and these are the best lead removal system I have ever used. You plug the barrel, insert rod with O-rings, fill with solvent and attach wire to the barrel and the other to the rod, plug it in and the lead is electromagnetically drawn from the barrel to the rod. takes a little time but it will remove every molecule of lead.

I periodically clean lead fouling from my competition revolvers as I shoot almost exclusively cast lead bullets. My technique is either a Lewis Lead Remover or, a cheaper alternative, to take a cleaning rod and bronze brush, insert from muzzle end through to chamber, wrap bronze wool (or fragments of Chore Boy pad) around the brush, then pull back to force through barrel. These are mechanical methods of lead removal and take some elbow grease though effective.

The other method you could opt for is chemical removal. I saw one of the other posters recommended the Outers system though this is discontinued and no longer available in retail channels from what I've seen. A last ditch alternative is The Dip (hydrogen peroxide & vinegar solution). I would research this before trying it if I were you. The dip will chemically remove lead from the bore (or suppressors) but results in a nasty lead acetate solution that can absorb into your bloodstream directly through your skin. Take proper precautions. You could always store the end solution in a glass container, label it, and take it to the Hawks Prairie HazoHouse in Lacey for disposal.

One final note. To minimize my risk of lead ingestion after any lead handling (gun cleaning, reloading sessions) have recently started using D-Lead Abrasive Hand Soap by Esca Tech. Keep it by my garage sink. I also keep smaller bottles in my range bag and wipe up after range sessions.
