as for Hoppes and modern plasic guns i dont see a issue ....

Been using Hoppes on my USP40 since day one, and 5k rounds later no issues. Maybe HK just makes a superior polymer.

i thought i read a post by you that you dont own a HK USP40 when folks where asking what you where selling to pay them back ?

. As much as I do love guns I'm not sitting on a private arsenal. Just because I like HK's doesn't mean I can afford them. That is not my HK USP Expert in my sig line nor is that me holding one with a thumbs up. They're pictures. http://www.calguns.net/calgunforum/s...&postcount=942

Hoppes # 9 is over 85% by weight of kerosene, ethanol, oleic acid and amyl acetate. Nylon 6/6 is highly resistant to these chemicals, even at higher temperatures for prolonged periods. So Hoppe away.

Plated metal parts have a slight risk because of the 3% by weight of ammonium hydroxide (used to remove copper fouling) as it will attack nickel as well.

So using Hoppes#9 to just clean the barrel of copper fouling would be okay? This is all I use #9 for with Hoppe's Elite cleaner (supposed to be non-toxic) for all other cleaning.

What is Polymer? Oh it's PLASTIC! And Hoppes comes in a plastic bottle, so it will harm plastic then they would use a glass bottle instead

QFT!

Were all arguing points and it comes in a plastic bottle LMAO!

It's tactical Tupperware, so just stick it in the top rack of the dishwasher!

Unless your instructor was a Chemist familiar with both the formulation of Hoppes and the Glock polymer I wouldnt take his advice as gospel. I use it on my USPc all the time, but that is an H&K

Exactly. LOL

Reminds me of a friend who I was with at the state fair a long time ago; some vendor was trying to sell us a penetrating oil similar to WD-40. He said this stuff will loosen stuck bolts, pentrate anywhere, nothing can stop it! My friend asked him, how do you keep it in the can?

Been using Hoppe's since the 90's and have never had a problem.

[otteray]

This is correct. They haven't used benzene in Hoppe's #9 for many years now.

My old bottle finally ran dry.
I sure miss that banana and nitro-benzine aroma now.

I guess that "over time" translates to greater than 15 years.

There are 2 kinds of plastics, thermosets and thermoplastics. Most solvent bottles are made from polypropylene. It has good resistance to most common solvents and acids. It has a high molecular weight but is very light and easy to synthesize.

Again, kudos to you for your open-minded approach. Also, sweet knife!

[NikePenguin]

Yes, it needs no cleaning. It's a Glock!

Glock's marketing campaign at the time I bought mine claimed it didn't require cleaning. So I didn't. And rarely do. I bought it with the full intent to abuse it.

Because its convenient, and works well.
But I don't soak down the frame...dip in a toothbrush, brush the frame/internals, and wipe down with a patch, then wipe down again with a slightly oiled rag, call it a day.

This is exactly what I do too. I don't soak my alloy frame just a little on a toothbrush, wipe, q tip, wipe,oil, wipe, done
