Cleaning the reciver

RabidPitWeasle · 05-15-2007, 12:00 PM

I pulled the CETME apart today and wanted to give it a good cleaning,after running about 200rds trough it.
After I get the stock off and the bolt pulled out I tried to clean the inside of the reciver, but can only stick my fingers so far. They tend to get alot of buildup of carbon.
Whats a good tool to get in there to clean? I thought about a brush of some sort.

I generally use automotive brake cleaner.

Old rag strip wrapped around a shotgun rod and tip, and lots of good bore cleaner.

Works for my Spanish Lady!

Old toothbrushes work well also.

When using solvent cleaners, get ones that say "residue free" or "no residue", unlike most brake cleaners, as the residue they leave is usually a white almost powdery substance that can't be good for the gun. I use CRC Electromotive cleaner that is designed to clean electrical connections.

My Spanish Lady is all clean inside, even after shooting through about 80 rounds of Wolf; man that stuff is dirty, but it shoots well enough for plinking!

CETME fluted chambers absolutely MUST be cleaned of ALL grease, cosmolene, dirt, carbon, etc. It's not easy but must be done. The flutes aid in extraction of fired shells. Factory manual recommends ONLY VERY LIGHT OIL in chamber, like 1 drop on patch!

ill use a 37mm flre launcher brush,cost cheap and work's wonder's

A .40 cal brush with a patch wrapped around it soaked in gun cleaner works for the chamber.

For the "outer chamber" where the rollers lock the action closed I ended up getting a set of dental picks for scraping out the little nooks and crannys.

+1!

This worked great to get out the crud in the flutes! It's handy that I already had a .40 brush for my G27.

I found Gun Scrubber sprayed right in the chamber works well (at $4.00+ a can. But.. Starter Fluid does almost as good, ($1.00 a can on sale at Schucks). As it totally evaperates and leaves little to no residue. I do it muzzle down and spray it until it runs clear out of the barrel.. It even makes punching the bore easier.. Patch is clear after three patches.. (Course, using my Dewey with a Hoppe's saturated bore brush 1st)..

I agree Seattlefungus, the high-volitile spray cleaners are great, due to their organic solvents (carb-cleaner, electrical parts cleaner, fuel injector cleaner) and even better if you get one that says "leaves no residue" right on the label.

Problem is, there's absolutely no oils left on the metal once you're done and you need to get some gun oil on there pronto or you'll start to see surface rust on any non-parkerized/blued/tennifered/etc... metal.
