What does everyone think of this carbon ring removal method

[biggun2869]

I wonder how a case, with teeth cut into it, will reach the spot that brass never reaches and lets carbon build up in the first place?
I bet this was posted from a cabin with snow blocking the door and never actually tested.

It is going farther in on the wood dowel. I read something similar in PS with a cut off .22 case. Yhe particular rifle was a 541 Remington

I used to use Iosso on an oversized bronze brush. I would attach the brush to a short cleaning rod, and lock the brush to the rod with an 8/32 nut. this way I could rotate back and forth in both directions without the brush loosening up. Without a bore guide I would insert it only enough to reach the end of the chamber neck where the carbon ring is. This method worked but Iosso is a bit abrasive and I don't like using abrasives in the barrel especially near the lands unless it is absolutely necessary. I then tried Chevron Techron fuel injector cleaner, which works really well on carboned up injectors but it didn't work too well on the carbon ring. What I have found to work really well is SEAFOAM which is used to clean caked on carbon deposits from engine valves. It is available at almost all auto parts stores and comes as a liquid and an aerosol. I use the aerosol and spray some on the bronze brush before I insert it. I then rotate the brush back and forth about 20 times and check with the bore scope. Most of the time one application gets it. If the ring is badly built up you may have to spray some into the chamber (the can comes with a long thin spray tube attachment) and let it soak before brushing. Seafoam also works great on a patch to remove carbon from the barrel and it is cheap compared to bore cleaners. (By the way I do use it on my cars to clean the valves on engines with direct fuel injection and it works well there too.)

I use SEAFOAM in all my seasonal stuff , mix 1 oz - 1 gal of gas. And use a lot of it. It's 1/2 price if you buy by the case on evilbay.

Just soak a patch with BoreTec C-4 and insert it until you feel it drop out of your bore guide. Leave it sit for 10-15 minutes then brush with a bronze bore brush. Works for me.

I use mercury tune it works great just like the evinrude brand it gets it out for sure.

Cheers Trev.

Sounds to be like GM Top Engine Cleaner. Beware the main active ingredient is rather naasty and is DEF a known carcinogen.

This was posted back in 2005 as a way to remove a carbon ring. There were no comments at the time on it. Originally posted by member LongRanger. What do you think? Good way or not, is it possible to damage the barrel?

Verbatim

If you have or suspect carbon buildup in the small space between the mouth end of your case and the end of the chamber it can quickly be removed mechanically. Have used this trick for years.

Take a fired case and cut a series of small, pointed notches in the lip with a Dremel cut-off disk. Use the same cut-off disk to cut the neck off at the shoulder. Glue or force-fit the neck onto the end of an appropriately- sized wood dowel. Run your new cleaning tool into the chamber, by hand, until it stops. Give it a light twist or two. Remove tool and clean chamber. Carbon gone.

An aluminium rod cut to -.001 or .002 under neck diameter then slotted on the end so as to make teeth like the above brass case works great. A few turns removes a stubborn ring, I sharpen it once a year by setting up in the lathe and taking a cut on the face.

Put 30 cal brush on chamber cleaning handle and brush ....
Sheesh ....
