CLR

Thanx swadiver. I use Gun Scrubber, and figured IF I try the CLR whether that would do the trick. GS seems to work on everything else without harm.
 
I left it in my Swift barrel 10 minutes the first application, and what looked like brown mud came out on a clean patch. The next patches had black carbon on them that I could peel of the patch. I did scrub the throat with a brush with clr on it, and although I don't have a borescope, I could see the throat area was much brighter and could see land and groves much better. I'll shoot it this week and see if it improves. I tried it on my Swedes with similar results. This stuff works. Barlow
 
Is this military issued CLR or commercial? I've got a gallon of military CLR , 2 actually, opened one . It smells a little like diesel oil
 
After reading about CLR removing carbon I bought a bottle, tried aggressive scrubbing with a tight fitting brass brush followed by borescope imaging. I was quite disappointed as it was largely ineffective for removing carbon.

Maybe the formulation has been changed? On the lower right front label it has a logo stating "Safer Choice" "Meets EPA Safer Product Standards"

My jug is labeled the same. Barlow
 
from the clr calcium lime and rust MSDS. don't think i will be using it.

Restrictions on Use Incompatible with strong oxidizing agents, metals (except stainless steel, chrome),
acids, bases, and bleach...

I just finished trying CLR on what I thought was a clean barrel , Sweets is about the hardest cleaner out there . I never let a new cleaner soak at first , this CLR after putting some on a patch and running up an down in the barrel I was surprised to see the patch come out saturated with carbon .

I dry patched then ran another with CLR patch came out clean , finished dry patching to remove any traces of CLR , went to old faithful #9 then dry patches.

Sunday is my bench day , well see how it shoots . Didn't have a problem with the barrel or groups , I just find my rifle shoots well clean . thats the only reason I gave CLR a try .

P.S. ratbuster
What bullets are you shooting ?
Are you sure it's carbon left in your barrel ?
How often do you do you clean your rifle ?
Don't want to seem like a know it all but I thought CLR wouldn't do much either .
I give my barrel a good cleaning everytime I shoot , I was amazed the amount of carbon
left in the barrel.

To answer your questions...
For my target rifles I use naked Berger bullets
Yes I'm sure, I have a borescope
I clean EVERY time I shoot, even if only a few shots. I typically use Boretech products: C4 Carbon Remover and CU+ Copper Remover but I have tried many types of cleaners. I am an advocate of tight fitting brass brush scrubbing and am not afraid to use Thoroclean (Iosso solution) or Iosso paste if Boretech does not get the job done. I do not like dirty bores and do not let carbon build up.
I will give CLR another try but I was thoroughly unimpressed after my first evaluation.

When it comes to cleaning Im with you that's why Im sure we both gave it a try . I didn't let it soak , the patch was pretty wet , one good scrub back an forth maybe seven times an the patch came out brown . Im using the Parker hale jag , the patch is wrapped around the jag giving me alot of cleaning surface , and the whole Patch came out brown . Second goround the patch was pretty clean . Try giving it another shot . I don't own a bore scope to really see inside . When you tried it dd the patch come out clean ?
Without looking with the scope I could have carbon still in my barrel . Before using the CLR I thought my barrel was clean , I've used KG-1 & KG-12 followed by #9 Tried wipe out - patch out followed by #9 JP Compound & Kroil followed by #9 Even Ballistol followed by #9 , which worked the best . Then came CLR . It's my first goround with it . Will see how it goes . Good Luck , let my know how you make out .

Chris,

I wet the barrel with CLR soaked patch then scrubbed about 12 in and out strokes with a tight brass brush and more CLR. Dry patches followed by the borescope. My conclusion was CLR is ineffective as a hard carbon remover. Of course it will work great at removing powder fouling but so will water.

An assessment of what works by looking at patches is not a reliable way of knowing what progress is being made in the bore.

I agree 100% a good borescope is up there in price. Not in the position to to buy one , so I will relay on what my patches look like for now . The borescope is the real check on what's happening in the barrel . Nice talking to you . Be Well .

Chris
 
i just did a test with the new batch of CLR,the one marked "eco friendly". the borescope said it was not good at removing the carbon deep in the grooves. re cleaned with the homemade concoction of Bon Ami cleaning powder mixed with Hoppes #9 and a bit of Mercury Outboard Quicksilver Power tune, way better job at deep carbon removal. i am done with CLR

Chris,

You can get a lyman for under $200.00. While it does not have the resolution of a Hawkeye it is good enough to evaluate a bore for nearly all needs except 17 caliber's. In fact I have an extra one that is in excellent condition I'll sell for $140.
