drysideshooter Posted December 27, 2011 Share Posted December 27, 2011 Are there any chemical solutions that any of you have found to work well to soak a comp in prior to mechanically scraping the build-up? I have thought about trying a soak in Shooters Choice or something similar prior to scraping. Quote Link to comment Share on other sites More sharing options...
Chills1994 Posted December 27, 2011 Share Posted December 27, 2011 Is it made out of stainless steel? Quote Link to comment Share on other sites More sharing options...
Guest Posted December 27, 2011 Share Posted December 27, 2011 Mercury is a great lead remover and I remember my Father cleaning barrels with a bottle of mercury (Hg) that he kept locked away from us kids. I used it a couple of times in a .45 comp gun to clean the comp and it worked really good. Nowadays that would probably get you a Haz Mat and a SWAT team at your door! Not a recommended method unless you have a chem lab with all the hoods and such. I've also soaked the whole barrel with comp in a bore cleaner (shooters choice? Hoppes? don't recall now) and it made the loctite holding the comp to the barrel not lock tight any longer. Had to remove the comp, clean the threads of the goo and re-install. Now I just use swabs with a bore cleaner and then nut picking picks and dental tools. Quote Link to comment Share on other sites More sharing options...
TMC Posted December 27, 2011 Share Posted December 27, 2011 Equal part of vinegar and hydrogen peroxide. Works great on stailess steel and it not friendly to carbon steel. Quote Link to comment Share on other sites More sharing options...
Chills1994 Posted December 27, 2011 Share Posted December 27, 2011 ^^^ that is what I was going to recommend. 50/50 solution of vinegar and hydrogen peroxide if....IF! it is a stainless steel comp. I would imagine a carbon steel comp would turn orange with rust pretty quickly. I can't say or don't know what that concoction would do to an aluminum or titanium comp, though. that solution works well with suppressors made out of stainless too....so I have heard. especially if it is either impossible to take apart the suppressor or if it is a major PITA.

Dis-1-Shooter Posted December 27, 2011 Share Posted December 27, 2011 Not to drift the tread, but I use a small hand held sand blaster from Harbor Freight with some fine media. Mask the comp with duct tape and spray at a low air pressure. Quote Link to comment Share on other sites More sharing options...
gng4life Posted December 27, 2011 Share Posted December 27, 2011 Here is a good thread about this earlier this year. I remember reading about the Dillon case lube and thought about it again so I found the thread, good reading: http://www.brianenos.com/forums/index.php?showtopic=106910&hl=%20comp%20%20clean%20%20dillon&st=0 Quote Link to comment Share on other sites More sharing options...
MoNsTeR Posted December 27, 2011 Share Posted December 27, 2011 30 minutes in vinegar/peroxide did no visible damage to my titanium comp. Of course it didn't actually remove much crud either but it did more than any other chemical I've tried. One of these days I may try soaking it longer.

bigstick0000 Posted January 1, 2012 Share Posted January 1, 2012 harbor freight has ultrasonice cleaners cheaper then anywhere else I have seen. Looks like the same one i see in the gun mags, only cheaper and works great. Quote Link to comment Share on other sites More sharing options...
Sarge Posted January 1, 2012 Share Posted January 1, 2012 I'll second the bead blaster method. My gunsmith blasted mine this year and i thought he put a new comp on! Quote Link to comment Share on other sites More sharing options...
Whoops! Posted January 1, 2012 Share Posted January 1, 2012 I second the Ultrasonic Cleaner. I can't believe I spent so much time cleaning by hand while these babies were available. Put the parts in the recommended solution, turn on the machine, dry the parts, oil, done. No barrel swabs, no hazardous crap all over one's hands.

nipplehead Posted January 1, 2012 Share Posted January 1, 2012 Is there and danger to the barrel or its crown using a bead blaster? And what effect would the ultrasonic cleaner or its solution have on the loctite that bonds the barrel and comp? Quote Link to comment Share on other sites More sharing options...
Bigpops Posted January 1, 2012 Share Posted January 1, 2012 Why risk messing up your comp with home-made chemical combinations? Is it really that bad? Shoot it clean and give it a scrape once in awhile. I have tried the Dillon Case Lube trick and it really does work. Steve Quote Link to comment Share on other sites More sharing options...

Imagine a 2mm thick deposit of hardened carbon and melted jacket material. Getting that out involved a hammer and punch, and it's still not clean. A chemical soak that actually worked would be a lifesaver. Quote Link to comment Share on other sites More sharing options...
rishii Posted January 3, 2012 Share Posted January 3, 2012 I had an outers foul out just for cleaning my comp plugged both ends, chucked in the vise horizontally and poured the solution in the comp it took hours, but it turned the crud into a soft goop Quote Link to comment Share on other sites More sharing options...
Whoops! Posted January 3, 2012 Share Posted January 3, 2012 And what effect would the ultrasonic cleaner or its solution have on the loctite that bonds the barrel and comp? I use the "Hornady Ultrasonic Solution for Gun Parts" and it has no effect on my loctited screws. All the barrel and comp assemblies I used in it did not use Loctite.

Graham Smith Posted January 3, 2012 Share Posted January 3, 2012 Well, folks I know who shoot a lot of AR's swear by Evenrude Marine Engine Tuner. It's a spray foam and you spray it on things that have carbon build up and let it set for a few minutes before brushing or scraping. I've seen it work wonders.

Smokin Posted January 5, 2012 Share Posted January 5, 2012 I ran my comp and barrel in my sonic cleaner using the hornady solution for HOURS with "so-so" results. I do know that when you add vinegar to the solution, it works better, but am concerned about galling so I've stayed away from that. Quote Link to comment Share on other sites More sharing options...
