bigcraig Posted July 3, 2015 Share Posted July 3, 2015 Anybody rig up a bench top media blaster to clean their comp on an Open gun? If so, I've got questions for you. 1) What media material did you choose? 2) What pressure? I have an blaster that hasn't been in use for years that I can re-purpose for this dedicated task. Just looking for some insight from others. Thanks Link to comment Share on other sites More sharing options...
Tochnost Posted July 6, 2015 Share Posted July 6, 2015 I cleaned a trubor t-2 with 100 grit aluminum oxide at about 80psi. Worked perfect, looked like new. Link to comment Share on other sites More sharing options...
Nugget Posted July 6, 2015 Share Posted July 6, 2015 I would just be careful around the crown of the bore. Link to comment Share on other sites More sharing options...
bigcraig Posted July 6, 2015 Author Share Posted July 6, 2015 I have one of the new STI DVC open guns that has the TiN coating on the barrel and comp, I wonder how hard the coating is! I was thinking turning the pressure way down to like 30psi, and using baking soda to start, then maybe work my way up from there. Link to comment Share on other sites More sharing options...
Tochnost Posted July 6, 2015 Share Posted July 6, 2015 Let us know how it works out with the baking soda. I guess worst case you could have your barrel recoated. Link to comment Share on other sites More sharing options...
pointblanktx Posted July 7, 2015 Share Posted July 7, 2015 I too would be worried about the crown on the barrel. I guess you could maybe put a foam earplug in it to protect it some what from indirect blasts. Link to comment Share on other sites More sharing options...
BeerBaron Posted July 7, 2015 Share Posted July 7, 2015 yeah I don't feel comfortable media blasting my barrel/comp. What I've found works quite well is spray the comp (inside and out) with the hornady one shoot gun cleaner/dry lube (looks like like the one shot case lube cans). then any lead or carbon is easy to get off. It has to be clean first of course. I use the arredondo comp cleaning tool (kind of like a screw driver). Check what your comp is made of too. media blasting anything alluminium requires some care!!

sniper3 Posted July 7, 2015 Share Posted July 7, 2015 Has anyone ever tried putting the comp in a sonic cleaner. I've got alot of build up on my comps and I'm too afraid to put it in the sonic cleaner in fear of damaging the outside finish. Has anyone experimented with an old comp ??

Barrel and comp are a single unit on the DVC. I would obviously protect the barrel crown in some manner, shouldn't be too hard. I am actually more worried about damaging the metal than I am about appearance of the comp. I may dig up some old drill bits that have the TiN coating on them just to test, but knocking the finish off the comp wouldn't hurt my feelings, if it only took a few minutes to completely clean the comp. This will be a while, I have a ton of other nonsense going on right now. Link to comment Share on other sites More sharing options...
Glockinator Posted July 7, 2015 Share Posted July 7, 2015 What about tossing the comp in a brass tumbler? Maybe a bit less aggressive than blasting? Link to comment Share on other sites More sharing options...
sauza45 Posted July 7, 2015 Share Posted July 7, 2015 I use a sonic cleaner with 50/50 water and simple green, comp comes out looking new. Link to comment Share on other sites More sharing options...
sniper3 Posted July 7, 2015 Share Posted July 7, 2015 sauza45.....I assume you've tried it . Was the outside finish blue, nickel, chrome ? And did you use heat and for how long did you run the sonic cleaner for ?? Link to comment Share on other sites More sharing options...

bigboy69 Posted July 8, 2015 Share Posted July 8, 2015 Soak your comp in Weapon Shields Solvent and it will come right out Link to comment Share on other sites More sharing options...
sauza45 Posted July 8, 2015 Share Posted July 8, 2015 Yes I have done it several times, it is a chromed steel comp. I don't use the heat I just use hot tap water. The cleaner runs about 3 min a cycle and it takes about 3 cycles. In between each cycle I just take a q-tip and run it in the ports of the comp. I let it run as I clean the rest of the gun. This is with the Brazos T2 comp which is a barrel and comp in one. Link to comment Share on other sites More sharing options...

truborshooter Posted July 10, 2015 Share Posted July 10, 2015 sniper3 did you get a chance to sonic clean your comp with simple green? how did it come out? Link to comment Share on other sites More sharing options...
sniper3 Posted July 10, 2015 Share Posted July 10, 2015 Not yet. going to the range Sunday morning. when I get home I'll take it all apart for cleaning and stick the barrel and comp in the sonic cleaner. Still a little leary. If the outside finish gets damaged that means I have to send the whole gun out to be refinished. ( I'm pretty anal about the way my guns look and shoot ) Link to comment Share on other sites More sharing options...
sniper3 Posted July 11, 2015 Share Posted July 11, 2015 Ok , couldn't wait , so I tried it . And it does work and did not hurt the outside finish on the blue or the chrome comps ! . But wait . I did like sauza45 said ...... 50/50 solution ... 3 minutes per cycle .... 3 times. My comps had big "mounds" of buildup in them , so I used a small flat bladed screwdriver in between cycles to loosen the crud up . By the third time I was scraping big chunks off . Its going to take several more times at least , and a lot more scraping to get them totally clean , but its well worth it. sauza45 is now the official comp guru in my book. Thanks for the great tip !! Link to comment Share on other sites More sharing options...
sniper3 Posted July 13, 2015 Share Posted July 13, 2015 Just a quick update. After the range yesterday , I sonic cleaned the comps again, and alot more crud came out , but not down to bare metal yet. A few more times should remove it all. A little steel or brass brush would really help it along if they made one small enough, but still a great solution to a bad problem Link to comment Share on other sites More sharing options...
igolfat8 Posted July 14, 2015 Share Posted July 14, 2015 Soak it for a couple days in a 1:1 mixture of white vinegar and hydrogen peroxide. Dissolves lead build up safely. Don't get the mixture on you because lead is poisonous. Rinse clean with water. Don't bead blast the surface as it will make it surface porous which will give the lead more surface to cling to and make subsequent cleanings more difficult.

Don't bead blast the surface as it will make it surface porous which will give the lead more surface to cling to and make subsequent cleanings more difficult. I'm not sure I'd describe this approach as a method to dissolve lead "safely". The problem with this approach is it leaves you with a nasty mix of vinegar, hydrogen peroxide, and lead acetate which is extremely toxic. It's readily absorbed through the skin. Can it be safely handled? Yes. But you really should read up on it and know what you are doing. Google "lead acetate MSDS" and start reading on how to safely handle it as well as how to dispose of the liquid waste at the proper HAZMAT facility.

ipscjoe Posted July 22, 2015 Share Posted July 22, 2015 Outers foulout. Teflon:plumbers tape the comp and fill solution all the way up into the comp. Comes out like mud in hours not days. Link to comment Share on other sites More sharing options...
Dale Rader Posted July 22, 2015 Share Posted July 22, 2015 (edited) A 50/50 solution of vinegar and hydrogen peroxide works great as well. If the fouling is very bad, you may have to replace the solution to get it all removed. I just saw igolfat8's post. Sorry for the repeat!
