Yes, I have tried it but unless you heat the barrel you will never empty the pores + the heated pores really helps the Dyna-Tek get into the pores in the bore.


And according to the MDS sheet there are petroleum additives in Brake Cleaner and that is what I am trying to get rid of...


Additionally the boiling water removes all plastic fouling without an effort at all. Just got to get the bore completely dry with air than while the barrel is very hot apply the Dyna-Tek.

??? There's no petroleum in Brake Cleaners. It's made to eliminate petroleum based products such as grease and brake fluid from disc rotors. I've used it several times for degreasing prep for bluing/browning barrels. Never used that dynatech stuff before so I have no knowledge about the heated pores accepting it better but I can tell you without a doubt there is absolutely no oil residue left after using brake clean.

Good product,just got to make sure it's not expired otherwise it's not working. I've removed it from all my ml'er bored and just use a good bore oil or grease.

Technically, practically everything on this list is a "petroleum product".
Except carbon dioxide which is the propellant gas in the aerosol can.
Methanol,aka wood alcohol,aka denatured alcohol can be produced by the destructive distillation on wood but probably is produced by reactions that start with simple hydrocarbons. All the others can be recovered from crude oil not that would be the best way.
What they are is a mixture of low molecular weight compounds that have low boiling points and will evaporate quickly. As they wash across a surface they will dissolve heavier oils (& greases) and flush them away.
This too long already, but I could fill a couple of pages with info on polar/nonpolar solvents and the solvation process.

Try nonchlorinated brake cleaner instead. Its around 50% acetone/toluene and less than 3% naphtha.

Personally I have used Carb Cleaner more than Brake Cleaner swish out a bore. I think either product in the normal circumstance works well.

Looks like you got it "cooked" just right. The nice looking rifle sure does shoot well.

Hoping to run out this afternoon to do one more verification... I will shoot some more birds but I, at this point need to shoot a paper target @100 just to verify what I think I know

Plus since I will be shooting T7 it should tell me if my Dyna-Tek project really worked..
