Barrel cleaning solvent?

[MarikinaMan]

I found Marvel Mystery Oil to be very effective at cleaning crud in the barrel. Soak it for a day and it will clean much easier. Ive tried Hoppes, CLP, MPro and this seems to be very effective and a helluva lot cheaper.

Just make up your own Ed's Red. Equal parts of ATF, kerosene, mineral spirits and acetone. Skip the acetone if around plastic parts. Can sub diesel for kerosene, but it smells more.

I have used 50/50 MMO and Hoppes #9 for a long time.

What he said^^^^^^^ is my experience too. I haven't found a need for anything else after I switched over to ER many years ago. I don't add the acetone in my mix.
