-Dexron automatic transmission fluid<br>
-Kingsford charcoal lighter fluid (Stoddard solvent) or odorless mineral spirits (aliphatic mineral spirits)<br>
-and add... 2 oz. of acetone
Mix and store in a metal can (I use an empty quart chemical can)
You can use 8 oz (equal parts) of each but you don't really need that much acetone to soften plastic wad residue. A lesser amount works a bit slower on the plastic but makes it smell less strong when used indoors.
<blockquote><I>"TeeJ: And you get that where? Window Cleaner that disolves plastic?????"</I></blockquote>Rutland Glass Cleaner is made to clean the glass doors in wood burning stoves. It has a lot of silica (very fine sand) in it so it acts like scouring powder to remove soot deposits (Remington markets a liquid bore cleaner that has something similar in it). It's probably something like Soft Scrub Cleanser.
I don't know how effective it would be at removing plastic residue. This stuff also leaves a deposit of silicone behind, supposedly to make the next cleaning easier. I'm not too sure about that one. It's not supposed to scratch glass.
I'll stick with Ed's Red! Getting that grit in the ejectors/extractors sounds like a bad plan to me.
PB Blaster used alone is a great bore cleaner. PB Blaster is a nut and bolt freeing agent used to spray upon bolts and nuts that will not break free. Somewhat like Liquid Wrench but a bit better IMHO. It comes in an aerosol can and you can find it at AutoZone or Advanced Auto Parts or Pep Boys.
I used to make up Ed's Red and changed the formulae to drop the Kerosene and replaced that with Kano KROIL. A bit more expensive but boy does it work better. KROIL is a super penetrating oil that does a great job in cleaning and loosening metal parts. It also puts up a nice anti-rust barrier. All the modern benchrest shooters have been using Kroil for years on their expensive barrels.
So now a days I use PB Blaster on the barrel cleaning and follow that with a patch of KROIL for final lubrication.
BTW, to clean a really nasty barrel (say on a used shotgun)... that Cyclone wire brush just is hard to beat.
What is the Dextron for? Just wondering because I have a 5 Gallon can of Traveller Universal Tran/Hydra oil. Use it on tractors that share the transmission and hydraulics oil. Wonder if it would work in place of the Dextron?
Here's what the originator of the formula said about DEXRON (no "t") and its use in Ed's Red: <center> View attachment 213625
I don't know which 2 components are "polar" and which 2 are "non-polar", but he did. I know that there are transmission fluids that are quite different from each other chemically (Dexron and Mopar, for example), so I can see no reason to change the formula by substitutions from the way it was developed. You are free to make your own decision about that.
