Montana EXtreme Product - Gone?

Fire Dog said:
You bet, and NEVER leave Sweets in your barrel for more than 15 minutes {ammonia based solvent which Montana Extreme is as well} and be sure to lightly oil bore before storing otherwise it may look like you used corrosive ammo in it…
Bore Tech all the way on my bench… CU+2 & C4 along with a bit of their Extreme CLP
Even left over night it does the job without any damage or stink…
The originator of Sweets died a couple of years ago but his daughter has kept the business going… I have a bottle of Sweets & Hoppes Bench Rest No.9 just sitting in the cupboard that has only been used once before reverting back to BT CU+2…

Reading your admonishment about not leaving Sweets in your barrel for over 15 min. I have been leaving it my barrels overnight or morning to evening for about 40 years with only great results. Maybe my Sweets is different than yours. I have a couple of mostly useless bottles of BT sitting.Maybe we could trade, lol.

Try Precision Reloading, it was on their web-site yesterday (3/9/26).
 
I called again today… Montana Extreme has the nicest lady answering the phone… she said the same thing about the chemist and went on to say something needed is back ordered. No ETA provided..

If you pay the postage I will give you the bottle..
It is after all an Australian product.. {:~).
The admonishment about not leaving it for more than 15 minutes is item #5 on the back of the bottle.
If you can make it to the Pima County range off of I-10 some time in late June I will hand deliver it…

Never heard of Pima County, is it in the US, lol. Ok think about this. Its going to take x amount of exposure time for the copper to be desolved. If your selling it and its going to take say 8 hours of exposure, do want the end user to use one patch or 32 patches of your product?

Good. Your probably have dryer weather then us. Rained off and on all day and for the last several hours pouring. Sweets is pretty good at cleaning copper, best I have found.I have made a lot of faces get long when I proved to guys just how much copper they were not getting out of their barrels. That and Hoppes take care of my cleaning along with Iosso for hard carbon.But, hey there is an entire Industry built around cleaning firearms.I laugh at some of the products folks think are cleaning theie guns, testing them multiple times, they are doing virtually nothing. So be it.
.
 
I used ME to clean up some old barrels from the pawn shop, along with a brush and plenty of elbow grease it worked about as good as anything else so basically no complaints but no real surprise on how well it cleaned either.
Could be my application of the product also.
 
Fifty years after I bought my first bottle of Sweets 7.62, I'm still a fan every 100 rounds or so. At matches I run the GM Top End cleaner every relay. Sweets at the end of the day.
 
There are only a few chemicals that dissolve copper without dissolving steel. Ammonia is the one that makes the blue color. Adding Hydrogen Peroxide speeds the process a bit. So basically most of the gun copper solvents are just ammonia. They all work the same depending on the concentration they use. Sweet's is 5 to 10% ammonia.

FWIW, I like using Wipeout foam and just let it sit.

KG12 works fast enough that you can see the copper go away. I don't know what the base is. Since it does not change color there are two probables:
1. Sodium persulfate (the stuff used to etch printed circuit boards).
2. Ferric Chloride works really well, but, it can also etch steel if exposed long enough.
It might be ferric chloride since it works so fast. Could be why they recommend leaving it in the barrel for only 30 seconds.
