Do I need to do anything in particular to neutralize the ammonia after cleaning.

I decided to use some Sweets 762 on my AR15. Man! there was a ton of copper fowling in there. I normally just use some M-Pro 7 but starting to think it doesn't get copper out as well as they say. It was just blue patch after patch after patch. At first I wasnt even waiting more than a minute after a Sweats patch. Then I started letting it sit for ten minutes and blue after blue after blue patch coming out.

So the first question is should I do anything in particular to neutralize the ammonia? What i did was after many blue patches I just clean/rinse/douse it with M-Pro7, dry patch a couple times, oil patch then a dry patch again.

P.S. I also realized that all the goopy blue gunk can get deposited in the muzzle device and get picked up by exiting patches causing me to think it was still dirty. Which it was. So to make this tale even longer; after I rinsed and cleaned the blue junk out of the muzzle device and from around the end of the barrel I verified the patch was no longer picking up any blue.

Then I ran more Sweats through it and got a bunch more blue patches. Took a hella long time and many rounds of Sweats before the blue went away. I clean regularly but this rifle has thousands of rounds down the barrel.

You got it. A couple dry patches, then couple of MPro7, then a couple dry and you should be in business. I always to a bore snake as a final pull through because it has a lot of surface area in contact with the bore.

Ammonia is a strong base so, technically, you would need an acid to neutralize it to pH of 7, but wouldn't travel down that rabbit hole with a precisely machined rifle bore.

To remove Sweets,
Denatured alcohol works fine, followed by a light oiling.
Vietnam era U.S. military GI bore cleaner works fine,
Kerosene works fine. (GI bore cleaner is a large part kerosene. )
Then dry patched,
then light oil and dry patch again.

This has worked for me.
And, I found out the hard way, what Sweets can do, if you dont get it out, and leave it too long, in the barrel... pits and etching... new barrel...

How about IPA or white vinegar or anything else a domesticated household would generally have on hand?

Kroil!!! Use it liberally.
Dry patch and shoot.
Spend more time shooting and less time cleaning.

Fleet enema works better. Has a special nozzle for delivering flushing goodness to the breach.
