There are better, more efficient and safer products than ammonia based Sweets 7.62.
For one, have a look at the BoreTech range like Ellimator. No ammonia and safe to leave soaking if you wish, even leave a fine coating in your bore.
I have a bottle of Sweets that has not been used for years after I did a test. Cleaned a bore as best I could then Sweets until noting showed on a patch. Then I ran some BoreTech Eliminator through on a patch....more copper....so I decided that the Sweets was just not good enough.
