If you don't need it, don't use it. What brand(s) of brass are you using?
Like you, I do a mid-cleaning water dump but I used Lemishine on both sides of that for years. It is still used by more people than not, though where they are buying it, I don't know.
Try the wood bleach sometime - about a heaping teaspoon in my 1-gallon tumbler. I will run up to about 130 cases of .45-70 at a time. Sometimes a little more, maybe.
I clean smokeless the same way, but it cleans faster and without the mid-cleaning water change.
Right now, I'm loading my truck with 438 rounds of .45-70, 200 each of .38-40 and 38-55, 50 rounds of .30-40 (recreational plinking stuff), some .45 acp (also recreational), 1000+ rounds of .22 Eley TenX and Target, 200 rounds of 12 gauge (recreational), and probably some other stuff that I'm not thinking about. I'll be off to Raton in the morning for 3 weeks.
When I get home, there will be a pile of brass cleaning to do.
