I use Dawn and lemon shine most often (dozens of loads) and then vibratory tumble with corn cob and flitz for high shine and long protection.
If I’m NOT going to dry tumble then I use their special sauce cause it does seem to protect from tarnishing.
Regardless, mine is still going strong even using Dawn and lemonshine.
You Sir win the Good Housekeeping Seal of Approval for the Cleanest brass ever!
The burning question for all the wet tumbler users, what are the nuances of cleanliness between DAWN and any other dish-washing soap.? Has bds (Live Life) done a statistical test on this yet?? Is Dawn Platnium mo betterer?
