Last nite, tis was how i cleaned my copper / brass mech mod.
(I was told to use Tamarind paste + salt + water by my mom - 1st try)
Amazingly tis old method really2 works wonders. It cleans better than my regular soapy cleaning solution i often used. I probably dont need to polish those mod since all shines like new now.
1. Disassemble my mod.

Also, i was told that lemon + salt + water or Tomato sauce/ ketchup could clean as well.
I some times use colgate, ketchup or vinegar. I heard coke also can pakai. Whats Tamarind by the way?
