Instead of Lemishine I use bulk Citric Acid I buy off eBay. Most of it goes into the kitchen dishwasher, far cheaper to buy it in bulk than in the little Lemishine containers in the supermarket. Only a tiny amount goes for brass cleaning. The lone advantage for using Lemishine is that it has an anti-caking agent. I have to store the Citric Acid in a gallon milk jug with a screw lid to keep it from caking badly. For brass cleaning I make up a water solution of a couple of tablespoons of CA in a gallon of water and add a little bit of dishwashing detergent like Dawn. Cases don't get shiny, but I don't care.
