What’s in Lemi Shine? – UPDATED » Chemistry Blog
I just use Hansells Citric Acid from the supermarket, cheap as.
For my Ultrasonic tank which holds 5 litres water I use 1 teaspoon of Hansells and a couple of squirts of dishwash liquid.
For my SS tumbler, 7 litres water, I use 1/2 teaspoon of Hansells and a couple of overflowing caps of car wash liquid.
For either method you don't need to add much. The big mistake, certainly with the Ultrasonic is adding too much citric acid which attacks the brass alloy.
