I’m adding less than 1/2 ounce (1 tsp) of citric acid for the occasional load of soap dishes. Based on testing with pH strips, 1/2 ounce CA in 2 gal of water drops the pH to 5.5 from 7. I think my dishwasher uses 4-5 gallons of water per load. Newer dishwashers may use less water.
The manufacturer of my dw sells a citric acid based product for descaling (frequency not given) and a washing soda based product to clean the dishwasher (cleaning is recommended every few months).
