I use CLR in mine and I mix the CLR 1 part CLR to 5 parts water. I let the solution warm up for five minutes before putting the tuner in. Keep a close eye on it as the CLR can damage plated surfaces if left to long. I also hang on to it with pliers and swish it around while its in there and I go for 15 to 30 seconds and then rinse in fresh water. Blow the water off with some compressed air after and you will be good to go.
