My routine is plain hot water rinse when needed and several times a year I dawn wash then pop in the UC for a couple cycles. I used to be pretty .... about cleaning weekly but that has long since passed. My dts are the only thing I clean whether needed or not these days.My issue is, after a soaping, I still find residual soap aroma lingering, no matter how many rinses. Guess an ultrasonic cleaner would help that.
