i have a new frameless mask that i have cleaned with toothpaste, soft scrub and i also flamed it. i use defog or spit every dive but it still fogs every time. i would like to try to clean it with an ultrasonic cleaner but i need some advice. i have a crest 275ht machine. my questions are...what solution should i use, should i use the heater and how long should i clean it. any help would be appreciated. thanks.
