Typically, I follow my regular cleaning routine but opt for a deep cleaning method once a week. Since using ReO2, I have found it to be far superior to my normal ultrasonic cleaner.

I've been wearing monthly contact lenses for over ten years and constantly feel dry and uncomfortable. ReO2 makes my contact lens feel as fresh as daily disposal, that's amazing.
