The OptiFix Pro Refill Kit will help prolong the life of your OptiFix Pro. It can be used with all OptiFix Pro ET devices (see the bottom of your device to ensure it states “OptiFix Pro-ET"). The refill kit includes 1 oz. cleaning solution, 1 ml. repair solution, one set of cleaning pads, and one set of repair pads. This is good for an additional 20-25 cleaning cycles and 15-20 repair cycles.
