ACTIVE Ice Machine Cleaner Tablets are specially formulated to clean all ice makers including countertop, portable, and commercial style machines. These tablets are made from simple ingredients that won't harm metals such as nickel, stainless steel, and aluminum plated components that are inside a regular or self cleaning ice maker. To clean the machine, tablets are dropped into the ice maker's water reservoir, left to dissolve, then the solution is run through the machine using a standard clean cycle. This process flushes out hard water deposits, calcium buildup, and limescale that regularly build up inside the ice machine. The resulting dirty water is then discarded and finally the machine can be used as normal. One package includes 24 cleaning tablets which works out to a 1 year supply of regular cleanings. This way, you can enjoy the clearest and best tasting ice year-round.
