It is acceptable for use in machines made by Manitowoc and other manufacturers using nickel. In fact, it was the industry’s first nickel-safe product, introduced in collaboration with Manitowoc. Usage rate should be in accordance with the manufacturers instructions or 16 fluid ounces with three gallons of system water. The number one category of problems troubling an ice machine are water-related, and the most frequently is lime scale. As the water is frozen into ice during an ice maker’s cycle, the naturally occurring dissolved minerals in the water, some of which can combine to form lime scale, remain behind in the unfrozen recirculating ice water simply because water tries to freeze in its pure state. As the cycle continues and more water is made into ice, the minerals over concentrate and eventually precipitate as a lime scale deposit. As the scale begins to form, it creates a physical obstruction that results in: plugged distribution holes, restricted water flow and eventually the ice maker will hang-up or jam. Ice harvest is reduced and eventually the machine will shut down, requiring service. This sequence of events can affect both cubers and flakers. Some believe that flakers are free of scale problems since all of the water is made into ice. Not true. Flakers can scale-up as well, jamming the auger and eventually resulting in a broken belt or drive mechanism. Once the machine is scaled up, it must be cleaned, requiring the use of an acid so that the scale can be dissolved. Obviously, the acid must be effective in order to dissolve the scale but it must also be food grade and equipment-safe. THE NU-CALGON 4287-34 NICKEL-SAFE ICE MACHINE CLEANER IS FOR PROFESSIONAL USE AND SHOULD ONLY BE USED IN ACCORDANCE WITH ALL REGULATIONS AND PROPER SERVICE PRACTICES. PLEASE SEE PRODUCT LABEL OR CONTACT NU-CALGON DIRECTLY FOR USE INSTRUCTION. IT IS RECOMMENDED TO UTILIZE THE APPROPRIETE PPE (PERSONAL PROTECTIVE EQUIPMENT) DURING APPLICATION.

I have two ice makers. I had been cleaning them myself with vinegar and water which seemed to do the job, but honestly once I tried this product, I will use it from now on. Super easy and works great!

I have an counter top ice machine (Fridgidaire) for mine to operate in cleaning mode you HOLD the powerr button for 5-6 seconds .. it got a lot of bacteria and dirt out, I’ll update on ice taste soon as I get my ice machine running …SIDE NOTE it did so much better then just water and vinegar

There is no way for me to test this product to see if it worked, so I guess it did. I will give it the benefit of the doubt. Quality control has gone down the toilet everywhere so you get what you get.

What the mfg recommends… must clean every 3 months to prevent mold. If you own an icemaker it is a must- this one works
