Ice Machine Cleaner 16 fl oz

I have an Igloo brand countertop ice maker that holds about 1/2 gallon of water to make ice. Over the few months that I have had it, I’ve had a hard time keeping it free of hard water build up in the bottom of the water tank. And every time I used it (about once a week) there was always some black mold present that I would clean by hand using typical kitchen cleaning products (409, Dawn dish soap, etc), but it was a lot of work and still wasn’t getting the hard water build up out, no matter how much I scrubbed. So I decided to give this product a try. I don’t have a cleaning feature on my machine, so I put 2 oz of cleaner mixed with 1/2 gallon of water into the tank and ran it to make ice. After the tank was 1/2 empty, I added another 1 oz of cleaner with 4 cups of water and ran it again. When the tank was nearly empty, I filled it with just clean water and ran it again until nearly empty. I poured out the excess water and wiped it dry. I was so pleased that all of the hard water build up was gone! I can only assume that any build up or mold I’m not able to view inside the machine was also cleaned out. I will definitely be making this a part of my cleaning routine. Highly recommend!
