WARNING

Wear protective gloves and safety goggles when handling ice machine sanitizer.

Ice machine sanitizer disinfects and removes algae and slime. Sanitizer must be used a minimum of once every six months.

Use of an approved filtration system with a polyphosphate scale inhibitor is highly recommended for all ice machine installations and will significantly reduce the need to descale in hard water applications.

For Descaling of Manitowoc ice machines please see separate detailed de-scaling and sanitization process.
