6-4 Chapter 6: Maintenance
Cleaning/Treatment Frequency
New MSR:
Prior to placing in operation, the MSR device should be swiped with the MSR Treatment Card.
Existing MSR:
An existing MSR should be cleaned using an MSR Cleaning Card before treating it with a
MSR Treatment Card. For low use retail establishments, the cleaning and treatment procedures
should be followed at least once per month. In areas of extremely high traffic (in excess of 500
swipes per day) or an operating environment that is high in contaminants, such as found in the
food service industry, a weekly cleaning and treatment should be performed.
