On the pulse rate monitor strap it is written that it should be cleaned every 7th training day. It would be nice if the garmin app could keep track of this and remind me to clean the strap.
I always clean the strap every Wednesday even if I often do more than 7 activities per week. Put an appointment in your calendar.
Every 7th is just a general advice that will work for most people. If you are doing really long activities and you are sweating a lot you should probably clean the strap more often than every 7th activity. If you are doing really short activities with little sweating you can probably clean it more seldom.
