How to clean and store the Sensor, strap and heart rate vest
This article explains how to clean and store the Firstbeat Sports Sensor, the textile strap and the Heart Rate Vest so that they last longer and measure reliably.
Before you start
- Never put the Sensor in a washing machine or a dryer. Do not clean the Sensor with alcohol, abrasive materials such as wool, or cleaning chemicals.
- Do not store the Sensor wet, in direct sunlight or in non-breathable material such as a sports bag or a plastic bag. Non-breathable material can cause oxidation.
- Straps are consumables. Replace a strap after about 6 months of daily use, at the latest after 2 years.
After every use
- Detach the Sensor. Remove the Sensor from the textile strap. If the athlete uses the Heart Rate Vest, the Sensor can stay in the vest between sessions.
- Clean the Sensor. Dry the Sensor with a towel. If the Sensor is dirty, clean the Sensor with a mild solution of soap and water and dry the Sensor again.
- Rinse the strap. Rinse the strap with cold water and hang the strap to dry.
- Store. Store the Sensor and the strap in a cool, dry place.
Wash the strap every week
Salt and sweat build-up makes a strap that is not washed regularly less effective.
- Check the washing symbols. Check the washing symbols on the strap and on the Firstbeat Sports washing bag.

- Machine wash. Put the strap in the washing bag and machine wash the strap at 30 °C (86 °F) without detergent. Do not put the strap in a dryer.
- Dry. Hang the strap to drip dry without forming creases.
If machine washing is not possible, wash the strap by hand with a mild solution of soap and water at least every fifth use, and hang the strap to dry.
Wash the Heart Rate Vest after every session
- Remove the Sensor. Always take the Sensor out of the vest before washing.
- Machine wash. Wash the vest at 30 °C (86 °F) with similar colors. Do not soak, spin-dry, iron, dry clean or bleach the vest, and do not use fabric softener.
- Dry. Hang the vest to dry. Do not bend the electrode areas of the vest.
Result
The Sensor, strap and Heart Rate Vest are clean, dry and ready for the next session.
