# Maintenance

{% hint style="warning" %}
To avoid damaging the read head, only clean the card path with approved cleaning cards. DO NOT use liquid cleaning products or insert any other objects into the device.
{% endhint %}

Periodic cleaning of iDynamo’s exterior may be required. To clean the outside of iDynamo, wipe it down with a soft, damp, lint-free cloth and then wipe it dry.

MagTek’s double-sided cleaning card *96700004* is designed to clean the magnetic read head in the MSR swipe path. Keeping the head clean is essential to the device’s functioning. MagTek recommends swiping a cleaning card once per week to avoid card misreads.
