To clean a card reader, you can use a soft, lint-free wipes and a small amount of isopropyl alcohol (also known as lint-free IPA cleaning wipes).
Here are the steps to follow:
- Power off the device that has the card reader.
- Dip the cloth into the isopropyl alcohol and wring it out so that it is damp, but not dripping.
- Use the cloth to gently wipe the surface of the card reader, being careful not to apply too much pressure or get any liquid inside the reader.
- If there is any debris or dirt that is stuck to the card reader, you can use a toothbrush or other soft-bristled brush to loosen it before wiping it away with the cloth.
- Allow the card reader to dry completely before using it again. This should only take a few minutes.
It’s important to avoid using water or other liquids that could damage the card reader, as well as any abrasive materials that could scratch the surface.
