Using the Gelish Mini Touch LED Light is a breeze. First, plug in the USB cable to a power source. Place your finger with the gel nail polish inside the light. The touch - activated feature means you just tap it to start the 30 - second curing process. When you're done, simply remove your finger. As for maintenance, keep the light clean by wiping it with a soft, dry cloth. Avoid using harsh chemicals as the light has an acetone - resistant finish, but still, it's best to be gentle. Store it in a cool, dry place when not in use. Also, make sure to handle it with care because of its portable size, it can be dropped easily. The anti - slip grip is there to help you hold it steady, so take advantage of that.
