There are a few things you can do to clean hair clippers with alcohol. First, make sure the clippers are completely dry. Next, place the clippers in a bowl or other container filled with water. Pour enough alcohol into the bowl or container to cover the blades of the clippers, and turn on the water. Swish the alcohol around until it’s fully mixed in with the water. Place the bowl or container in a sink and wait for it to cool slightly before using.
