After you buy an air hockey table, you need to make sure that you clean it regularly. The tables works by forcing air up through a series of small holes. These holes are in the surface of the table. The air that comes up then lifts the puck so that it slides with ease. If these holes are filled and clogged with dust, dirt, or anything else, the airflow will be impacted. The whole table could stop working. Cleaning it is a cheap and easy way to make sure that it works for a long time without any repairs.
