The powerful internal magnets lock the two cleaning sides ( sponge with a rubber squeegee end ) together through the glass so when you move one side, the other side follows.

All you have to do is to slide the magnetic cleaner back and forth to thoroughly clean the glass.

Environmentally friendly: all you need is warm water and plain detergent to clean
