There are two main reasons that Doorhickeys fall off:

1. The non-porous surface, such as glass, isn't clean.

2. The Doorhickey handle hasn't been turned enough revolutions to create a strong suction.

When properly installed, The Doorhickey should remain suctioned to your glass for a long time!

Soak The Doorhickey in warm water, then try turning the handle and suction cup in opposite directions.

Follow these easy instructions to install The Doorhickey on glass and other non-porous surfaces.

Simply turn the Doorhickey handle counter-clockwise several revolutions until you can use your fingertip to easily remove the suction cup from the glass.
