Moisten the inner rim of the suction. A bit of water on your finger is the most common way. Please remember not to moisten the rim too much! Just enough to coat the surface of the rim - if the suction cups slide after pressing down, you have used too much water Press the centre of each suction cup all the way down firmly to the glass and keep firm pressure for about 15 seconds. Then gently release the pressure until all the air bubbles inside are released, to firmly seal the cups to the surface.

To improve suction and help keep the seal tight, dampen your fingertip with water and lightly moisten the inner rim of the suction cup. This helps create a tighter seal. The key is to not get too much moisture… just barely enough to coat the surface.
