How to make the sucker stick better


In theory, if you can't choose to use glue, fasteners and magnets, the suction cup can adhere objects to other objects. In fact, many suction cups fail when fixing one thing to another. A little pre-sucking cleaning and a few drops of water will help ensure the success of the suction cup.

Choose the right surface
Even the best suction cups will not stick to certain surfaces because it is impossible to obtain good adhesion without air pockets. Choose clean, flat and completely smooth surfaces, such as windows or mirrors, the front of the dishwasher or the side of a metal filing cabinet. Slight curves and rough finishes (such as those commonly found on car dashboards) make it difficult to obtain long-lasting suction. Porous surfaces (such as metal or plastic grids) also do not work properly.


Clean both surfaces
In many cases, suction cup failure occurs when the suction cup or the surface it grips is not clean enough. Wipe the inside of the suction cup with a clean lint-free cloth, and then perform the same treatment on the target surface. It may only require a small amount of dusting.

Wipe the surface with white vinegar or alcohol, and then clean the inside of the suction cup. This will remove any greasy film that may prevent good suction. Only apply vinegar or alcohol to surfaces that will not be damaged, such as window glass or shower cubicles. If you want to work on a painted surface (such as a wall), first test alcohol or vinegar in an inconspicuous place.


Water Law
Sometimes, a small amount of water will increase a lot of suction. Rinse the entire suction cup with warm tap water. This helps soften the cup and make it more flexible. Shake off excess water and press the cup on the desired surface. Water droplets inside the cup help prevent cavitation that can cause suction cup failure.


Oil-based assistance
A small amount of cooking oil around the lips of the suction cup and even petroleum jelly can help the suction cup adhere to the surface. Apply the selected substance around the cup attached to the lip side of the other surface. Use as little as possible, otherwise the cup may lose suction.


Secret of success
Sometimes press the suction cup from time to time to remove air bubbles. Changes in temperature and humidity will affect the flexibility of the cup and may also cause bubbles to form or the cup to fall onto the surface. For best results, use the suction cup at a temperature above 40 degrees Fahrenheit, otherwise, the suction cup may be too hard to adhere properly.
