In theory, suction cups offer a great way to attach objects to other objects when glue, fasteners, and magnets are not an option. In reality, many suction cups fail when it comes to keeping one thing close to the other. A small pre-suction cleaning and a few drops of water help ensure the success of the suction cup.
How to Make Suction Cups Stick Better
Choose a suitable surface
Even the best suction cups do not stick to some surfaces because it is impossible to get a good connection that is free of airbags. from a metal filing cabinet. Light curves and textured finishes, such as those commonly found on car panels, hinder the performance of long-lasting suction power. Porous surfaces, such as metal or plastic grilles, don\’t work well either.
Clean both surfaces
In many cases, suction cup failure occurs when the suction cup or surface that is clinging is not as clean as it could be. Clean the inside of the suction cup with a clean lint-free cloth and do the same with the target surface. A light powder can be all they need.
Clean the surface with white vinegar or rubbing alcohol, then do the same with the inside of the suction cup. This removes any oily film that can avoid good suction. Apply only vinegar or alcohol to a surface that won\’t be damaged, such as a window panel or shower booth. If you work with a wall-painted surface, try alcohol or vinegar in a discrete area first.
The water method
Sometimes a little water adds a lot of suction power. Rinse any hot, almost hot and coughing up suction cups. This helps soften the glass, which makes it more flexible. Move away from excess water and press the cup to the desired surface. Water droplets inside the cup help prevent airbags that can cause suction cup failure.
A small amount of cooking oil or even oil jam around the suction cup lip also helps the cup stick to a surface. Apply the chosen substance to the perimeter of the cup on the side of the lip attached to another surface. Use as little as possible, otherwise the cup may lose its suction power.
Tips for success
Press the suction from time to time to remove the airbags. Temperature and humidity changes can affect the flexibility of the cup, which can also cause air pockets to develop or the cup to fall from the surface. For best results, apply the suction cup to temperatures above 40 degrees Fahrenheit, otherwise it can be very difficult to adhere properly.
