Suction cups are handy devices that can be used to stick objects to smooth, non-porous surfaces such as metal or glass. They are made of highly flexible synthetic materials such as PVC plastic or neoprene and work by creating a vacuum that seals the cup tightly to the surface. Over time, the plastic suction cups may lose their ability to stick due to dirt, dust, or leaks in the cup's seal. To rejuvenate plastic suction cups, you can try cleaning them with soap and water, using a semi-permanent adhesive, or applying a small amount of oil to the cup to improve the seal.

What You'll Learn
Clean with soap and water
To rejuvenate plastic suction cups with soap and water, start by cleaning the suction cup with warm, soapy water. You can wet a soft lint-free cloth with warm water and add a small amount of dish soap. Scrub the suction cup with the cloth to remove any dust, dirt, oils, or gunk from the surface. Be sure to clean both the inside and outside of the cup. If there is any stuck-on residue, try scrubbing the suction cup with vinegar.
After scrubbing the suction cup, rinse it under warm water to remove any remaining soap or vinegar. It is important to ensure that the suction cup is thoroughly cleaned to remove any dirt or grease that could interfere with the vacuum seal.
Once the suction cup is cleaned, dry it completely before moving on to the next step. You can pat the suction cup dry with a lint-free cloth or towel. It is important to remove as much moisture as possible to prevent water droplets from interfering with the vacuum seal.
If your suction cup is still not sticking after cleaning and drying, you can try boiling the suction cup in water for a short time, usually 30 seconds to a few minutes. The heat from the boiling water will soften the plastic, making it easier for the suction cup to adhere to the surface. After boiling, remove the suction cup from the water and pat it dry with a lint-free cloth.
It is important to note that boiling may not be suitable for all plastic suction cups, especially thin, molded plastic pieces, as they may lose their shape when exposed to heat. If you are concerned about the effects of boiling water, you can try soaking the suction cup in unheated water for a day or two instead.

Apply a thin layer of oil
If your plastic suction cup is losing its suction power, one way to rejuvenate it is by applying a thin layer of oil. This method works because oil does not evaporate as quickly as water and forms a better seal.
There are a variety of oils that can be used for this purpose. In the kitchen, edible oils such as olive or coconut oil can be used. Alternatively, you can use nose oil, which can be found on your skin at the edge of your nose. Simply rub your nose with your finger, and then rub the suction cup with the same finger.
It is important to note that oil might degrade the suction cup if it is made of rubber rather than PVC. Therefore, it is recommended to test the oil on a small area of the suction cup first to ensure it does not cause any damage.
To apply the oil, use a Q-tip or cotton wool bud to apply a thin coating of oil around the edge of the suction cup. This will help to close the pores and create a better seal. You can also use petroleum jelly, which will help with adhesion and can be easily washed off walls.

Use petroleum jelly
If your plastic suction cups are not sticking, you can use petroleum jelly to rejuvenate them. This is a simple and inexpensive solution that can be applied to the inside or underside of the suction cup.
First, ensure the surface you are applying the suction cup to is clean, flat, and completely smooth. A window or mirror, the front of a dishwasher, or the side of a metal file cabinet are all good options. Surfaces with slight curves or textured finishes, such as car dashboards, are not ideal as they make it difficult to achieve lasting suction.
Next, clean the suction cup and the surface with a lint-free cloth. You can also use white vinegar or rubbing alcohol to wipe them down and remove any lint or grease. Make sure both the cup and the surface are completely dry.
Now, grab a paper towel or your fingertip, dab a small amount of petroleum jelly, and apply a thin layer around the rim of the suction cup. The layer of jelly should be barely visible. This will help fill in any microscopic gaps, creating a tighter seal.
Finally, press the suction cup firmly and evenly against the surface, expelling as much air as possible. The oil in the petroleum jelly will help create a more robust vacuum, ensuring a stronger, longer-lasting hold.

Seal with clear silicone
If your plastic suction cups are no longer sticking, sealing them with clear silicone can help rejuvenate them. Silicone dries onto the surface and creates a water-tight seal. It works best on surfaces like glass, hard plastic, and tiles.
To apply the silicone, start by getting a small tube of waterproof silicone from your local hardware store. Apply the silicone to the bottom of the suction cup in a spiral pattern, leaving a little free space around the edge of the cup to prevent it from squeezing out.
Once you've applied the silicone, hold the suction cup over the desired surface and push down firmly with your thumb to create a tight seal. Make sure to avoid pushing against the edges, as this can let air underneath and weaken the hold.
If you're using suction cups in the shower or on windows, look for UV-resistant silicone cups to prevent sun exposure from damaging the seal. Additionally, avoid hanging items that swing, as static weight is safer and helps maintain the seal.
Regularly check the adhesion of your suction cups by gently tugging on them weekly. Reinstall them every three months by removing, cleaning, and reapplying to prevent permanent marks on the surface.

Warm the surface with a hair dryer
Warming the surface with a hair dryer is an effective way to improve the suction of plastic cups. This method is particularly useful when applying suction cups in cold environments, as lower temperatures can cause air pockets to form inside the seal, weakening the cup's bond with the surface.
To begin, set your hair dryer to a low heat setting. You don't want to expose the surface to excessive heat, as this could damage it. Hold the hair dryer several inches away from the surface and move it back and forth to evenly distribute the warm air. Continue this process for a few minutes, ensuring that the surface reaches a slightly warmer temperature.
If you don't have access to a hair dryer, there are alternative methods to warm the surface. One option is to use a hot pack or a heating pad and place it on the surface for a few minutes. Another approach is to use a warm, damp cloth and gently press it against the surface. These methods may take a little longer, but they can effectively warm the surface and improve the suction of the plastic cups.
It is important to ensure that the surface is clean and dry before applying the suction cups. Any residue or dirt on the surface can hinder the suction and reduce the effectiveness of the cups. Use a microfiber cloth to wipe down the surface, removing any dust or visible residue. For stubborn grease or grime, apply a small amount of rubbing alcohol or a mixture of vinegar and water. This will help dissolve the grease and prepare the surface for the suction cups.
By warming the surface and ensuring it is clean, you create the ideal conditions for the plastic suction cups to adhere strongly. This simple trick can significantly improve the performance of your suction cups, especially in colder environments.
