Suction cups are used to hold objects on smooth plain surfaces. It is one of the easy substitutes of glue, magnets, or any other holding objects. You often see them used on the slick surfaces of bathrooms, kitchens, windows, and glass.
Suction cups can be used to easily stick on slippery surfaces where glue or magnets are not suitable. Unlike glue, suction cups can hold up well even after it is removed from the original surface.
But the effectiveness of the suction cup reduces over time. There are some tricks that may increase the lifetime of a dirty or used suction cup. Wanna know how to make suction cups stick again?
There is a little trick to help suction cups be placed and be reused multiple times. But suction cups are so easy to use under normal circumstances that most people ignore the trick to keep suction cups holding long and strong.
The process to make the suction cup hold up objects again needs a relatively strict maintenance regimen.
So, if you want to keep using them, then you need to restore their suction power somehow. Here are some of the most effective ways to re-stick suction cups or make them stick better. Check it out!
How to Make Suction Cups Stick Again: Few Steps to Follow
You need to make sure that you follow the steps that will help make multiple uses of your suction cups.
Step 1: Remove the Suction Cup
The first step is to remove the suction cup that you want to move or reuse for the second time.
You shouldn’t have to pull forcefully on the suction cup. Besides, that could damage the suction cup and the surface it’s on.
Many suction cups have a visible release tab along the edge. Pull up on the release tab. This helps the suction cup peel off the slippery surface by allowing air inside the two surfaces and therefore, breaking the suction.
If it does not have a release tab, gently slide a fingernail or silicone spatula into one edge of the suction cup. This should introduce air and let the suction cup fall off the surface. This is a gentle way of removing the suction cup without damaging it and the glass, ceramic or other slippery surface.
Step 2: Clean the Suction Cup
Next, you need to clean the suction cup that you have just removed. It is better to clean it with a dish soap and warm water. If you want to make sure more grime comes off, you can get pretty good results with a spray away dish detergent. It is scrub-free, so you won’t have to worry about scratches on the suction cup.
Then, dry it with a lint free cloth.
This will help you to remove the debris and dust. Using just your fingers or a soft sponge to help clean it will be plenty.
Keep in mind that you do not want to use anything abrasive to scrape on the suction cups. That will take away its ability to get a hold on things.
Tip: Enhance an old suction cup’s elasticity
For some types of suction cups, like ones made of materials that are heat-resistant, you can boil the suction cup.
Get a pot of water on a rolling boil and place the suction cup in it for 2 minutes. The heat will make the plastic more flexible again.
Step 3: Choosing the Surface
There are a few things you will have to consider when choosing the proper surface to place this clean suction cup.
Suction cups may not be able to adhere to certain surfaces due to air pockets preventing a good bond. That means it can’t be used on textured, porous, and curved surfaces, such as car dashboards as well as plastic and metal gratings. As well, curved places can not hold a suction cup in place. To avoid a non-lasting bond, choose a suitable surface to apply suction cups.
The best surface to stick a cup is completely smooth, flat, and clean. As it turns out, the most suitable surfaces are ones that are made of glass and smooth ceramic. Some other favourites are flat parts of coated stainless steel, acrylic, slippery laminate, and hard plastic.
Want some ideas for where to affix a suction cup? Aside from the windows and mirrors, it will also stick well to most shower stalls and the front panel of a coated stainless steel appliance.
So, choose a clean and smooth surface to stick it to. The air pockets will be effectively removed from the suction cup and that can make them tight enough to hold up the object that you want. Just make sure to check the weight recommendations of the suction cup.
Step 4: Prepping and Cleaning the Surface
You can make sure the suction cups stick better by cleaning surface so that it is free of dirt and clean. Therefore, you would need to clean the surface that you have chosen so that the clean suction cup can take a grip.
Wipe the spot with a damp cloth and clean it with soapy warm water. Any grime or debris can prevent the suction cup from getting a strong hold.
All you need is a damp cloth and a household cleaner like cleaning vinegar. Soapy water will also work just fine.
If you’re using the suction cup in a shower, make sure you’ve removed the mineral deposits or soap scum from the shower walls, which could obstruct proper adhesion. Use a shower wall cleaner.
You may have to do a thorough clean-up by scrubbing it again. Double cleaning will eliminate the last traces of dirt.
Make sure to dry the spot properly before sticking the suction cup to it. If there is too much leftover water, then soap and water stains can develop and the suction cup may not have a good enough grip on the surface and will fall off.
Finally, apply some rubbing alcohol and buff it off with a lint free cloth to make sure the surface is free of grease. This helps prepare the surface for suction.
Note: Before applying alcohol or vinegar, make sure it will not harm the surface. Most shower stalls and windowpanes, for example, can be cleaned with peace of mind. But if you want to use them to clean color treated surfaces, then you could first test your cleaner in an inconspicuous area, just in case.
Step 5: Add a Drop of Water
Boiling a heat-resistant suction cup in water for a couple of minutes will help make the suction cup regain its softness, and then it can create a strong hold again.
Once that is done, you can add a drop of water to the sticking part of the suction cup. Distilled water is preferred, but you can also use tap water.
Then press your cup against the surface to attach it firmly. The water droplet will help remove the air pockets during the sticking action. This makes the bond stronger.
You can also do this once you’ve boiled the heat-resistant suction cup. Get rid of the excess water by shaking it off. A few droplets of water will remain, and it can help push out air pockets while developing the seal. Don’t wait long because if you let it sit for a while, it’s going to dry by exposure to the air. Air drying would leave a mineral residue from the tap water.
Step 6: Add a Small Amount of Oil
Adding a minimal amount of oil or petroleum jelly to the inner lips of the suction cup increases the hold. You can use your finger to rub a little bit of the lubricant onto the suction cup’s rim.
While cooking oil is a safe bet, petroleum jelly can also get the job done.
Be careful of using too much. You’ll want to use only a tiny amount. Overdoing on the lube will make the suction cup lose its suction ability.
Step 7: Remove Air Pockets By Pressing
If you have followed the previous steps to clean and prep the surface and suction cup, then this step is easy.
Place the suction cup onto the desired surface. Press the suction cup firmly in the centre, to make sure that there are no air pockets left in between the suction cup and the surface.
Apply this pressure for 20 seconds to make sure there’s no bubble left. The removal of the air pocket will make the suction cup bond strong and will maintain the strong bond until you uninstall it.
Once you attach the cup, let it sit for a few hours so that the bond has some time to set. During this period, no extra weight should be put on it.
Tip: Occasionally release any trapped air from an installed suction cup
From time to time, it’s good practice to check how well the suction cup is sticking. Indoor air has natural changes in humidity and temperature, and that could change the strength of the suction. You can do this by giving the suction cup a firm push every now and then. This will help release air that may have started to collect over time.
Bonus Tip: Damage-free sticker hooks may be a better solution
If you can’t always check on the suction cups but need a way to hang something semipermanently, there’s a better solution. For example, when you hang a shower caddy, you can’t afford a suction cup giving out. You can use removable sticky hooks that are made for areas with high humidity like the bathroom.
How Do You Get Suction Cups to Stick in the Shower?
Sticking the suction cup in the shower can be tough because of the cold wall. But it is not impossible. You can follow Step 4 to prep the shower wall before attempting to stick a suction cup in the shower.
Then, to prepare to reuse an old suction cup, you can boil the suction cup. The boiling will make it soft and more pliable.
And after you boil it, stick it to the shower area and enjoy the strong hold. Do press it on firmly for about 10-20 seconds so that you remove all the air pockets between the wall and suction cup.
How to Make Suction Cups Stick to Cold Glass?
First, make sure the surface and suction cup is clean by following Step 2 and Step 4. Next, sticking the suction cup will take a tiny amount of oil on cold glass.
Sticking the suction cup after boiling will make it more pliable and renew its suction ability.
Next, let it cool and then shake off the water. Or you can dry it and use a very small amount of oil on the lips of the suction cup. Then, install it on the cold glass.
Why Do Suction Cups Stop Working?
Too much of the air leakage is that makes the suction cup stop working. As the rubber gets shrunk due to the cold or changing humidity, the cup can fall off.
That is why you usually cannot blindly trust a suction cup to hold up things for you.
The suction cup may not be perfect, but you can make it useful by hanging light objects on it. The object should also not be prone to breakage. Even some of the best suction cups need to be reinstalled sometimes.
If you want a better solution for semipermanent hanging on smooth surfaces, you can consider using a damage-free water-resistant adhesive hook.
How Do You Fix Suction Cups That Don’t Stick?
The idea is to keep the seal tight. Clean the surface and suction cup by following Step 2 and Step 4. Then, rub a bit of cooking oil or petroleum jelly on the inner perimeter of the suction cup to enhance suction. You can also wet the inner rims with damp fingers. Adding a bit of moisture can make suction cups stick again by creating a tighter seal.
How to Make Suction Pads Stick?
Place suction pads down on the surface and press firmly. If they don’t stick well, clean the surface with rubbing alcohol and a lint free cloth. This gets rid of unwanted grease. Follow Step 2 for thorough cleaning and preparation of the suction cup. Then, rub a little bit of petroleum jelly or cooking oil around the inner perimeter. This helps them adhere to the surface better. Use a small amount to prevent pads from losing their suction power.
Takeaway
Suction cups are a useful attachment tool. However, they can lose their stickiness over time and make you wish you haven’t bothered with them. That’s why you now have some tips on how to make suction cups stick again.
Suction cups are used to hang different things, from bathroom towels to toothbrush holders. These cups work by compressing air to produce a force strong enough to stick them to all kinds of surfaces, but the material often becomes less sticky with time. For that reason, you might want to know how to make suction cups stick again.
The reuse of suction cups can help you save money and stop the objects from getting ruined by falling.
When you follow the steps accordingly, you can make the cup hold well and strong, up to the mark. Then, you can get the fullest use of the suction cups that you already own.
