Rinse the Suction Cup in Warm Water

We love a good home improvement hack, and this is one of our favorites. If you’re having trouble making suction cups stick, try submerging your suction cup in hot water. Because the heat softens the material, this is an effective trick.

To get started, you’ll just need to boil a pot of water. Once the water starts boiling, remove it from the stovetop and turn it off. Then, toss in your suction cups for half a minute. Once they’ve been completely submerged for 30 seconds, use a pair of tongs to take them out of the water. Dry them with a towel without lint and voila! You have suction cups that will adhere easier. For the best results in making suction cups stick, adhere immediately after drying them.

Get Creative with Petroleum Jelly

If you have petroleum jelly lying around your house, you have what it takes to make this home hack happen. All you have to do is dab a little petroleum jelly into the cup and hold it in place wherever you’re attempting to stick it. Yup—it really is that simple.

You might be wondering why petroleum jelly is so effective in making suction cups stick. Because the jelly makes a seal between the wall (or tile) and the cup itself, the suction cup is able to seamlessly grip the wall. Remember: for this hack, less is definitely more. Too much petroleum jelly can actually work in reverse. (And if you don’t have petroleum jelly in your medicine cabinet, cooking oil will suffice.)

Inspect and Clean the Area Where You Want to Adhere the Suction Cup

In some cases, the suction cup isn’t to blame for the struggles you’re facing. In fact, it could be the surface itself that’s causing the trouble. Make sure the area is clean, dry, smooth and flat. If your surface isn’t, you might experience more trouble making suction cups stick.
