Don’t you hate how sometimes some suction cups just don’t stick the way you’d like? Well, here is the tricks MomsBudget uses to make sure those suction cups stick, and stick good!
Do note that glass is the best surface for sticking suction cups, although some walls or other flat surfaces (ie. a flat stainless steel refrigerator) can also successfully hold suction cups.
First, make sure the suface you are sticking the suction cup on is completely clean. If there is dirt or grit, the suction won’t be able to “suck” to hold on. So wipe down the surface first. And yes, even grease and fingerprints can mean a less-than-stellar surface to stick to, so you can wupe down any oils that may be on the surface by using rubbing alcohol.
Then, when you go to stick the suction cup, get the inside of the suction cup slightly moist right before you suction it onto the wall or glass, as this will help it keep its suck.
