What to Do When Car Suction Cups Won't Stick?
2 Answers
Methods to make suction cups more secure are as follows: 1. Use water if the suction cup won't stick: First, clean and dry the wall or mirror surface. Then, drip a few drops of water into the suction cup of the hook and quickly attach it to the wall. Press from the center outward to expel air from the suction cup, making the hook adhere more firmly. 2. Use hot water if the suction cup won't stick: Clean and dry the wall or mirror surface to prevent dust or small particles from allowing air into the suction cup. Soak the suction cup in hot water (70 to 80 degrees Celsius) for 10 to 15 seconds, then attach it to the wall, pressing from the center outward to expel air and ensure a firmer hold. 3. Use soapy water if the suction cup won't stick: Apply soapy water to the inside of the suction cup, quickly attach it to the wall, and wait until it's completely dry before hanging anything.
Oh, I've also encountered the issue of car suction cups not sticking properly, especially when the navigation device suddenly falls off while driving—it's really distracting. When I first started driving, I often made the mistake of thinking it was due to poor suction cup quality, but later I realized it was because the car window surface was too dirty, with too much dust and fingerprints preventing the suction cup from adhering. The solution is to thoroughly clean the car window glass with a damp cloth, especially choosing a smooth and flat spot to place the suction cup, avoiding uneven areas. If the suction cup is too dry, lightly dampen it with water before pressing it on, and hold it tightly for a few seconds to ensure a firm grip. I've also tried using dish soap to wipe the glass, which helps remove grease stains—it works quite well. Aging suction cups are another common factor; just replace them after a year or so—they're only a few dollars. Since adopting this habit, I've never been bothered by navigation devices falling off again, making driving more focused. New drivers should give it a try—it's simple and hassle-free.
