What to Do When Car Suction Cups Won't Stick?

[KendraAnn]

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.
