A little trick to prevent suction cup hooks from falling off:
1.Toothpaste Squeeze some toothpaste onto the suction cup of the hook and spread it evenly, then stick it onto the painted wooden door and let it sit for half an hour. This is because toothpaste can fill the air inside the suction cup with solids, making the suction cup hook adhere more firmly to the wall.
2.Egg white Apply a small amount of egg white to the inner side of the hook's suction cup. Then quickly stick it on the wall and wait for it to dry before using it. At this time, the suction power of the suction cup hook will be improved by one level compared to before, even if it is used to hang something over ten kilograms, it will not fall off easily.
