How to repair/reuse plastic suction cups Plastic suction cups are used in many applications to hold things to hard smooth surfaces like glass, ceramic, laminate, metal, plastic, etc. With time the suction cups loose their holding (suction) strength due to hardening or deterioration. Before trashing and/or spending cash try this if you want a permanent or lasting installation. 1. Place the item in the position you want it to remain installed. Make matching marks to ensure that is were you want the item installed. Mark a dot in the center were the suction cup is to hold. 2. Clean the old suction cup suction face and mating surface thoroughly, ensure there is not grease or contaminants. 3. Apply a thin coat of urethane base all purpose adhesive such as UHU, Liquid Nails, etc. to the suction face and mating surface (do not use cyanoacrilates such as Super Glue or water based glues, they are too hard or too weak for the job). 4. Wait approximately 15-30 seconds for the adhesive dry to touch and press or install the item with suction cups at the desired location using your matching marks as guides. Keep the pressure for a few seconds to ensure good bonding. Once installed wait for at least six hours for the adhesive to completely dry, before loading or applying weight to your item if it is a hanger or shelve. 5. This should do the trick. If you need to disassemble your item in the future you may peel the suction cups gently using a scraper tool.

Suction cup to window does not hold for more than 30 minutes. Any solutions?

That is pretty typical.

If you want to mount it to the window, then make sure the glass surface is completely clean. A generous amount of saliva on the suction cup will keep it up on the glass for a while.

You are better off using the adhesive backed suction cup disks and mount it to your dashboard.

tomtom one 125 easyport mount won't stick

The soft vinyl suction cup has two ears. Behind the ears are two depressions in the mount ring. The vinyl shapes itself into the depressions and forms two tiny gaps when you try to stick it to the windshield.

Place a pencil or other small round object between the ring and the soft vinyl part. Bend the vinyl outward. You may not be able to see the difference, but it should now stick
