How do I get my suction cups (for my radar detector) in my car to stick to the windshield?

Question

I wet my finger and use it to make the suction cups moist, but it just isnt working anymore. The radar detector keeps falling off the windshield. How do I get it to stick without using glue?

Answer 1

wash the suction cup with soapy warm water and don't dry it just stick it back on it should grab hold

Answer 2

it sounds like the windshield may need to be cleaned using windex or any other high quality glass cleaner. This is especially true if you smoke.... or there is a lot of temperature change during the day where you reside. Sometimes the rubber just wears out, in that case, you may be able to find replacement cups at a Dollar Store, hardware store or autoparts center. Hope this helps.

Answer 3

Clean the inside of the window with a high quality glass cleaner. If there is any type of contaminant on the glass, the cups won't stick. If it still falls off, replace the defective suction cups.

Answer 4
