I like the fill of the rubber coating on my phone and GPS. Unfortunately as they get old the become soft and sticky

Is there any way to clean and fix this problem

Try googling "device rubber coating becoming soft and sticky"

" Please note that these fixes are only temporary. Once the plastic starts to degrade, it will continue and the problem will be recurring. It is best to replace these parts whenever possible. "

" Windex or other window cleaner "

" Talc will work on mild cases "

" rubbing alcohol (isopropyl / denatured alcohol) or naphtha usually cleans it up "

Alcohol wipes ?
