Is your iPhone or any other phone button getting stuck?
Or you press it and you can’t hear the click?
1 Power off your device
2 if you have a case on your device, remove it.
3 wipe the bad button with this:
The alcohol will get inside the button and clean it, removing anything that might be stuck. And since its alcohol it will disapate and evaporate out of the phone or device.
This works for lock, volume and home buttons on the iphone and other devices.
After this your home lock or volume button should work ok.
