Fix sticky analog thumbsticks on all Sony Dualshock controllers (DS1/DS2/DS3/DS4)
On all the Sony dualshock controllers, the rubber on the thumbsticks is petroleum-based and with time it gets sticky, especially when locked away for years unused. Basically over the years, the compound breaks down and begins to have an oily residue. Rubbing cleaning gasoline (benzin/petrol) will dry them up again and will make them like new!
