What is the best way to clean the PS4 controller of grease?
With disinfectant and kitchen paper e.g.
Other strong alcohol / ethanol containing agents, "brake cleaner", "benzine" and the like would also work.
When you don't have any of it?
Can't tell you everything that comes into question on command.
In an emergency, just put a rag in the water and some washing-up liquid. Then squeeze it out very well so that it is only damp and then wipe the controller thoroughly with it. Repeat if necessary. But be very careful that the cloth is really only damp. You shouldn't bring water into the controller.
Something like glass cleaner or glasses cleaning cloths could also work.
