Cleaning the controller outside?

I don't know how to clean the outside of the PS5 controller on this grip.

Thanks in advance.

With a damp cloth

Is that dirt at all? It looks to me as if they were quirks / scratches, but maybe I'm just deceiving the slightly poorer quality of the photo.

Your photo is very out of focus. When taking photos, make sure there's enough light. It is difficult to see what it is.

1.) Try a damp kitchen roll if it's dirt, a lot of things only go away with water

2.) Try an alcohol solution if there's mold

3.) Run your fingertips and nails over it, maybe it's a very small notch in the paint - there's nothing you can do about it

4.) You can also try vinegar

5.) If all else fails, use soapy water

Yes, the quality of the photo is 😅
