Hi, i need some help. Can you guys guide me how to clean this surface?
I tried glass cleaner / IPA and none of them are working.
I tend to use denatured alcohol (shellac thinner) for everything like that.
After i use thinner, the result is the same.
I didn't mean paint thinner. That will leave a residue and may damage the plastic.
Even if i use thinner, it is still the same and the plastic did not damage
