The only solution is to remove the coating.  91% isopropyl alcohol should work without damaging the plastic underneath, but it will take some effort.  There are other substances that work as well. The same issue has plagued Eton/Grundig radios for years and the solution is the same: [URL] The other option is to replace the affected parts completely, but replacements are likely of similar age and condition.  
Hello,  I recently got my first Alienware laptop M17x R3, albeit a bit old, it runs fine. My issue is with the tacky rubberized coating on the palm-rest, the lid isn’t too bad yet. I am looking for general suggestions to combat the issue, as it is kind of annoying and having pets in the house isn’t helping the issue any. Thank you!
