RE: Please HELP Permanent Fingerprints atop of my PINK STUDIO 1535
This is an old thread now but this answer might still be useful as many Dell laptops suffer from this.
I recently acquired a 1525 (pink) laptop on which the rubberized coating had broken down, leaving a sticky residue (I've seen many Dell laptops like this).
Anyhow, after much experimentation, I've (literally) hit on a solution: Furniture Polish. I used an aerosol can of furniture polish (the sort that contains beeswax). Spray on, leave for a couple of minutes and then scrape off the coating with an old credit card or similar using a left-right sawing action.
This method does work, but needs lots of "elbow grease". Any discoloration left over can be removed by further applications of polish and a kitchen cleaning pad (light abrasive pad).
