How to remove marks from MBP cover?

[Kulfon]

Hello community. As soon as I bought my MBP in June 2015 I got a tech21 armor cover for it to protect from scratches and I took it of today to see that there very visible marks on the cover caused by the case. These are not scratches, just marks. Is there anything that I can use to remove them?

Whoa! After reading your post, I was shocked and I took mine off. I'm also using a Tech21 cover with those rubber protectors inside. And yes, the marks were there! But I got rid of them completely within minutes by using a very good microfiber cloth and pure alcohol (Ethanol). I can see rubber particles on the cloth now. But you can remove those marks. Just don't use water, because rubber is hydrophobic.

If you however live in a sandy area, and sand got inside, then it's a different story.

I polished mine too, almost no sign....but I am not puttting the armor case back!
