I had good success using isopropyl alcohol as a solvent and a drill with a plastic brush attachment, using less than 300 rpm.

Some choice stickers (McMurdo Station and South Pole Station stickers) have inhabited 3 of my laptops already.

Same (French polar institute and Kerguelen in my case) and I use double-sided tape to place them so I can remove them in the future.

A real McMurdo sticker does seem incredibly cool!

The funny thing is I'm at McMurdo now but they don't seem to have any at the store at the moment

Are those heat insulating by chance?

I never put on stickers (except the Stain Javelin) on my laptop. It may be just me, but if feels messy to me.

There's a big difference between the materials that's used for the sticker itself (paper, plastic) and the glue they used. By now I have a good feeling about the "removability" of a sticker once i have it in my hand.

I sandwich them between my phone and a clear case now. Don't even have to take the stickum protector part off, so when you get a new phone, you can take your favorite stickers easily. Disadvantage: you get like 2 stickers total.

I buy a hard case, then put the stickers on that. Then I can pop it off if I need to be in a more "professional" environment or if I want to upgrade/sell it.

For me it was having to replace my MacBook's screen and loosing all the stickers in the process that made me realize I would loose any sticker used on a Laptop eventually.

did you manage to clean it up? Sometimes stickers leave permanent discoloration of the case, especially on aluminium Macbooks
