The glass on the screen of my MacBook Pro has been stained by a few drops of acid that have damaged it. How can I change the screen?

The simple answer is… you don’t. These machines are horrible to work on, not to mention the slim part availability. You are better off taking your MBP into an Apple Authorized Service Provider or to an Apple Store to have the screen replaced there. Plus, you may be under warranty still.
