There have been a few questions about how to clean your iPad. Please see the link below for directions on cleaning.
To clean iPad, unplug all cables and turn off iPad (press and hold the Sleep/Wake button, and then slide the onscreen slider). Use a soft, slightly damp, lint-free cloth. Avoid getting moisture in openings. Don't use window cleaners, household cleaners, aerosol sprays, solvents, alcohol, ammonia, or abrasives to clean iPad. iPad has an oleophobic coating on the screen; simply wipe iPad's screen with a soft, lint-free cloth to remove oil left by your hands. The ability of this coating to repel oil will diminish over time with normal usage, and rubbing the screen with an abrasive material will further diminish its effect and may scratch your screen.
If you are a student with a case, see this link below. If you take the iPad out of the case take extra care when putting it back together.
The best way to clean Survivor is to use a clean, lint free cloth with warm water. Do not use anything caustic such as alcohol or other cleaners, as this can damage the case. Just make sure to let the case completely air dry before putting your device back into the Survivor case.
