My family and I have a nicely functioning computer. however, I know that every once in a while I have go in there and clean out the 'stuff' that collects during normal internet usage. We alo have an IPAD which everybody uses to check Email, go on Facebook, and play lots of games. My question: does an Ipad ever need "Cleaning out" and if it does, how do I do it?

About.com has a tutorial on how to clear iPad's internet cache.

If you use something other than Safari as a web browser on your iPad, you'll have to delete the cache for that browser separately.
