ELI5: Why wax occurs in our ear canals and should ears be cleaned?

My dad has an ear wax problem at the moment from to much wax.  The doctor says he needs to regularly clean his ears but many people say not to. I am confused.

They say not to only because a lot of people don't do it right.  There are specific ways you're supposed to do it, as well as specific tools.  If you have a mild wax problem, like just a little buildup around the canal, a q-tip is fine if used safely.  If you have a bad problem, all a q-tip is doing is packing it back further into the ear canal.  They actually make soft little ear "scoops" exactly for this.  There are also ear cleaning fluids; you pour a couple of drops in, let it sit, then tilt your head with a tissue under your ear, and all the wax pours out.  

He really should ask his doctor what he thinks the best method for cleaning is.
