A typical question from a university. It should of course be possible to
strip adsorbed proteins in the same way as one uses in experimental
context, i.e. SDS in an acidic glycine-buffer, 1 M or so. But the costs
of the chemicals involved, and even more of the labour required, is much
higher than that of new plates. 

You are supposed to prepare students for a productive life, so don't
give a bad example.
