Is there an Unformat in MMA 3.0?

In order to simplify input and to maintain some
compatibility with version 2.2 I have used Format
to get nicer output for certain symbols. For example

	Format[la] = Subscript[\[ScriptL],a]
or
	Format[Ph'[x]] = \[Phi]'

But there are situations when I would like to revert
to the original form. I have tried

	FormatValues[la] = .

but this does not seem to work (always) and cannot be done in
the case of the second example.

Is there some way to completely erase formatting 
information about specific symbols and expressions?
