How do you delete all dynamic variables of a movieclip?

I have the movieclip:
mcGrazer

with quite a few dynamic variables like this:

mcGrazer.var1

mcGrazer.var2

etc.

If I use:

delete mcGrazer;

it doesn't delete the variables.

But if I use:

delete mcGrazer.var1

it deletes that individual variable.

is there a way to destroy all information (variables) of a particular movieclip?

Thanks.
