As pzbagel stated you can use the the delete_all method to clear the CGI object's params using the OO interface. You can also use the functional interface, like you do in your example, to delete the params by using the Delete_all() function (note the leading cap).

If you want to overide the "sticky" behavior on a per-field basis use -override.

print textfield(-name=>'name',
                -default=>'',
                -override=>1
                );
