@cnn: your solution is almost the shortest (well,you can abbreviate foreach with for ; ). And I prefere this one!

But the OP wants to conform to the styleguides of PBP & Perl Critics, and postfix-loops are disadviced!

If I was in this situation, I would prefere 

_clean_param($_) for @values;

with the routine transforming $_[0] directly, (it's an alias)

UPDATE: or 

_clean_params(@values); # sub takes arr_ref by prototype
