It should work also.
Just search for the specific Freq., (using a parametric EQ) that is the problem by Boosting the bands, and then search through untill you hit it ( you'll hear the problem stand out ).
Then go to your notch and cut that specific freq.
Another usefull trick is to use a De esser. Do you have one?
