If you're using IBK Stacking in cleaning the screen, You won't find a huge difference between it and my tool other than that it's much more lighter in the script and giving better result in the most cases.

I used some functions and very light filters to get the same result of IBK color Stacking (Maybe better) with much less effort and also much faster script.

• Just select the screen color and adjust the values based on your shot (Just like IBK Color)
• Enjoy the magic of cleaning by playing with the clean parameter.
  
  
  
  
• V1.1 Update : Now You Can use a new method for creating the clean plate which is picking the color ;)
  Just Select Pick color from the method, Pick your screen color, Click on Picking Done and enjoy the magic again.
• V1.2 Update : Added new Slider 'Erode' For more Control,
                         Now working on all Nuke & NukeX versions.

All that happens without any stacking or any heavy filter so your script will never be heavy or slow.

I hope it helps and waiting for your feedback.
