Clean and Tacky is better than any other cleaner out there, stronger at least and designed specifically for bowling balls. If it doesn't work, then there's somehting wrong with the bowling ball or your method of cleaning.
The ball will still absorb oil and its performance will still decrease over time, depending on the amount of oil on which you bowl, how rough the ball surface is and how much you rev the ball. It's up to you to keep an eye on its performance: amount of hook, hitting power, etc. When it decreases to a certain point, the ball must be treated to restore its performance. And you have to recognize when the performance decrease is due to too little oil on the lanes and not the ball's oil absorption.
If all of a sudden the ball seems dead, you haven't been watching ...
