I'm not sure why some get the less desireable results with it. Maybe too strong/too weak a mixture? Maybe not giving it enough time to break down the oil? Maybe the slippery "residue" is oil coming from the cover? Have you ever rested your hand on the ball and brought oil back up to the surface?
If the minimal heat from my hand can bring the oil up, then why couldn't creating friction (heat) by wiping the cover with a towel bring oil to the surface? Could this be the residue that people are feeling? I don't know, I'm just thinking out loud here.
I have used it for years because it gets the surface tacky clean. If it will break down motor oil from my driveway, it should be strong enough to break down a little lane oil from the surface of a ball if given time. I don't profess to be an expert, just know that it has worked for me and have had reps from 2 different ball companies endorse it's use. And no, these reps will not be identified, because they were speaking "off the record" because their employer also sells bowling ball cleaner.
Each of us may experience different results, but if it works well for you then don't be afraid to use it. If your results are less than stellar then by all means feel free to buy whatever works for you.
