I've been using a mixture of 40% simple green, 40% isopropyl alcohol (the 99% type), and 20% water for a couple of years now. This has worked very well for me. Just recently, based on comments here on BallReviews, I ordered a couple of bottles of Remedy Rx, and I have to say that not only does it do a better job of cleaning (about the same as Clean and Dull), but more importantly it also leaves the ball with a very long lasting tacky feeling. Even at the end of a 3 game set, only wiping the ball off with a microfiber towel, the ball still feels tacky. Great stuff. I'm going to keep using the Remedy, with an occassional deep cleaning with Clean and Dull.
