I used wax remover on a set of Aramith Centennial balls and they turned yellow, I went and bought a new set because no matter what I did I could not get the yellow out. I did not try a dish washer, but that is about the only thing I did not try. The yellow seemed to be permanent. I did soak them in boiling soapy water, to no avail.
About a year later I used Aramith cleaner in my mechanical ball polisher for about 30 minutes or more and several iterations of cleaner, maybe a ¼ bottle in all. I was surprised to find that the balls cleaned up.
I conclude that Aramith Ball Cleaner is one heck of a product. It did what nothing else could do. I do not think it makes any difference what ball cleaning machine you use the machine simply rotates the balls many more times than you can do by hand. When this is combined with Aramith you get the best job.
