I would love to buy a diamond ball cleaner, as think they look good, do a great job. But for 500 dollars, i don’t know. Now, i just timed myself cleaning my balls with pool ball cleaner/polish, and it took me about 10 minutes. First wipe each ball with a nice amount of polish on a wet micro fiber towel, then with a dry micro fiber towel, clean and polish each ball. They come out very shiny. I do this once a week when i clean and wipe down the table. Table and ball come out great. Oh well, i will keep thinking about it.
