1. soak in as hot water as you can get out of the tap, dish soap, and ammonia until water is cool
2. drain and fill again with hot water and some more dish soap...water hot but not so hot you can't touch it (basicly rinsing the ammonia out)
3. Get a 3M Green Pad (from grocery store or hardware)
4. scrub each one carefully and set them aside until dry
5. then use 40 grit sandpaper and carefully scrub the surface bringing up the nap
the soak and green scrub will make them look like new and they will play better but the sandpaper part is needed to bring the nap all the way back...it takes some finesse to get a cut of sandpaper that will wrap around the ball about 3/4 of the way so you can cradle it in there, sort of like hugging it, otherwise you may create flat spots...you will be taking a little of the surface off which will be evident from the pink dust but you will also bring up a good nap with the 40 grit
there are ways to make tumblers which is what the person selling them in Texas did...there are any number of ways to do that most of which use a very coarse sandpaper...tumbling brings up the nap and makes much less dust but it is a major project to make a tumbler and if you only have a few balls its not worth the effort which starts up buying a used dryer...i will post or link you to one or more of these after I look for them...it may be a day or two
just so happens I did 20 of these last week for a friend, which took a couple hours, and am doing 30 more of my own tonight...I have only 11 left to sand paer and its 2:13 AM...man, what a fooser will do...I definately need to get a real life
