Another weird thing I tried some time ago was ceramic hob cleaner, the standard stuff for kitchen purposes. I wanted a sheen, high grit surface (Abralon 2K and 4K was not invented at that time, and Trizact not to get) on a Particle Plum Pearl Power Groove and get rid of the polish.
It worked very well (to my surprise): I got a matte, really raw surface finish after some rubbing. As a bonus, the ceramic hob cleaner also extracted surface oil from the coverstcok. The ball was SO tacky, I never achieved thjis again with the bucket method or a tour in the oven. Probably because the dry cleaner on the surface completely sucked up ANY oil and bound it very effectively.
The ball read the lane eralier and hooked more, just as planned. I never tried it again afterwards, but it seems to be an option for a fine, sheen finish and a clean coverstock at the same time?
About the sandblaster: I would not do it, unless you have the correct and probablöy very soft grain material at hand. I am afraid that this is too abrasive, and if you are nor careful the ball might get out of spherical shape and catch "bludgeons", not rolling properly anymore?
Th rock tumbler is, as far as I know, a device that is used in bowling ball production to even out the internal life of a ball, e. g. the core with the filler around it before the coverstock is added. With the right abrasive material, this could be worth a try, although I think you will get the same with sandpaper/pads and a simple cross hatch sanding.
