mine are treated about once every 2 months to a cleaning.... on average.
I have 4 pearl Uraniums that get cleaned more often, but on average my typical Lane #1 ball is 6 plus years old.... Emerald, and Pearl Uraniums are always in the bag. then I switch out when I want to try something different.
I would say with the possible exception of USA made brunswick coverstock stuff most other 6 yr old equipment is either a spare ball or a lawn ornament.
