Thanks for the help, both ideas will go to use; hot bath and clean n dull in-between. Just for info, this was the response to the question from the Hammer staff.
"For your No Mercy, I recommend soaking the ball in a bucket of hot tap water for 15 minutes and repeating the process for another 1-2 sessions using clean water. There is no need to use soap or detergent, and this process will remove the oil from the ball and will open the pores. Let the ball dry out for a few hours and give it a try. It is a good idea to do this every 50-60 games."
