That drilling is basically a skid/snap drilling, to get the ball down the lane with a strong backend reaction. As for soaking it, just put it in hot water (sink, bucket, bath tub) with some dish soap, just as long as the water is not too hot for you hand, its ok for the ball. I leave mine in for half an hour, take it out, wipe it down with a towel and simple green (or any house hold cleaner) and put new, hot water back in the tub, and do another half an hour, and clean it again, then let it dry.
