Hi all you dishwasher guys with blotches. A funny thing happened to me too. I was busy resurfacing a ball when the phone rang. I had my conversation and a drink. Went back to the machine and turned the bottom side of the ball up,wow! what did I see, a two tone ball. This ball that I was resurfacing was a Ninja with Urathane coverstock.Naturally, I wanted to know more and started experimenting. So on went a polyester ball. I went through the whole process again, up to having a drink. I had another drink, went back to the ball spinner,checked the polyester,and found no two tone.
My conclusion was that polyester is a far denser material than urathane which is very pourous and absorbs just about everything. Keep in mind, that ballspinners generate a lot of heat from the bearing upwards, and evaporates the water which is then absorbed at a faster rate into the ball with a deeper penetration. Also remember that I did not use any detergents, so this could not have any blotching effect.
With this I also remember a time when I was bowling in England, met up with their team coach and had a discussion about the effect of heat on your bowling ball. From him I learnt never to leave my bowling balls in the boot of a car, as it gets like an oven in there and the expansion rate of the synthetic material is greater than the weight block and can seperate the two materials from each other. If this happens and you shake your ball like an advocade pear with a loose pip, you can hear the clonking inside, so if you use your dishwasher, make sure you use very little heat.
Nice conversations,
Thank you.
