One thing everyone tends to forget is the simple fact of physics. If the material is porous and capable of soaking up lane oil, it is also capable of soaking up water or cleaning solution.
A friend of mine had two of his balls stolen. The culprit got scared and threw them in a small pond close by his house. A few days later they were recovered, but we NEVER got them to look right again. and the sonic would hook almost twice as much as before. Wierd, but true.
P.S. If you have any doubt that the ball will soak up water, put the ball in a wet spot and leave it for a day or two. It will be discolored in the area it was sitting on the moisture.
