Here you go with an official statement:
http://morichbowling.com/Products/Cleaning.htmI for myself do as follows.
cover the thumbhole so that the tapes don't get wet (I use different brands and some tend to loose thier adhesion and fall out when they get wet... that is all! Water won't hurt the ball)
I put the ball in the sink or a bucket big enough and cover it with water.
Warm water.. not hot so that the condition is not too harsh
For cleaner I use normal dish detergent or simple hand-soap I put in the water when filling the sink/bucket.
Wait 20-30 min (not longer please... the ball will soak up water or stuff... I don't know the real science behind it but from my knowledge and experience it changes color and I guess that is water soaked into the coverstock of the ball)
after 20 min take the ball out/ let the water down the drain and clean it again with flowing warm water... wipe the ball with a clean towel...
Let it dry long enough ( esspecially the fingerholes then when you use grips will hold water... and spilling water on a bowling alley.. approach or lanes itself isn't that good
)
Here's a picture of my Carbide+ with two different times..
left was 20 minutse... right side of the ball was in the water more than an hour:
