A quick scrub with WARM soapy water should clean your balls just fine! ;-)
Because heat makes plastic expand in hot water.
ping pong ball
This is a method to repair a dented ping pong ball.
The hot water will soften the ping pong ball, causing it to regain its original shape as the material becomes more pliable. The dent should eventually pop back out as the ball absorbs the heat and expands.

The heat from the boiling water warms up the air inside the ping pong causing the air to expand and push the dent of the ping pong back out.
The inside of a ping pong ball is empty, and the skin is made of celluloid. A common problem is that the ball is easily dinted. To remove a dint in the ball's surface, place the ball in hot water. The air inside expands on heating and pushes the dint out.
Yes. The hot water will make the air inside the ball expand, removing the dent.
the heat makes the air expand inside the ball, which in turn would make it "blow up" back to its original shape
The heat softens the ball and, unless the ball is cracked, the pressure increase from the air inside the ball being heated causes a small dent to pop out.
A dint in the surface of a pingpong ball can be removed by putting the ball in hot water. The hot water will expand the air inside the ball and push the dint out, restoring the original shape of the ball.As to a hole? A hole would allow the pingpong ball to fill with water.
The air inside expands when heated, and increases the interior pressure. Unless a ball is so badly crushed that it cannot become round again, the dented part will be pushed out to create its original shape.
