Is regularly cleaning your table tennis rubber worth bothering with?

Most people clean their table tennis rubbers but do you clean them after each time you’ve used them or are you one of those people who cleans them only when you can be bothered. If you’re one of the later ones, you could be missing out on a lot of performance your rubber is capable of giving you.

This is a comparison of grip of a sheet of gambler outlaw which has been used for about 4 hours since it was last cleaned and then the same sheet
of outlaw cleaned with a dish cloth and water.
