Boosters and Tuners etc 
Boosters and tuners also contain VOCs ... so they're banned too.
Your rubber must be used just as it's been authorised by the ITTF.
You're not allowed to change or modify its playing characteristics by using chemical or other treatments, nor change its friction, outlook, colour, structure, surface, etc.
If you want to clean your rubber, you should only use plain water.
