The fine salt-like crystals clean out every groove of the blade without needing to adjust the grinder's coarseness. They remove oil deposits and prevent grinders from clogging.

Tasteless and odourless, Puly Grinder Crystals will not affect the flavour of your coffee and is fully safe to consume. 

Recommended use:

1 pack (15g) between every 1kg of coffee beans or at the end of the day for busy cafes, as well as every time when switching to a different bean type.
