We purchased a used grinder for our cafe opening next month and the inside of the hopper and the dosing chamber are heavily stained with rancid coffee oils. Can anyone give me some advice on how best to clean the hopper and dosing chamber insides effectively without damaging the plastic? Simply soap, hot water & elbow grease? Rubbing alcohol? Or is there something tailor made for this type of cleaning job? Thanks for your help! - Cash c[_]
