How to clean and maintain a coffee grinder

  1. Grind out retained coffee

    Grind out retained coffee between blades.
    NB: Before cleaning read manufacturers instructions!
    Close the hopper chute by pushing the slide gate inwards. Grind out the retained coffee from the grinding chamber into a cup.
    NOTE: Avoid keeping excess coffee beans sitting in the hopper as the coffee will oxidize faster and absorb odors. Only place enough coffee beans that you need each time to make your coffee. When grinder is not in use, keep the coffee hopper and grinder chamber empty and remove lid. This will decrease the rate of the rancid odors developing in the plastic coffee bean hopper and grinding chamber.

  2. Remove hopper

This warns the user Not to connect the grinder to the power source during this cleaning stage. The other symbol is a common graphic yellow caution symbol. Which is typically a yellow tringle with a black exclamation mark that immeadiately says warning to the user.
    CAUTION: Turn grinder off and remove electrical plug from the power source. Gently wiggle hopper and remove.

The other symbol is a common graphic yellow caution symbol. Which is typically a yellow tringle with a black exclamation mark that immeadiately says warning to the user.
    Pull coffee gate outwards and allow the beans to fall into an airtight container.

  4. Use Grinder clean pellets

    Pouring grinder clean pellets into bean hopper to clean your coffee grinder blades.
    Pour a heaped tablespoonful of Grinder Clean pellets into bean hopper and grind through. These pellets are food grade and assist in displacing the ground coffee residue between the blades and help absorb any rancid odors. NOTE: Grinder clean pellets must be used at least once a month from when you purchased your grinder. If your grinder has never been cleaned we recommend to book it into our service center and have a technician clean it thoroughly as the pellets may not be as effective in removing heavy residue buildup.
