If you encounter ground coffee escaping the chute and getting on the counter, it may mean your coffee is too dry, humidity is too low (static charge), or even that the grinder chute is too clean.

To fix this, try placing a tiny dab of cooking oil on your finger and rubbing it high up inside of the coffee chute. This will allow a fine layer of grounds to coat the walls of the chute.

The added friction of the grounds on the wall of the chute should slow the velocity of the grounds down enough that the overspray stops.

FYI: This whole step happens naturally with oily coffee beans, but takes a little longer than with the vegetable oil trick.
