1. A dispenser comprising:
- a liquid container for holding a liquid;
a liquid pump for moving the liquid from the first container to a first outlet;
a grit container for holding grit;
an air pump;
a first passageway extending from the air pump to the grit container;
a second passageway extending from the grit container to a second outlet; and
an actuator for actuating the liquid pump and the air pump;
wherein the air pump causes air to flow through the first passageway into the grit container and causes at least some grit to flow through the second passageway and out of the second outlet anda mixing chamber located downstream of the liquid pump and upstream of the first outlet, wherein the mixing chamber receives a liquid from the liquid pump and air from a second air pump and mixes the liquid and air to form a mixture that is dispensed at the first outlet in the form of a foam.
