round toilet brush
I bought a round toilet brush at Walmart that will just fit through the opening of my ISE/Kenmore with stainless chamber. A little Comet on the brush, stick it in and scrub around. When I pull the brush out it reverses the rubber baffle and scrubs it too. I sometimes still take a paper towel with comet and reach up under the "rim" so to speak and scrub it by hand (far away from the grinder). Usually a gallon of hot water with bleach in it poured down while running is all I need. Mother's old Kenmore was rusted like that inside and it also stank. Replaced it with a stainless chambered one and no troubles since.
