Instead of waiting for the build-up to get so overwhelming that eventually the appliance just needs to be thrown away and I need to buy a new one---what a pain! I found an amazing way to clean the gunk off, and this is very easy and inexpensive!
Create a mixture of baking soda and hydrogen peroxide until it forms a paste. Rub it onto the appliance with your fingers and use a paper towel to wipe it off. Leave it on for a little while if there are a lot of trouble spots.
