mine go thru the dish washer- you can take them off and soak in a degreasing solution until they are clean.
I put mine in the dishwasher. You can soak it in the sink with hot water and and a few squirts of Dawn dish liquid.
Put it in your dishwasher
i find using the "Blue Dawn" and very hot water, soak in kitchen sink, rinse repeat if necessary, both sides. Let dry.
I use Dollar Tree Awesome Orange in the half gallon and very hot water from the faucet. Just dip it in and out, then rinse it.
