When you switch to a lower calorie lifestyle, invariably you end up cooking differently. No doubt non-stick skillets and grill pans figure prominently as well as enamel coated cookware like Le Creuset). Cleaning these pans can be very difficult as things tend to stick the less fat you use in cooking.
To make clean up easy, use your old nail brushes; baby nail brushes work best. The bristles are soft enough that you will not damage your pans but strong enough to clean any debris.
Nail brushes work especially well for getting into the grooves of grill pans!
