God damnit Robyn, quit doing stuff that works, I want to hate everything you do.
Orange peel (the oil) with vinegar is a great degreaser (that will also strip varnish and destroy the skin on your hands). Added benefit: it helps keep flies and gnats away, since the orange oil dissolves exoskeletons.
Eta additional tips: orange peel and baking soda. Mix them together with a couple drops if water, cover, let sit, and you get a great scrubby degreaser for the deep, cakes-on crap that ruins your sponges. Rinse with orange peel vinegar. This will also strip varnish. And use gloves, because it will strip the skin off your hands.
