Artificial colors. Plastics. Chemical dyes. They're in our kitchen. Not in the pantry, but over our sink. Like that neon yellow sponge with the bright green scrub side. We have a feeling that's not exactly natural. Unlike our sponge that shows its true colors: unbleached, undyed white cellulose and tan, scrubby loofah. And its biodegradable, just like the food it cleans up after.
