Greasy takeout containers are a pain—oil clings and regular washing barely touches it. Hot water and decent scrubbing power are key. Firmer bristles help break up the film without too much elbow grease. This dish scrub brush I use handles greasy plastic really well—the bristles agitate the oil and soap combo fast. I run hot water, add dish soap directly to the brush, and scrub in circles. Most containers come clean in under a minute. It’s sturdy enough that it doesn’t lose effectiveness after repeated use. Way better than wasting sponges on that kind of mess.
