Oven cleaner is lye, it tends to yellow, burn, or melt plastics and hulls.
Cleaners like Simple Green work
well. Liquid Tide detergent works well. And if the crud is embedded dirt, SoftScrub works well. A paste of BonAmi or other cleansers will work
too, use a ScotchBrite pad with any of them.
Acetone is going to soften (attack) the plastic and make if gummy. That's risky for most of us.
