You could spend 30 minutes placating your erupting mama by scrubbing out the microwave with dish soap and steel wool after you accidentally think it takes 5 minutes to melt butter, and reheat her homemade marinara sauce without a cover. Orrrr, you could gift your mama this Eruption Disruption Volcano, a microwave cleaner that steams away the crud inside your nuke box using a simple mixture of vinegar and water.
The Eruption Disruption smokes and gurgles for a 7-minute stint in the microwave chamber. The vinegar-laced steam softens dirt and caky stains during this time, making it easy to wipe them away with a sponge when the cycle finishes. Well, supposedly. I haven't tried using a volcano to clean my own microwave, but those who have seem generally satisfied with its stain-removing (and lava-free!) powers. My guess is that if you're a dude who's tried to hard boil eggs and let multiple burritos explode and countless slices of bacon pop all over your microwave for the 3 years you've lived in your place, and the Eruption Disruption is your first attempt to de-gunkify it, you'll need the grease in your elbows to erupt a little too.
Eruption Disruption volcano microwave cleaners come in 4 different colors.
