A $9 vinegar-and-steam microwave cleaning gimmick that turned into a genuine best seller.
A small, mama-shaped plastic container you fill with vinegar and water, then microwave — the steam it produces loosens baked-on grime inside the microwave for easy wiping. Angry Mama Steam Cleaner is a newer name that's climbing — search interest and social mentions have been steadily increasing.
Dishwasher-safe parts and a clear warranty matter more than the marketing video suggests — check actual product reviews for durability complaints before buying, since listings that look near-identical can vary a lot in build quality.
