Why it worked
The video demonstrates a simple yet effective life hack for cleaning a paper towel holder, which is visually satisfying and easily replicable. The use of common household items and a surprising method (microwaving) likely contributed to its shareability and virality.
Summary
The video shows a person taking a cardboard tube from a paper towel holder, wetting it in the sink, and then covering it with baking soda and dish soap. The tube is then placed in a microwave and heated for two minutes. Finally, the person removes a clean, dry paper towel roll from the microwave.
