Greasy Range Hood Filter? This $1 Japanese Trick Dissolves It Fast

In a cramped Tokyo apartment kitchen, where tempura is deep-fried almost nightly, a home cook lifts an aluminium range hood filter caked in a thousand dinners' worth of oil, drops it into a bowl of hot water and one spoon of white powder, and twenty minutes later pulls out bare, gleaming metal. No scrubbing. No fumes. No replacement. That brown varnish baked into your filter is not ordinary grease anymore. Heat has polymerised it into a hard, fatty coating chemically bonded to the metal, which is exactly why every degreaser spray and every sore-fingered scrubbing session has failed you. The cleaning-product aisle has no incentive to explain the fix, because it costs about a pound and lasts months. The Japanese have used it for generations. In this video you will learn: ✅ Why repeated heat turns soft oil into a varnish-like polymer that bonds to aluminium ✅ The exact baking soda saponification reaction that turns grease back into soap and rinses it away ✅ The 20-minute hot-water soak, step by step, with the right ratio per litre ✅ The boiling-pot rescue method for filters a year or more past cleaning ✅ Why caustic oven cleaner and the dishwasher will wreck an aluminium filter ✅ The 30-second weekly habit that means you never deep clean again If this changed how you see the thing above your stove, hit subscribe for a new Japanese household method every week.
