For cleaning water stains and oil stains. I tried the cleaning goods "Kitchen Sponge Surprise Fresh Shiny Cut Cleaner" sold by Sanko.
A polyester cleaner that "cleans can be removed with just water" due to the unevenness of the surface. You can cut it to the length you want with scissors. When I rubbed the white water stain that stuck to the faucet, it fell off and became shiny! The oil stains that had accumulated on the gas stove's trivets could be removed considerably, although it took some time to rub. It is also a nice point that even if dirt is removed, stainless steel and coating processing will not be damaged.
The impression is that the effect depends on the type of dirt and the number of years elapsed. After trying several things, I couldn't get rid of the scorched stains on the kettle and the stainless tea astringency that had accumulated over the years. Instead of trying to rub it off forcibly, it seems better to use it properly with a melamine sponge or add a drug.
It is available on various mail-order sites, and the price range is around 300 yen for items with a size of 10 x 50 cm. It can be used for various materials such as tiles, pottery, glass, and enamel, so why not give it a try?
