1. Vinegar soak: Want to clean the bathtub. For scale on the walls and faucets, soak a rag in vinegar, then cover the stubborn scale and let it sit overnight. The next morning, mix soda ash and vinegar into a paste, then dip a toothbrush into the paste and scrub the area to clean it.
2. Wipe with old newspapers: Use old newspapers to wipe the bathtub to remove accumulated dirt. You can also use a clean cloth or brush dipped in decontamination powder to wipe gently, and then rinse with clean water.
3. Special cleaner: If you don't care about cost, use special bathtub cleaner! Not only can it effectively remove common soap scum on the bathtub surface. It is also effective against organic aged yellow scale that is difficult to remove, saving time and effort, and does not damage the surface of the bathtub.
