Tiles are a common material in home decoration, but how to clean them correctly to maintain their luster is a concern for many homeowners. First, avoid using hard brushes or abrasive cleaners to prevent scratching the surface of the tiles. It is recommended to use a soft sponge or cloth with a neutral cleaner. For stubborn stains, a cleaning product with a small amount of mild abrasive can be used, but ensure it does not damage the tiles. Regular waxing is also an effective method to maintain the luster of tiles, and it is suggested to do it every six months.
