The cleanliness of grout lines in restaurants in Jingili has become increasingly problematic with the use of various tile types in restaurants. Generic cleaners and mopping may seem effective initially, but over time, dirt and soil build up, causing tiles to appear dull and grout lines to darken.
If you run your finger along a grout line, it will likely feel greasy. This is due to conventional cleaning methods that tend to push dirt deeper into the porous grout. Until now, the options were limited—either accept the grime or undergo costly tile replacement.
