Tile and grout do not always tolerate the same cleaner: glazed ceramic, porcelain, and natural stone respond differently to acids and abrasives. Identify the material first, remove grit dry, and use modest water so soil is not pushed deeper into porous grout.
Vacuum grit before mopping
Hard particles act like abrasive under a mop. Vacuum or sweep corners and grout lines thoroughly before adding water, especially in entries and kitchens.
Use a cleaner compatible with the tile material
Ceramic and porcelain usually tolerate neutral detergents, while marble, travertine, and other stone can be damaged by vinegar or acids. If the material is unknown, avoid aggressive descalers until it is identified.
Scrub grout with a mild product and brush
Work in sections and rinse residue so soil is not redeposited. A nylon brush is generally safer than metal tools that can erode or stain grout.
Dry and decide whether the grout needs sealing
After cleaning, let the floor dry before judging color. Some cementitious grout benefits from periodic sealing as directed, while epoxy and other systems have different maintenance needs.
