You can take Lamisil with food or on an empty stomach. Even though the fungus may appear to go away sooner than 12 weeks (or 6 weeks for fingernail fungus), it is important that you take it for a full 12 weeks (6 weeks for fingernail fungus) to make sure that you kill each and every fungus cell.
Ceramic-tile floors can be cleaned easily with nothing but warm water, but be sure to sweep or vacuum first to remove any loose soil or grit. Never use a sponge mop to clean ceramic-tile floors. It will pull the dirt right into the grout tracks.
Tile Floor Cleaning Basics. Sweep or vacuum your glazed tile floors regularly to keep them from getting dull. Tiles may be resistant to dirt, but sand and grit can dull glazed surfaces. Clean tile with mild detergent and clean water, using a rag or chamois-type mop rather than a sponge mop. The latter pushes dirty water into grout lines and makes them harder to clean. Be sure to change the water frequently while mopping; dirty water equals a cloudy floor.
