To clean ceramic floor can be a frustrating task due to the difference of matter that the tile is made and the unglazed grout. Ceramic floors add value to the house, usually found in bathrooms, hallways and kitchens. It is the same as all plants, require cleaning periodically and cleaning a ceramic floor is not the same as cleaning of a vinyl or wooden floor. What makes it difficult is that the tile is glass, but the grout is made of cement mortar between the tiles, not glazed that is stained or dirty much easier than the tile. Although Grout may have an insulator applied, it is still not as durable and resistant to stains and dirt as ceramic tile. If the nozzle is dirty the whole floor looks dirty.
Then, How to clean it?
There are many household cleaning products available to do the job, however none of them do a much better job than white vinegar and warm water.
Vinegar is A mild blend of tartanic amd citric acids. A large cleaning solvent is made when mixed with lukewarm water. For cleaning the grout, mix 50% water, 50% White vinegar and apply to the grout with a sponge. Let me act for a few minutes and scrub the grout with a toothbrush. A second application may be necessary if the grout is heavily stained. Use the sponge to absorb debris and clean the floor with a mild detergent.
The same vinegar and water solution can be used to clean the stains on the ceramic tile. Use a sponge to clean the entire floor and another sponge to dry. Because vinegar is an acid that removes any grout sealant it will have to re-seal the grout with a small brush. Apply two sealant applications, leave completely dry between applications. Grout Sealant is available at most home supply centers or a tile store for your convenience.
To protect your hands I recommend that you wear rubber gloves for handling vinegar solution and apply grout sealant. It is not necessary to use an electrical machine to or polish the ceramic floors. Excessive use of this machine can remove the enamel from the tiles leaving it with a matte finish. I do not recommend using Clorox to clean the ceramic floors, as it tends to yellow the mosaic and erode the grout.
