Clean spills promptly after they occur. If a spill happens on your ceramic tile floor, clean it up as soon as possible. The longer a stain sits on your ceramic tile, the harder it will be to remove. Use mops on large spills and absorbent cloths on smaller spills.
Clean your grout. The grout is the sunken area bordering each ceramic tile. Over time, it can become discolored and gross. To keep it clean, mix baking soda and water in equal amounts. Coat the grout with the paste. Allow it to sit for several hours (or even overnight). Scrub the grout vigorously with an old toothbrush or a stiff-bristled brush. Wipe the paste scum away with a sponge soaked in warm water.
If you have a large amount of grout to scrub, purchase a grout brush from the cleaning supplies section of your local store. For an extra boost of cleaning power, fill a spray bottle with vinegar and spray the paste after you apply it.
The frequency with which you clean your grout is up to you. Clean your grout as often as you like, or when it begins to show discoloration. Floors that are used more heavily will require more frequent cleaning. If you have children, pets, and/or walk about your home with shoes on, you’ll need to clean your grout more often.
Use the least abrasive means possible to clean. When cleaning ceramic tiles, always start with just water. Test any commercial cleaning solution on a small and out-of-sight portion of your ceramic tile before you apply it to a larger or more visible area of your tile. This will help you ensure that the solution does not discolor or otherwise damage your tile. Avoid using abrasive cleaners or creams containing gritty ingredients like silicate.
