Maintaining ceramic tile is minimal if done on a regular basis. It is truly a low-maintenance material.
For daily cleaning, sponge down your ceramic tile countertop or wall tile with the manufacturer's recommended tile and grout cleaners or with a non-abrasive household cleaner. Be sure to clean spills as quickly as possible so that the grout or tile does not become stained.
For heavier cleaning, there are cleaning products sold in your local grocery store that can be used to remove soap scum, hard water deposits, and mildew stains. You'll want to consult the cleaner's manufacturer instructions to make sure the product is compatible with your type of tile. After cleaning, rinse well and wipe dry for more shine. Textured tiles may require mild scrubbing with a soft brush or electric polisher/scrubber.
To avoid scratching the surface of the tile, never use abrasive cleaners or steel wool. Do not use bleach or ammonia, on a regular basis; these products can discolor your grout. Depending on your lifestyle, sealing of the grout joints on your countertop or wall tile may be an option. After the installation process is complete and your grout has had ample time to cure, sealing the grout can provide protection from dirt and spills, by slowing down the staining process.

Keep in mind that ceramic tile is very durable, but not indestructible. Do not use a ceramic countertop to sit or stand on, or as a cutting board. Ceramic tile or grout can crack or chip under extreme force.
Also, please remember, it is the responsibility of the homeowner to maintain all caulked areas.
