If you will tell me proper home type and tile type i can help you. If can share photos of your floor I can give you very good tips. But now these are some dos and don'ts tips which can help you. Do clean up spills as quickly as possible so your grout won’t become stained. Don’t use steel wool, scouring powders, or other abrasives that can scratch the finish of your ceramic tile. Do remember that while ceramic tile is very durable, it’s not indestructible and may crack or chip under extreme force. Don’t use bleach or ammonia-based cleaners — these products can discolor your grout if used too often. Do take the proper precautions when moving heavy objects across a ceramic tile floor. Do cover furniture and table legs with protectors to guard your floor against scratching. Do remember that if a repair is necessary, the replacement product may be a slightly different dye lot and/or texture than the original tile, however, with time and usage, the replacement tile will blend in with its neighbors. Caulking and Sealing Once your tile has been laid and grouted, it’s your responsibility to caulk areas that may be exposed to water. Caulking will prevent expensive subsurface damage and keep the tiled areas looking as good as new.
