The answer to 'how often to clean tile and grout cleaning' is that most experts recommend cleaning tile and grout every 6-12 months, depending on the amount of foot traffic and spills. Regular cleaning helps prevent dirt, grime, and bacteria from building up, which can lead to discoloration and damage over time.
For high-traffic areas like kitchens and bathrooms, cleaning every 6 months is ideal. For lower-traffic areas like entryways or hallways, cleaning once a year is usually sufficient. It's also a good idea to clean tile and grout after any major spills or events that leave the floors particularly dirty.
