Your stone tile can last for generations if you learn how to clean your natural stone shower the right way. There are some things you are going to think you should use, only to find out they pitted your stone. So, here are some general rules to follow and your tile will be beautiful for a very long time.
How to Clean Your Natural Stone Shower
Unfortunately, most people will start pouring diluted vinegar all over their stone tiles, assuming that what works great for porcelain tiles will be great for stone tiles, too. This is not how to clean your natural stone shower. It's exactly what you should not do.
Vinegar is an acid and acids do a wonderful job on loosening and removing soap scum. Only citric acid is better. The problem is, any acid will breakdown your natural stone tiles. If you’ve been using vinegar, you are probably noticing some pitting on the top of the stones and maybe the edges are beginning to crumble. This is what acid will do to stone.
The best way to clean these tiles is by using a gentle pH-neutral cleaner like dishwashing liquid mixed into water like you're going to wash dishes. Use a soft cloth, like sections of an old t-shirt, and clean the stone by dipping it into the soapy water and scrubbing then rinse. It helps to do this right after someone takes a hot shower. The hot water will soak the soap scum and loosen it up, making it easier to clean.
The grout can be scrubbed with a toothbrush while you’re using the cloth and soapy solution. Avoid products sold for grout cleaning as they usually injure the stone.
Rough cloths and plastic bristle scrub brushes will break down the stone over time. It is best to stick with just old soft cloths and toothbrushes.
Rinse well after cleaning. To keep your shower needing fewer cleanings, use a squeegee to remove the water from the walls and floor after every use. This will keep the soap scum from building up.
