Not only can it quickly dissolve grease and grime in my bathroom, but when combined with baking soda, I’ve also used it to unclog my drains successfully.

That seal is essential because it protects the surface from staining, etching, and general wear.”What’s more, repairing damage to expensive materials such as marble, granite, or other natural stones can be costly. “It’s very rarely an immediate problem. That’s why people don’t always connect the cleaning product to the damage.
