When Is a Commercial Grout Cleaner a Better Choice?
Homemade cleaning methods are useful for everyday household dirt, but very old stains may require a specialized grout cleaner. Choose a product specifically compatible with your tile and grout type, and follow the instructions on the label carefully.
Avoid highly abrasive tools, such as metal brushes, because they can scratch tile surfaces and damage the grout. A stiff nylon grout brush or an old toothbrush is generally a safer option.
