How Can I Remove Tough Stains From Grout?

Tough grout stains can be challenging, but several methods can help. Natural cleaners like baking soda and water paste or a mixture of equal parts white vinegar and warm water can be effective. Apply these solutions, let them sit, then scrub and rinse. However, avoid vinegar on natural stone tiles. Oxygen bleach is another option for tougher stains; follow the product instructions carefully. Commercial grout cleaners are also available and can be effective, but ensure they are safe for your tile and grout. Some people use toilet bowl cleaner in a pinch, but this should be tested in a small area first due to its harshness.
