Light dirt, eco-conscious users Moderate ☆☆☆
OxiClean General deep cleaning Moderate ☆
Sulfamic Acid Tough, set-in stains Low
My Recommendation
If your grout is mildly dirty or you prefer a natural method, start with lemon juice. For general cleaning that doesn’t require a hazmat suit, OxiClean hits the sweet spot. But for grout that’s been ignored for years, sulfamic acid cleaner is your best bet — just be sure to use it responsibly.
