Left a pleasant scent
Mild whitening effect
Downsides:
Removing lemon pulp afterward was messy
Not strong enough for deep or old stains
Verdict: Great for light maintenance and a natural approach, but not powerful enough for heavy grime.
Method 2: OxiClean
I mixed 1 scoop of OxiClean with warm water and applied it to the grout. After letting it sit for 10 minutes, I scrubbed using the same green pad and wiped everything clean with a damp cloth.
Results:
Noticeable improvement in brightness
Removed more embedded dirt than lemon juice
Easier cleanup than citrus pulp
Downsides:
May need a second application for tougher stains
Can be slippery on tile surfaces (caution while scrubbing)
Verdict: A solid all-purpose solution — good for routine deep cleaning without harsh chemicals.

Method 3: Sulfamic Acid Cleaner
I followed the package instructions carefully and applied the sulfamic acid solution to the grout. This required the most caution, as it’s a stronger chemical. I wore gloves and ensured good airflow.
Results:
Hands down, the most dramatic results
Removed deep, old stains and restored grout color
Minimal scrubbing required
Downsides:
Strong fumes
Requires careful handling and PPE
Not suitable for all tile types (avoid natural stone)
Verdict: Best for heavily soiled or neglected grout, but use with care. Definitely not for everyday cleaning.
Final Thoughts: Which Grout Cleaner Should You Use?
Method Best For Effort Needed Cleaning Power
Lemon Juice 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.
