🌸 What is Grout, and Why Does It Get So Dirty?

Grout is the filler between your tiles. It’s porous, which means it absorbs water, dust, and grease — making it prone to stains, mould, and discoloration over time.

Good news:
With a few easy steps and the right tools, you can get it back to looking fresh and clean.

✨ How to clean tile grout efficiently and effectively

📌 Method 1: Baking Soda Paste + Vinegar Spray (Fizzy Lift Hack)

Best for: Everyday dirt and mild grime.

How to Do It:

• Mix 2 parts baking soda with 1 part water to form a paste.
• Apply directly to grout lines.
• Spray white vinegar over the paste — it will fizz as it lifts the dirt.
• Scrub using an old toothbrush.
• Wipe clean with water.

Why it works: The fizzing action helps loosen dirt from the grout surface without harsh chemicals.

📌 Method 2: Baking Soda + Vinegar Paste (Deep Clean Mix)

Best for: Stubborn, set-in stains and discolored grout.

How to Do It:

• Mix equal parts baking soda and vinegar to form a thick, foamy paste.
• (Optional) Add a squeeze of lemon juice for natural bleaching.
• Apply generously to grout lines with a toothbrush.
• Let it sit for 5–10 minutes to break down tough stains.
• Scrub well and rinse with clean water.

Why it works: The thick paste sits longer on the grout, giving it extra time to penetrate deeper stains.

✅ Key difference:

• Method 1: Paste first → spray vinegar to activate fizz → scrub
• Method 2: Mix both together into a paste (foamy) → apply → let sit longer for tough stains

📌 Method 3: Baking Soda & Hydrogen Peroxide Paste (Whitening Power Clean)

Best for: Tough stains, mold, and yellowed grout.

How to Do It:

• Mix 2 parts baking soda with 1 part hydrogen peroxide to form a thick paste.
• Apply generously along grout lines.
• Let it sit for 10 minutes.
• Scrub with a toothbrush or grout brush.
• Rinse with warm water.

Why it works: Hydrogen peroxide penetrates deep into porous grout and breaks down stains, while baking soda gently scrubs without damaging tiles.

Bonus Tip:
If you want to level it up for mold-prone bathrooms, add a few drops of tea tree oil to the mix for natural anti-fungal properties.
