Let’s get started!
What Is Grout and Why Does It Get Dirty?
Grout is a mixture of cement, sand, and water used to fill gaps between tiles. It’s porous, meaning it absorbs liquids and dirt easily. This makes it a magnet for:
- Mold and mildew (common in showers)
- Dirt and grime (especially on floors)
- Food stains (in kitchen tiles)
- Hard water stains
Because grout is rough and absorbent, regular mopping or wiping isn’t enough. You need deep cleaning methods to restore its original color.

How to Clean Grout in the Shower
Shower grout gets dirty fast because of constant moisture. Mold and soap scum build up quickly. Here’s how to clean it properly:
1. Baking Soda and Vinegar Method
- Mix baking soda and water to make a thick paste.
- Spread it on the grout lines.
- Spray white vinegar over the paste (it will bubble).
- Scrub with a stiff brush or old toothbrush.
- Rinse with warm water.
This method works great for mold and mildew.
2. Hydrogen Peroxide for Tough Stains
- Pour hydrogen peroxide directly on stained grout.
- Let it sit for 10-15 minutes.
- Scrub with a brush and rinse.
Hydrogen peroxide kills mold and brightens grout.
3. Bleach for Heavy Mold (Use Carefully)
- Mix 1 part bleach with 10 parts water.
- Apply with a sponge or spray bottle.
- Let it sit for 5-10 minutes (don’t let it dry).
- Scrub and rinse well.
Warning: Bleach can damage colored grout. Use only on white grout in well-ventilated areas.
How to Clean Grout on Tile Floors
Floor grout collects dirt, grease, and foot traffic stains. Here’s how to clean it:
1. Steam Cleaning (Best for Deep Cleaning)
- Use a steam cleaner with a grout attachment.
- The high heat loosens dirt and kills bacteria.
- Wipe with a clean cloth afterward.
Steam cleaning is chemical-free and very effective.
2. Oxygenated Bleach (Safe for Colors)
- Mix oxygenated bleach (like OxiClean) with warm water.
- Apply to grout and let it sit for 15-20 minutes.
- Scrub and rinse.
This method removes stains without harsh chemicals.
3. Dish Soap and Hot Water for Light Dirt
- Mix a few drops of dish soap in hot water.
- Scrub grout with a brush or toothbrush.
- Wipe clean with a damp cloth.
Great for regular maintenance cleaning.

You don’t always need expensive cleaners. Try these DIY solutions:
1. Baking Soda & Hydrogen Peroxide Paste
- Mix equal parts baking soda and hydrogen peroxide.
- Apply, scrub, and rinse.
2. Lemon Juice & Salt Scrub

Lemon juice acts as a natural bleach.
