Tile & Grout Cleaning: What You Can DIY (and When to Call a Pro)
March 2026 · 4 min read
Tile floors are durable, but grout lines are a magnet for dirt, grime, and mildew. The good news? Some maintenance is easy to do yourself. The key is knowing when DIY stops working and professional cleaning starts.
What You Can Do Yourself
✅ Weekly Maintenance
- Sweep or vacuum tile floors 2-3 times per week to prevent grit buildup
- Mop with warm water and a pH-neutral cleaner (avoid bleach on colored grout)
- Wipe up spills immediately — grout is porous and absorbs stains
✅ Monthly Deep Clean (DIY)
- Make a paste with baking soda and water, apply to grout lines
- Spray white vinegar over the paste — let it fizz for 5 minutes
- Scrub with a stiff brush (old toothbrush works for small areas)
- Rinse thoroughly and dry with a clean cloth
When to Call a Pro
DIY works for surface-level maintenance. But grout is porous — over time, dirt and bacteria penetrate deeper than any scrub brush can reach. Here are the signs it's time to call a professional:
🟤
Grout has changed color
If your grout was white and is now brown, grey, or black — the staining is too deep for DIY.
🦠
Mold or mildew smell
If you can see or smell mold in grout lines, especially in bathrooms, professional extraction is needed.
🧽
Scrubbing doesn't help
If you've tried baking soda, vinegar, and commercial cleaners with no improvement — the dirt is embedded.
📏
Large areas
Scrubbing a full kitchen floor on your hands and knees isn't practical. Pros have equipment that covers large areas efficiently.
🏠
Before sealing
If you want to seal your grout (highly recommended), it needs to be professionally cleaned first for the seal to bond properly.
Pro Tip from Garo
“The biggest mistake homeowners make is using too much water on tile floors. Water seeps into grout and sits there. That's how you get mold. Our low-moisture method cleans the grout without soaking it — it's the same reason we use it on carpet.”
