Tile & Grout: When to Clean vs. Reseal
Tile floors are popular in Arizona homes for good reason—they're durable, cool underfoot, and relatively easy to maintain. But over time, grout lines can become discolored and stained. Should you have them cleaned, sealed, or both? Let's clarify the difference.
Cleaning vs. Sealing: What's the Difference?
Tile & Grout Cleaning Cleaning removes dirt, grime, mold, and stains that have built up in the porous grout lines. We use:
- Professional-grade degreasers
- Specialized brushes and agitation tools
- High-temperature steam cleaning
- Powerful extraction to remove embedded dirt
When you need it: When grout looks dingy, discolored, or has visible stains.
Grout Sealing Sealing applies a protective barrier to clean grout lines, preventing future staining and moisture penetration.
When you need it: After cleaning, or when grout is clean but unprotected.
Signs Your Grout Needs Cleaning
- Grout lines are darker than they used to be
- Visible stains or discoloration
- Mold or mildew growth (especially in bathrooms)
- Grout feels rough or gritty to the touch
Signs Your Grout Needs Sealing
- Water soaks into grout instead of beading up
- Grout hasn't been sealed in 1-2 years
- You've just had grout professionally cleaned
- You want to prevent future staining
The Ideal Process
For best results, we recommend this sequence:
- Deep clean tile and grout to remove all dirt and stains
- Allow 24-48 hours for grout to dry completely
- Apply sealer to protect clean grout from future staining
- Maintain with regular mopping using pH-neutral cleaners
How Often Should You Clean and Seal?
Cleaning: Every 12-18 months for most homes, more frequently for high-traffic areas or homes with pets.
Sealing: Every 1-2 years, or after each professional cleaning.
DIY vs. Professional Service
DIY Cleaning Store-bought grout cleaners can help with light maintenance, but they rarely match professional results. Many contain harsh acids that can damage grout over time.
Professional Cleaning Professional equipment reaches deep into porous grout, removing years of buildup that surface cleaning can't touch. We also use pH-balanced cleaners that won't damage your tile or grout.
Common Mistakes to Avoid
- Sealing dirty grout - This locks in stains and dirt
- Using harsh chemicals - Bleach and acidic cleaners can damage grout
- Skipping sealing - Unsealed grout absorbs stains quickly
- Waiting too long - Deeply set stains become harder to remove
Arizona-Specific Considerations
Our hard water can leave mineral deposits on tile and in grout. Professional cleaning removes these deposits before they become permanent. Regular sealing also helps prevent hard water staining.
The Bottom Line
Think of it this way: cleaning removes what's already there, while sealing prevents future problems. For the best-looking, longest-lasting tile floors, you need both.
