Grout may be small, but it makes a big impact on how your tile floors and walls look. Unfortunately, it also traps dirt, stains easily, and is one of the hardest things to keep clean—especially without damaging the surrounding tile.
Here’s the best way to safely clean grout while protecting your tile’s finish, straight from the pros at Bay Shore Cleaning & Restoration.
Why Grout Gets So Dirty
Grout is porous, which means:
- It absorbs spills, soap scum, and grime
- It’s prone to discoloration
- Regular mopping doesn’t reach deep enough
Over time, grout lines can darken or even develop mildew—making your tile look older than it is.
What Not to Use to Clean Grout
Before we dive into the proper methods, here’s what to avoid:
- Vinegar or lemon juice: These acidic cleaners can erode grout and dull natural stone.
- Bleach: Can weaken grout over time and stain nearby tile.
- Wire brushes or harsh scrubbers: May scratch tile surfaces or break grout sealants.
If your tile is natural stone (like marble or travertine), be extra cautious—those materials are sensitive to acidic or abrasive cleaners.
Safe, Effective Ways to Clean Grout at Home
Here’s a trusted method that balances cleaning power with surface safety:
- Use a pH-neutral cleaner: Choose a tile & grout cleaner that’s specifically labeled as pH-neutral. These are safe for stone, ceramic, and porcelain.
- Apply with a soft brush: Use a soft-bristle brush or an old toothbrush to gently agitate the grout lines. Avoid scrubbing too hard.
- Let the solution sit: Give the cleaner 5–10 minutes to work into the grime—this loosens stains without harsh chemicals.
- Wipe clean with warm water: Rinse thoroughly and wipe dry with a microfiber towel.
- Reseal if needed: If you haven’t sealed your grout in the past year, consider reapplying a grout sealer to prevent future staining.
