After grouting, clean floors using a wet/dry vacuum or mop, followed by thorough rinsing with clean water to neutralize any acid residues left behind.
Here's a more detailed explanation:
1. Initial Cleanup:
- Remove Excess Grout: Once the grout has slightly hardened (as per the grout manufacturer's instructions), use a grout float held at a 45-degree angle to remove excess grout diagonally across the tiles. Avoid digging into the grout lines.
- First Wipe: Use a damp sponge (not soaking wet) to wipe the tiles, removing as much of the remaining grout haze as possible. Rinse the sponge frequently in clean water. This initial wipe is crucial to preventing the grout haze from hardening.
2. Grout Haze Removal:
- Multiple Washes: Continue washing the floor with a clean sponge and clean water. Change the water frequently, as dirty water will only spread the haze. You may need to repeat this process several times.
- Use a Grout Haze Remover (if necessary): If a stubborn grout haze remains, use a commercial grout haze remover. Always follow the manufacturer's instructions. Most haze removers are acidic.
3. Neutralization (Especially After Acidic Cleaners):
- Rinse Thoroughly: After using any acidic cleaner, thoroughly rinse the floor with clean water. This neutralizes any remaining acid residue, which could damage the tiles or grout over time.
- Wet/Dry Vacuum or Mop: Use a wet/dry vacuum to remove the dirty water, or mop the floor with clean water and wring out the mop thoroughly.
4. Final Polish:
- Buff with a Clean Cloth: Once the floor is dry, buff it with a clean, dry cloth to remove any remaining residue and restore its shine.
Important Considerations:
- Timing is Key: Start cleaning when the grout is firm enough to resist being pulled out of the joints but hasn't fully hardened. Refer to the grout manufacturer's instructions for the recommended drying time.
- Use Clean Water: Dirty water will only redeposit grout haze. Change your water frequently.
- Avoid Over-Wetting: Excess water can weaken the grout and cause efflorescence (a white, powdery deposit).
- Test in an Inconspicuous Area: Before using any cleaning product, test it in a small, hidden area to ensure it doesn't damage the tile or grout.
- Safety First: Wear appropriate safety gear, such as gloves and eye protection, when working with grout and cleaning chemicals.
