Can you remove caked in grout from slate tile AFTER it has been sealed?

Yes, it is possible to remove caked-in grout from slate tile after it has been sealed, but it may require a bit more effort and the right cleaning products. Here's a step-by-step guide to help you remove the grout:

1. Prepare the cleaning solution:

- Mix a solution of warm water and a heavy-duty tile and grout cleaner.

- Follow the manufacturer's instructions for the recommended dilution ratio.

2. Apply the cleaning solution:

- Apply the cleaning solution to the affected areas with a sponge or a soft-bristled nylon brush.

- Make sure to work in small sections to prevent the solution from drying out.

3. Scrub the grout:

- Gently scrub the grout lines using the brush, applying moderate pressure to loosen the caked-in grout.

- Be careful not to use excessive force, as it may damage the slate tile.

4. Let it sit:

- Allow the cleaning solution to sit on the grout lines for the recommended time stated on the product label, typically around 5 to 10 minutes.

5. Rinse thoroughly:

- Rinse the area thoroughly with clean water to remove the cleaning solution and loosened grout.

- Use a damp cloth or sponge to wipe away any residual cleaner and rinse water.

6. Repeat as necessary:

- Repeat steps 2-5 if necessary for stubborn grout stains.

- Be patient, as removing caked-in grout after sealing may require multiple attempts.

7. Dry the tile:

- Allow the slate tile to dry completely before walking on it or applying any additional sealants.

Additional tips:

- Test the cleaning solution on a small, inconspicuous area of the tile to ensure it doesn't cause any damage or discoloration before applying it to the entire surface.

- Avoid using harsh or acidic cleaners, as they can damage the slate tile and the sealer.

- If the grout is heavily stained or the sealer has been compromised, you may need to have the tiles professionally cleaned or re-sealed.

By following these steps, you can safely remove caked-in grout from slate tile, even after it has been sealed.
