How to Remove Grout on Porcelain Tile

Porcelain tile is durable and long-lasting, and it makes a beautiful addition to a bathroom, kitchen or even a backsplash. Like other tiled surfaces, porcelain tile usually requires grout to fill in the joints. Grout is a gritty substance that not only helps to hold the tiles together, but also protects the tile. Grout can be messy to install; it is not uncommon for excess grout to end up on the face of the tile. Removing grout on porcelain tile is easy when the grout is still wet. Once the grout dries onto the tile, the job becomes more challenging.

Removing Wet Grout

Step 1

Use a grout float to go over the tile, removing as much grout as possible. Run the float diagonally across the tile, scooping up the excess grout. Angle the float when running it across the tile and take care not to remove the wet grout from the joints.

Step 2

Fill a bucket with warm water. Dip a sponge into the water and wring it out.

Step 3

Wipe up the grout from the tile by moving the sponge in circular motions. Rinse out the sponge frequently in the bucket of water. Discard and replace the water in the bucket as it becomes soiled.

Step 4

Continue to wipe down the tile until all you are able to remove all the grout. Buff the tile with a dry cloth.

Step 5

Remove the grout haze that will likely form on the tile. The haze may take a while to form. Scrub the tile with a dry rag, shaking the rag frequently to remove debris. Go over the tile with a damp sponge. Repeat this process several times, or until the haze disappears.

Removing Dry Grout

Step 1

Fill an empty spray bottle with water. Moisten the grout slightly to make it softer and easier to remove.

Step 2

Scrape as much of the grout from the porcelain tile as possible. Use wooden sticks rather than metal to scrape the grout to avoid scratching the tile.

Step 3

Discard the clumps of grout that you were able to remove from the tile. Wipe the tile with a wet rag to further remove the grout.

Step 4

Spray more water onto the remaining grout. Moisten a nylon scouring pad with water.

Step 5

Scrub the tile gently with the wet scouring pad. Continue to add more water to the tile, as needed, to keep the grout wet.

Step 6

Dry the tile with a soft cloth. Inspect the area to see if any grout remains.

Step 7

Mix a white vinegar and water solution into an empty spray bottle if the grout is still on the tile. Use 10 parts water to one part vinegar.

Step 8

Spray the vinegar solution onto the tile. Allow it to soak into the grout on the tile for a few minutes.

Step 9

Wipe the area clean with a damp sponge. Rinse the area with a rag and plain water.

Step 10

Dry the tile with a clean cloth. If grout or grout haze remains on the tile, apply more vinegar solution.
