Take care that you don’t spread the paint to the grout as you clean the tile. If you get wet paint on grout, wipe it up as fast as possible.

Use caution if you’re cleaning glass or marble tiles, since it’s easy to accidentally scratch the material. If you don’t have a utility knife, use a putty knife, razor blade, or painter’s knife. Always be careful when you handle a sharp utility knife.

Open a window or turn on a fan to improve ventilation in the room since you don’t want to breathe in paint fumes.

Add a few spoonfuls of baking soda to the solution for even deeper cleaning. Baking soda is naturally abrasive so it can remove the paint but it won’t scratch your tile. Skip the vinegar if your tiles are made of limestone. Acidic products can wear the material out.

It’s a good idea to test the product on a small, inconspicuous area before you use it on your tile. In a pinch, you can try using nail polish remover since it’s essentially a solvent. It’s safe to use on ceramic as long as you don’t let it sit for more than a few minutes.

Avoid using an abrasive pad like steel wool or sandpaper, which can damage tile—even sturdy ceramic.

To dilute bleach, combine 3⁄4 cup (180 ml) of bleach with 1 gallon (3. 8 L) of water in a large bucket. Avoid using bleach if you have colored grout. Instead, use vinegar, hydrogen peroxide, or a baking soda paste made with water.
