Similarly, you may ask, how do you seal Sharpie on tile?

Decoupage medium seals it, or use a spray-on polyurethane sealer. Baking the piece is also an option if you haven't used alcohol on the tile. Allow the Sharpie to dry on the tile for a day or two to help the ink set, then bake the tile in a preheated 250-degree oven for 20 to 30 minutes.

Can you use rubbing alcohol on ceramic tile?

Ceramic tiles can almost always be cleaned with just a damp mop but, for dirty grout, add two tablespoons of rubbing alcohol to each gallon of water before mopping. Wipe up any excess water to avoid saturating the grout. Instead, add some mild dish soap to your mop water.
