How to Remove Grout From Tile Step 1: Grind and scrape out the old grout

Attach the removal unit and set the bit depth to 1/4 in. Run the tool guides between the tiles and grind through the old grout. Clean joints with a grout saw.

Renewing old grout has always involved long hours of hacking away at old, worn grout with a tiny grout saw. Simplify the job by purchasing a grout removal kit that attaches to a Dremel tool. (See photo below). It has a high-speed carbide bit that effortlessly chews away old grout, and guides that keep you from chipping the tile edges. Make sure to wear safety glasses while grinding (Photo 1). Use the grout saw to scrape out edges and corners and to clean out the joints.

Buy a Grout Removal Attachment

A grout removal kit contains the grinding guide and a grout saw for cleaning along edges where the grinder can’t reach. It’s designed to fit a Dremel tool.

Using a grout float, push the grout diagonally across and into the vacant joints.

Vacuum up any dust or debris left after the grinding process. Take a chunk of your current grout to a home center or tile shop to find a match. Also buy a latex additive to mix into the new grout to make it more durable. Mix the grout slightly thicker than peanut butter and then apply it (Photo 2).
