Step 1: Cleaning 

Just like you should clean walls before painting, floors need to be cleaned before staining grout. A bleach/water solution is a good way to make sure you kill any mold or mildew that is lurking and any general tile cleaner or mop solution with a bleach base is fine. Mopping the tile is enough for that part, but the grout itself needs to be scrubbed as well. A stiff sponge or scrubbing brush is the best way to go here, and you want to be thorough in your cleaning. The process can feel a little grueling, especially on a big floor, but it’s an absolute necessity for the best results. 

Step 2: Applying the Stain 

The good news is that the entire process is only three phases. The bad news is that the second step is a doozy. Grout stain is notoriously hard to get out of ceramic, so you need to be tough throughout the application process. If your tile has a glossy finish, then you can manage spills or drips by staying on the ball and quickly wiping up the wet stain with little worry. If you went for a less glossy finish, then you need to add even more care to your technique. In general, small, extra stiff brushes are your friend.  The stiffness gives you a little more control, and you obviously want a brush that is small enough to fit in between the tiles to avoid any mess. 

Once the stain is applied, wait 24 hours to let it completely dry and finish. On average, most stains require two coats to accomplish completely the look and color desired, but you should always decide on a case-by-case basis. For each coat, be sure to wait a full 24 hours before deciding on an additional layer.  

Step 3: Seal the Grout 

Once you are satisfied with the color, you want to consider sealing the grout. This not necessary in a bedroom or living room, but bathrooms, kitchens and any other floor that gets a lot of water exposure should be sealed. Any grout seal from the local store should work fine. Just follow the instructions on the bottle.
