Tile, Grout & Bathroom Cleaning Tile, Grout & Bathroom Cleaning Comet and Ajax cleanser always seemed to get my tiles and sink really clean. You can also use the Tilex line of spray products. They work all over the bathroom, on tile, sinks, tub and faucets. I also use a mixture of vinegar and water on my bathroom ceramic tile. I use my vinegar and water mixture on almost every hard surface in our home. I use a 50/50 mixture (half vinegar and half water) and put it in a spray bottle. I also add 8 to 10 drops of an essential oil for fragrance. Lavender essential oil and lemon essential oil are a couple of my favorites. I then spray the mixture on the surface I want to clean and just wipe it with a soft cloth. It does a great job of cleaning and disinfecting most surfaces in the home. The only place you do not want to use this mixture is on any granite surface in your home such as granite counter tops in your kitchen. The vinegar is too acidic and could damage the granite.
