You can safely use vinegar to clean ceramic or porcelain tiles, whether they are glazed or unglazed. For other types, however, like terracotta, marble or grante, we recommend you look for ph neutral cleaner that will not harm the material.
Grout that hasn't been sealed, needs to be resealed, or is in poor shape should not be cleaned with vinegar. The vinegar penetrates into the pores of the grout, further weakening the material. Over time, vinegar will deteriorate the condition of the grout by etching or wearing it away.
The most common and effective homemade grout cleaner is a mixture of baking soda, hydrogen peroxide, and dish soap. Cream or tartar and lemon juice is the best all-natural solution for whitening. Avoid using highly-acidic solutions like vinegar because they can corrode grout.
What do professionals use to clean grout? Whether you believe it or not, most professionals use a solution of white vinegar and water with a 1:1 ratio.
Dawn and Vinegar Grout Cleaner
Heat a cup of 1-to-1 vinegar and water in the microwave for about a minute. Pour it into a spray bottle and add a cup of Dawn dish soap. Carefully spray the mixture on your grout lines. Let it sit for 5-10 minutes longer if you have really dirty grout.
So the answer to the titular question is vinegar. Vinegar is better for cleaning. But that's because bleach isn't intended for cleaning, but for disinfecting. And, by the way, if you want to use bleach for disinfecting, make sure the area you want to treat is clean (and rinsed clean, if you used vinegar!)
Avoid Vinegar and Baking Soda
Vinegar and other acids are also a bad idea for stone tile because the acid can etch the stone. Another widely praised household cleaner, baking soda, is alkaline (not acid), but it is not very effective as a grout cleaner.
In a bowl, combine 2 cups water, 1.5 cups baking soda, 1/3 cup vinegar, and 1/3 cup Dawn. Using a spoon, gently stir, making sure there are no lumps. Add the mixture to a clean spray bottle. Spray the floor with the mixture.
For stubborn shower stains, soap scum and grime, mix one cup of warm water, two cups of white vinegar and one teaspoon of a vegetable-based dishwashing soap in a spray bottle. Spray the solution on the shower walls, let it work for 15 minutes and use a sponge to scrub off scum and grime.
Vinegar is one of the best multi-purpose cleaners available at every house. It is safe to use on laminate, vinyl, porcelain, and ceramic tiles. A few drops of vinegar can help you restore the original look of your tile floors.
Mix Cleaning Solution
To remove everyday dirt and debris, mix two parts baking soda with one part water. For stained or discolored grout, mix two parts baking soda with one part vinegar. And if you have coarse or fragile tiles, mix two parts baking soda with one part hydrogen peroxide.
To clean your grout, combine one-part 3% hydrogen peroxide and one-part water into a spray bottle. Spray your grout generously and let the solution sit for about 1 hour, to allow time to work. Rinse the area with water and wipe clean with a microfibre cloth.
White grout gets dirtier when it's used in the shower. To date, we have had no negative experiences with white grout used on our tile floor in the bathroom. You have to be pretty vigilant to keep white grout clean in the shower and clean fairly regularly to keep white grout clean on the floor.
Method 2: How to Get Grout White Again with Lemon Juice or White Vinegar. Saturate the grout with lemon juice, a mild disinfectant that gets rid of grout stains naturally. You can also use white vinegar for chemical-free grout cleaning.
Spray grout with equal parts vinegar and warm water.
Fill a spray bottle with a half-and-half solution of vinegar and warm water. Spray the mixture on the grout, let it stand for 5 minutes, then scrub the surface with a stiff brush. Avoid using vinegar on unsealed grout.
In a small bowl, make a paste with baking soda and water. Dip your toothbrush or grout brush in the paste and work it into the grout. Spray the area with your vinegar and water solution. The vinegar will cause the baking soda to bubble up and will start to work away that nasty soap scum.
The vinegar combined with the baking soda will create a bubbly reaction, which will get rid of soap scum, limescale and mould. Be sure to work the baking soda into the grout lines, removing all build-up.
