Important note: To avoid damage to grout, it's best to avoid any acidic cleaners, such as vinegar or chlorine bleach, as they will damage and erode your grout over time.
A 50/50 mix of white vinegar and warm water can combat tough stains. Make your own grout cleaner with pantry products. Fill a spray bottle with a 50/50 solution of white vinegar and warm water and stir it until it's fully integrated. Then spray the solution liberally onto the grout.
If you know your grout has been sealed but it has accumulated heavy dirt or mild stains, turn to vinegar, that trusty old household staple.

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.
Bleach is safe when used as directed
It is safe for use on typical hard, nonporous surfaces in showers and bathrooms like glazed ceramic tile, vinyl, stainless steel, fiberglass and sealed grout. To protect surfaces, always follow instructions and don't use a stronger dilution or longer contact time than recommended.
When your grout gets grungy Mandy people grab for the standard bleach and a toothbrush to get their grout lines looking white and sparkling again, but it won't work for colored grout. The purpose of colored grout is the color, and bleach will ruin that color.
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.
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.
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.
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.
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.

Hydrogen peroxide won't damage normal tiles or colored grout. However, you shouldn't use it on polished marble. Cleaning with hydrogen peroxide and baking soda is a great way to remove stubborn stains from your grout.
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.
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.
You can also use white vinegar for chemical-free grout cleaning. Simply pour vinegar from the bottle into the cap and pour it over the dirty grout lines. Allow the lemon juice or vinegar to sit for 10 to 15 minutes. Then, scrub with a small brush or old toothbrush.
Cleaning solutions that contain bleach or ammonia will not only work to erode your grout over time, they will cause your grout to become even dirtier by leaving a film behind, which attracts dirt.
The dark spots on grout are most likely the result of mold, mildew or plain old dirt buildup.
The easiest way to clean grout without scrubbing involves hydrogen peroxide and baking soda. Mix the two into a paste with some dish soap and apply to the grout lines. Alternatively, you can use a cleaning solution of water, vinegar, lemon juice, and baking soda.
