There are a number of commercially available grout cleaners you can choose from. You can also mix your own grout cleaning solution using a handful of general household chemicals you probably already have. Vinegar, baking soda, ammonia, hydrogen peroxide and dish detergent can be combined separately in different combinations to produce a solution that will help you scrub away grout stains.
Many household cleaning products made for bathrooms and kitchens usually contain bleach. While bleach can be an effective tile and grout cleaner and disinfectant, many tile experts believe it can also degrade grout over time. If you use a bleach solution to clean grout, water it down heavily. Use a mix of 1-part bleach to 5-parts water.
Safety Alerts!
Never mix ammonia and bleach. Mixing the two can create a toxic fume that can be dangerous.
Never mix vinegar and bleach. This creates toxic chlorine gas.
A vinegar/ammonia/baking soda solution makes a great tile grout cleaner. Fill a bucket with warm water and then add a half-cup each of vinegar, ammonia and baking soda. Stir the solution until everything is mixed well. Pour into a plastic spray bottle using a funnel, close the bottle and shake the contents well. You’re ready to clean.
Or you can try a hydrogen peroxide/baking soda paste. In a bowl, mix hydrogen peroxide and baking soda until it forms a thick paste.
Mixing oxygen bleach with water is another great way to clean tile grout. In a large bowl, mix equal parts water and commercial oxygen bleach, such as OxiClean®. Pour the contents into a plastic spray bottle using a funnel.
