There’s no doubt that vinegar is a powerful cleaning agent. But does that mean it’s a good choice for cleaning grout? In this post, we’ll take a look at the pros and cons of using vinegar to clean grout and offer some tips for getting your grout looking its best. Read on!

What is grout, and why should we clean it?
Before we get into the specifics of using vinegar to clean grout, let’s take a quick look at what grout is and why it needs to be cleaned. Grout is a cement-based porous material used to fill the spaces between tiles in flooring and wall tile installations.
Over time, grout can become stained and dirty, making your tile installation look less than stellar. Cleaning grout is essential for keeping your tile installation looking its best.
Grout can also be damaged if exposed to harsh cleaning products or chemicals, like bleach and hydrochloric (muriatic) acid. This is one of the reasons that vinegar (which is acidic) is not always recommended to use on grout. But don’t stop reading yet – there are still some good reasons to use vinegar to clean grout!
Why might you choose to clean your grout with vinegar?
Despite the fact that vinegar is not recommended to use on grout, there are some reasons why you might choose to clean your grout with vinegar:
1. You’re trying to remove grout stains or mildew that occurs when the grout becomes dirty and wet.
2. You don’t have any other cleaning products on hand, and you’re looking for a DIY solution.
3. You want to try a natural cleaning method before resorting to harsh chemicals.
4. You want to save money, and vinegar is less expensive than other grout cleaning methods and products.
