"Cleanliness is next to godliness." With that said, grout stains usually look gross, and they can be as well the result of mildew, mold, and other substances you do not want in your house. Unfortunately, grout is not something we notice until it becomes filthy, dark, and dingy. Luckily, with the best grout cleaner, you can restore its former glory.

Cleaning grout can be labor-intensive and time-consuming, but it will never be the same when you invest in the best-rate grout cleaners. This article will guide you and offer you tips and recommendations for deciding on the right grout cleaner to use. But before that,

Why Do You Need Grout Cleaners?

Grout is basically a mixture of water, sand, and cement and serves as a space-filler connecting sections of filling voids, pre-cast concrete, and sealing joints like those between tiles. However, since it is slightly porous, soap scum, dust, and dirty water can coat it and even soak it into it over a long period, especially if it isn't properly sealed. Moreover, this dirty, moist environment usually offers the ideal foothold for mold and mildew to take root.

Therefore, with grout cleaners, you can remove even the stubborn dirt and stains that detergents can't. Also, you will protect your tiles and grout from future stains. Besides being a less expensive grout cleaning solution, it's less time-consuming and less labor-intensive.

With that in mind, let's check out the best-rated grout cleaner products on the market. Read on!

What are the Factors to Consider When Buying the Best Grout Cleaner Products?

1. Cleaning power

When shopping for the best grout cleaners, the most vital thing you want from these cleaners is to clean grout. So, the cleaner should be soft to polish your grout tiles without scratching them but sturdy enough to get rid of grout discoloration because of dirt, mold, and mildew. However, how strong of a grout cleaner you need highly depends on how dirty your grout is. A milder cleaner is fine if you're looking forward to preventing gunk from building up on your tiles and grout.

2. Active ingredients

When looking for the best grout cleaner, we recommend you counter-check the active ingredients so that you can have an effective cleaning. Then grout cleaners should be strong to clean soap scum, erase mold, lift dirt and brighten your tiles with ease.

Whitening and brightening: Although chlorine bleach is occasionally a go-to ingredient in whitening products, in this case, it's not necessarily the best option. Bleach is usually associated with some health concerns, for instance, respiratory damage, and it can release harmful airborne substances when mixed with other cleaning products.

However, you can still use it in small doses. We, however, recommend you looking for products containing feldspar. This naturally occurring mineral is usually crushed into a fine powder, which works great on hard surfaces, including tile and grout.

Mold and mildew removal: You will want a cleaner depending on your mold situation. So, here are some ingredients that believe in removing mold and mildew removal. Hydrogen peroxide, an acid, or chlorine bleach. For instance, a mild acid-based grout cleaner with citric or oxalic acid is the least harsh of these cleaning formulas and won't damage stainless steel, chrome, or tile. On the other hand, an oxygen bleach-containing hydrogen peroxide is relatively strong.

Moreover, chlorine bleach is considered the strongest and most caustic. However, it's important to note that bleaching formulas should only be used if you want to whiten your grout tiles, as they can also lift color from colored grout or stained grout. Besides, all these ingredients will successfully kill bacteria and germs, which, when used in low doses, can be handy, especially in kitchen and bathroom areas.

3. Healthy safety

Before using your best grout cleaner, it is wise to read the product's label. Some grout cleaners usually come with safety warnings and outlined the necessary steps to protect yourself. However, others don't include this information. If the information isn't included, check out the ingredients to see if they are dangerous or read through reviews to see precautions taken by other users.

Ammonia and chlorine bleach can be poisonous and caustic if wrongly used. In addition, both chemicals can cause eye and skin irritation and even respiratory damage. However, their grout-whitening powers are usually daunting, especially where stubborn grout stains, mildew, and mold are concerned.

Conversely, high levels of phosphates have been associated with irritation in humans and negative effects on water systems and aquatic life. Nonetheless, they're also handy in cutting through soap scum, softening water, and enhancing cleaning grout product's efficiency. Meanwhile, the U.S has been increasing phosphate regulations since the 1960s, removing this additive from most cleaning products and detergents, although not all.

For grout cleaners that include acidic ingredients, we recommend you use protective gloves and a respirator. For other pH-neutral ingredients, these safety precautions might not be necessary though it depends on individuals.

4. Application method

There are usually two ways to apply the grout cleaner: scour with a brush or spray and wipe. Scrubbing with a brush and the cleaner need a little work; however, this method can be very effective on heavily soiled grout and floors. For cleaning tools, you can use a toothbrush on small grout lines. A scrub pad or brush is best for backsplashes and floors. Some brands offer both the liquid cleaner and a broom head or scrubbing tool. We recommend you use gentle pressure and avoid forceful scrubbing to prevent scratching the surrounding tiles.

Conversely, spray-on products usually claim to work without scrubbing, which saves time and energy. However, these cleaners might have solvents, harsher acids, or chlorine bleach. So, it is wise to weigh the benefits of saving your elbow grease or potentially releasing toxins particles into the home environment.

6 Simple Rules to Follow When Using Grout Cleaners

It's important to consider your health safety and the safety of other people in the house before using the grout cleaner. Follow these simple steps if you're using the cleaner for the first time for optimum results.

1. Carefully read through the instructions of the cleaner before use

2. Always ensure you wear a respirator, protective clothing like gloves and goggles

3. Avoid scrubbing the tile cleaner vigorously into the grout since it might dislodge the actual grout.'

4. Use a small toothbrush or a grout brush to clean any tight spaces

5. Rinse the cleaned area carefully, using a shower head, for instance

6. Repeat the cleaning process treatment if need be.

First, allow the grout cleaner to "soak" into your dirty grout for about 15 to 20 minutes. Giving the grout cleaner more "dwell time" allows it to brighten, eventually whitening the grout. You can then wipe the grout clean.

2. How do you clean dirty grout lines between floor tiles?

Apply grout cleaner on the grout lines and allow it to stay there for 5 to 10 minutes, then get a toothbrush and scrub.
