About Grout

Grout is a very essential fluid to seal the gaps on floors or so. However, if it’s not used properly in the joint areas of your tiles, it’ll get pretty ugly in the future.

You see, grout is basically a mixture of water, cement, and sand. Do you see the white or brown thing in between your tile joints? That’s the grout. 

However, grout is a thin layer and most of the time it can get uprooted by force. If you already have unsealed grout, you might have noticed the stain and dirt that piles up in that place.

Just like you, nobody likes their walls or floors dirty. 

Nevertheless, it can be a real headache for you. Because it’ll make your floor look gross and grimy.

So, here are things that you’ll need to start your cleaning:

How You’ll Clean 

The cleaning will be worth it if you do it right. However, as we said before, it’ll take some time and effort of yours 

However, we organized some steps that you’ll need to follow sequentially if you want your floor clean in no time. 

So, let’s get into the details.

Step 1: Clean the Surface

First thing’s first. You’ll have to check the area to see if any scattered pieces are remaining there or not. Moreover, you should see if you can remove it or not.

You should remove the scattered pieces and clean the surface thoroughly. Well, give it some time. You must let the grout dry fully. You certainly don’t want any tacky stuff there.

Step 2: Mix the Bleach Solution

Solution. Does it sound like chemistry to you?

Well, let me assure you, it’s nothing complicated. However, this indeed is the basic chemistry. 

You’ll have to take 2 tablespoons of the oxygenated bleach. Then, you need to dissolve it in 2 cups of your warm water. That’ll help you to clean the dirt now. 

You see, sodium percarbonate or oxygenated bleach basically reacts with the water. It releases oxygen when it reacts with the water and works effectively as one type of mold cleaner.

Sounds easy now, right? Because it is easy.

Now, you need to make the grout brush wet in that solution or mixture. Then, you should apply it to the grout.

Next, you’ll have to give it some time to soak in. After it’s soaked, you should scrub the grout in a circular motion. 

You might be wondering, why in circular motion? You see, it’ll loosen the stain more effectively than the back and forth motion. Also, it’ll help you clear the area faster when you go circular in motion.

On another note, you might need to dip the wet brush into the bleach to make a paste. However, you’ll need it when the dirt is in-depth. In that case, you should wipe the brush clean later on and let it dry.

Step 3: Use A Cleaning Solution

Does the area look clean to you? If so, you’ll need to seal it off now. Well, if not, you’ll need to come back to it again and it won’t be pretty. 

Also, you might even need to use a floor steamer. You just slowly need to work it across the tile floor and clean the floor in case of any dirt.
