How to Clean Tile Grout in 4 Steps!

Are those dirty grout lines staring back at you driving you nuts?! Then you need to try this grout cleaner from Home Depot to clean tile grout and keep it that way!

Follow these 4 steps on how to clean tile grout without breaking a sweat or vigorous scrubbing.

How to Clean Tile Grout

I have tried harsh cleaners and scrub brushes to clean tile grout, but they take a long time and smell terrible.

If you are looking to clean your floors, I did have good luck with soft scrub bleach and a toothbrush.

This will turn your grout super white, but the odor is very strong and this does not seal the grout.


If you decide to use soft scrub bleach, I recommend opening all the windows and wear a mask.

I recommend using an alternative that will not only clean your grout and turn it white, but seal it as well!

The Best Tile Grout Cleaner

As I mentioned before, I tried many different products to clean tile grout in my kitchen, but I didn’t get great results.

After trying several different products to clean tile grout, I found the best grout cleaner at Home Depot.

I recommend using Grout Renew to clean your dirty grout lines over other products.

This product will dramatically change the color of your stained grout with only a toothbrush and no scrubbing!

Grout Renew!

Step 1 – Clean Your Floor

Before you clean tile grout, sweep or vacuum your floor thoroughly then mop the entire area.

If you notice there are crumbs after moping the floor then I recommend vacuuming again.

I have 2 toddler boys that like to throw food all over the floor, so my floors are gross and require a couple passes of the vacuum to get them clean.

Step 2 – How to Clean Tile Grout

Now that your floors are squeaky clean, it is time to brighten up those grout lines.

First put on gloves then pour a small amount of Grout Renew onto a paper plate.

Start in a corner of the room with a soft bristle toothbrush, a rag, and your grout cleaner.

Lightly dab the toothbrush into the Grout Renew and brush it gently onto the grout line.

Dragging the toothbrush along the grout line until the brush is dry.

Then dip the toothbrush into Grout Renew again and continue to work your way around the room.

Repeat this process until your entire floor is complete. Be careful not to step directly onto the grout lines until the area is completely dry.

So, you might have to play hopscotch for several house until Grout Renew is dry. I recommend applying the Grout Renew before bedtime, so the floor can dry overnight without pets or kids walking on the floor.

Look at the difference already!

Step 3 – Optional 2nd Coat of Grout Renew

My floor looked great after one coat of Grout Renew, but in higher traffic areas the grout looked a bit gray not bright white.

So, in higher traffic areas, I recommend doing a second application as the grout may not be as white.

You might noticed after several months, the higher traffic areas look a little gray again. So, you might need to do a quick touch up occasionally.

After applying a second coat my grout lines turned out bright white and match my white cabinets perfectly!

After! Just need to mop to get rid of the haziness.

Step 4 – Cleaning the Floor

It is recommended to let Grout Renew dry for 72 hours or more before getting it wet.

So, let your floor completely dry before moping the floor again or you will risk removing the Grout Renew.

Your floor will look slightly hazy at first, but this goes away after you mop the floor.


After I finished my kitchen floors, I moved onto the bathroom and the grout line along the outside of the shower.

There are 2 things in my home that make me smile, bright white grout and clean paint lines along the ceiling.

Well I a clean kitchen makes me happy too, but I gave that up because I have two toddler boys.

I hope this post gave you the motivation to start cleaning your grout. Once you get started, you won’t be able to stop with this product.
