Now, the real question is do you want to put in the time and effort of cleaning your grout the old-fashioned way, or do you want to breeze through your grout cleaning?

Cleaning grout and tile FAQ

Why does the grout in my bathroom always have more build-up or staining?

The biggest culprit for grout discoloration is mold and mildew, which can thrive on wet grout. You want to make sure that your grout stays as dry as possible, especially in your bathroom! You will want to create a daily routine to ensure that your bathroom grout is as dry as possible.

  • Run the bathroom vent after showering.

  • Squeegee your shower walls.

  • Wash any rugs or towels that are consistently touching a tiled area regularly.


  • Spray your shower grout with a 1:1 vinegar and water solution. Vinegar has a drying effect and also kills bacteria. If your grout is not sealed or needs to be resealed, hold off on using a vinegar solution so you do not damage your grout.

What is a good maintenance routine for tile floor grout?

Sweep or vacuum your floor daily, mop weekly, and clean your grout regularly. For high-traffic areas, you will want to clean your grout 1-2 times per month, but for low-traffic areas, you may only need to clean them 2-3 times per year.

For your weekly mop solution, you will want to make sure to use a pH-neutral cleaning solution.

Can I use bleach to clean my white grout?

Bleach should never be used to clean your grout, even white grout! Using bleach will actually erode your grout over time and can leave behind a film on the surface, which attracts more dirt and grim!


Phew! That was a long one, but a very much needed step by step. Now I know after that, our knees and arms are probably hurting, but man does our tile and bathroom look good! Here's the thing, this isn't something that needs to be done every week, but maybe every three months, would be a good idea. In the meantime, keeping your tile surfaces dry, washing rugs because they tend to get damp and dirty, and doing a weekly wipe-down, will put off this task for a much longer period of time.
