How do I get the excess dirt in floor in bathroom ?

Do a deep clean of the grout. I used Lysol toilet bowl cleaner in the black squirt bottle. Once you get it clean, you can re seal it.

If that doesn't work, paint with an outdoor paint and then re seal it. I've done that as well. I had some white tile where my ex-husband used an off white grout and it looked bad. I painted it black and absolutely love it.

Clean the grout with Gel toilet bowl cleaner and a scrub brush. Then get some Mapei Grout Refresh/Restore. This stuff is wonderful. You can change the color of your grout if you wish and It has a sealer in it so no more worries about mold etc.

I used a steam cleaner on mine with grout cleaner and it worked wonders!

Do you mean clean the grout from dirt https://brendid.com/ultimate-guide-to-cleaning-grout-and-tile/

I use a steamer...works great.

Use grout paint. Paint the grout and as you do wipe off the edges of the tile with a damp rag. I did my shower several years ago and it still looks great. Sold where the tiles are sold.

Hi Sheri. Use a good brand of toilet bowl cleaner, a bucket of warm water, and an old toothbrush. That will clean your grout lines nice and clean. Good luck Sheri.

To clean the grout lines you will need to use a good cleaner, hot water and a scrub brush. One cleaned as good as you can, Let it dry well then apply a "grout Sealer" to the grout. This will help to keep the grout from absorbing dirt.
