https://www.diynetwork.com/how-to/maintenance-and-repair/cleaning/how-to-clean-grout Have a good day!

I use a toothbrush and hot water, it works well for me. Mopping leaves the residue in the grout lines and then the dust and dirt residual will dry in the grout and discolor them if they aren't rinsed really well.

If you can't get the grout to where you want it, after cleaning there are products you can use to change the color. Grout Renew or another grout stain will make it look better. Even though some of them have a sealer, make sure to seal it again. It helps to make it easier to keep clean.

Toothbrush and bleach!

Thank you very much
