The grout can be scrubbed with friction by using the grit of baking soda. In the process, the detergent is able to remove dirt and oil.

Scrub the grout continuously until it appears new. Once you’ve finished cleaning the grout in one area, grab a sponge, and scrub off any grime or dirt. The sponge should be rinsed frequently so that you are not only moving the dirt and dirt across. This gives your grout that like-new look. ovdnksn8rj.
