How to clean the grout on the floor of my shower. I've tried everyth

We found the Turbo scrubber was the answer to ours. I just use my every day cleaner, but the Turbo Scrubber did it for me! We ordered ours online, but you can get them in Walmart now and probably other stores. It takes out the dirt and relieves the elbows of all the hard work.

I will try this, I have used pure bleach and still can not remove it.

Make a thick paste of baking soda and warm water. Dip a "hard bristled" toothbrush or a grout brush in the paste and work it into the grout. Let sit for 15 minutes. Fill a spray bottle with a solution of 2-to-1 white vinegar to warm water. Spray the area with vinegar-water solution. (The vinegar will cause the baking soda to bubble up and will start to work away that nasty soap scum. ) Use your brush and get all the way into the grout lines to remove buildup. Rinse very well. Consider sealing the grout lines.
