Good Evening. I recently laid a really nice porcelain floor in my new basement washroom. In my haste, I did not fully clean the grout off the surface of the tiles, and had not had time to go back to it for several days. This tile is not smooth and the grout has managed to lodge itslef firmly into it and now I can't begin to imagine how I'm ever going to get it out. We've searched online to find solutions, but I'd like to hear some true testimonials from others who've done it for real before and can tell me about it.

Thankfully most of the bathroom is OK since I was more careful after the initial part (washer and dryer section) was done, but I'd still really like to get that cleaned and I could use some ideas .
