So the answer to the titular question is vinegar. Vinegar is better for cleaning. But that's because bleach isn't intended for cleaning, but for disinfecting.

Little did you know that cola is great for cleaning tile grout! If you have dirty, dingy grout, pour a bit of cola onto the area, let it sit for a few minutes, and wipe clean.

Grout that hasn't been sealed, needs to be resealed, or is in poor shape should not be cleaned with vinegar. The vinegar penetrates into the pores of the grout, further weakening the material. Over time, vinegar will deteriorate the condition of the grout by etching or wearing it away.
