I did a shower/bathroom combo today that had massive smoke buildup from a fire. The tile cleaned up well, but it seems like there is still some mildew in the grout lines. I used Viper Venom, mixed heavy, and scrubbed my arse off before extracting with the SX7 tool at 1000 psi. This was a poorly maintaned bathroom to start with, and we're not there to clean their other messes (according to insurance adjuster.....this is an insurance job), but I would like to get it as clean as possible. There is some grout damage, but I don't repair grout. What's best for mildew, other than bleach???
