One year after install and never done more than a weekly spray of Lysol and rinse.
no scrubbing at all.
I have epoxy grout and porcelain tile in my shower and with a good fan left on a half hour timer after my shower I have never had to scrub my grout after a year of praying once per week with a disinfectant and rinsing after ten minutes it looks as clean as when it was first installed.
