I do wear gloves though
we have quite soft water so all i tend to do is mist the glass with my general-purpose orange spray and leave it a minute. When i've cleaned that i rinse down, dependant on dirt levels i use a cream cleaner on tiles and shower tray.
Manky grout i use bleach once the whole think is thoroughly cleaned and rinsed. Dont have to bleach often, usually when i first go to a house.
