It's really not hard.
Warning, bleach is a pretty strong chemical, and it can burn you skin, eyes, and throat. The fumes can make you pass out if you are not careful, so work in a well ventilated area to prevent this. It is also recommended that you wear gloves, although I don't because my skin is used to the bleach.

As many have stated, there are other types of cleaners, bleach is just my preferred method. Some other choices are the following:
Hydrogen Peroxide mixture
White vinegar mixture
Regular cleaning is also a good way to prevent mold, mildew and other discoloration of grout and tiles.

If you get bleach on your hands and get that 'slimey' feel where you can't get your hands squeeky clean, a simple solution is to apply rubbing alcohol to your hands, and then rinse. It strips the bleach residue off.
I'm now weary of using cleaning chemicals but what else would help clean grout that hasn't been attended to by a "maid" for several decades?
It's winter now and I'm stuck: the grout needs weekly cleaning and to open the windows would mean heating bill will go up a % this time last year.
I open the window whenever I shower, summer or winter.
My shower has three sliding doors.
When done I always leave the two end doors open 6" to 8" so the moisture can evaporate.
There is, after a period of time, a small build up of mold on the grout. I use a spray bottle of 100% (Not diluted) chlorine bleach. I set the sprayer for "stream" rather than "spray".
I leave the window open and the bathroom door closed for several hours until the odour is gone.
