...is it the same as brick cleaner? I've got brick cleaner already and notice that for the price of 1litre of grout cleaner is about the same as 5L of brick cleaner.

Domestos and a sponge works for me.
Brick acid (if that's what you have) is very strong (upto concentrated,
30%) HCl. You would not want to use that on grout. Citric or formic acid is about as strong as I'd go.If the grout is _really_ manky, then THIS stuff is the dog's...
I've used this stuff:
which seems to work OK. Although I suspect anything with bleach as an active ingredient will work.
Spray it on and, if you're feeling energetic, work it into the grout with a toothbrush. Just make sure it isn't your toothbrush.
Brick cleaner is acid ... grout cleaner usually alkali .... polar opposites

FWIW I have some "LTP Grout Stain Remover" which says "Contains hydrochloric acid < 10%". I've not used it myself but it was left by a plumber who used it on our shower (limestone) and it seemed to work well. One of the reasons I've not used it (yet) is that the label specifically warns against using it on limestone.
HCl will reomove chrome plating as well.
Not used that, but their mould remover is the puppys parts.
The label is right! Don't do that - or on marble either....
The interesting thing to me is that I'm pretty sure the plumber (who has specialised in fitting limestone bathrooms for at least ten years) *did* use it, leaving a sparkling shower area with no apparent ill-effects. He left me the 1-litre bottle, about 2/3 empty, saying it was a doddle to use.
The bottle advises diluting it 4:1 for normal staining, so we're a long way below the 30% of brick acid.
Yet _another_ one for ahbou. :-)
I fear I have been misleading everyone! The grout isn't dirty. The grout is the dirt. Newly grouted new tiles have residual grout on the surface. Tiles are slightly textured so the usual buffing off needs some help.

+1 for both. I bought them in Homebase. Just spray on, leave for an hour or so, reapply then rinse off with a garden spray filled with warm water. Might need to use a plastic kitchen scourer on really manky parts.
Take me about 2 hours and I do it once a year.
Ahhhh, now it makes sense, in this case the answer is:
ANGLE GRINDER :)
I use the wifes. Well, it also does a good job of the toilet bowl.
