One solution for cleaning tiles?

[Sprogginz]

Not sure if my question belongs here so apologies in advance if it doesn't.

I'm about to to try and improve a relatives bathroom such as tiling the surround for the toilet's plumbing and a bit of painting.

For the existing tiles there's a build up of limescale and somekind of orange scum that has especially built up behind some shelving. Is there a really good one-solution cleaner that will do everything from getting rid of all the crap to bleaching the grout nice and white again? This could be something I would have to make up myself.

Basically something that disolves everything in sight apart from the tiles & taps!

go to a tile shop and get yourself some HG Hagesan cleaner

They make different ones for different purposes and depending on tiles ,a quality product which actually does what it says ..................

Nothing will bleach you grout white again!!! not even bleach
