cleaning textured tiles

[997.1]

Light coloured floor tiles seemed such a great idea at the time!

Alas, they are textured as well as light so they are accumulating dirt that needs to be deep cleaned. We have them across most of our ground floor. Maybe 100sqm in all. Maybe a bit more

Best way to clean? Bearing in mind it is a large space and I will be doing the cleaning myself, what's the best way? I would be happy to spend a day doing this once a year

Thoughts?

I live in Spain and have around 170m of outside porcelain tiles. A couple of times a year I mop the tiles with normal floor tile cleaner, with some agua fuerte (brick acid) in the water. I use around a cup full in a mop bucket. They come up like new.

Some kind of steam cleaner (not a fridge size one) ??
