Cleaning up ceramics

[Flintstone]

Can anyone advice the best thing to clean up some white ceramics, in a shower, it's a re grout and general clean up, there a bit grimey. A lithofin product?

General greases and grimes, intensive cleaner first 1-3 white pad, 10-15 min
if salts remain on the surface if a textured tile ,I follow this with ceramic clean 1-1 .
test all on a single tile .
