Original Idiotic Quarry Tiles Please Clean them for me

[Capital]

spent today scrubbing these tiles in my kitchen with Wickes tile renovator but cannot remove the bloomin blooming whiteyness from them. What is it WHAT can I do. Feel like farking cinderella, hand red and bloatey with effort.

Help?

It's probably salts coming through, scrubbing won't really help. You can try a product such as Effex to get rid of it and then seal them. Or there are specialist companies that restore tiled floors if they are in a really bad way. Do a bit of research to find out if the problem is salts (sometimes called efflorescence) and treat appropriately.

Thank you lala! Will do a little research as you suggest.
