Cleaning Grout off tiles

[housemover]

Can anyone help with a solution that will clean off grout/adhesive from tiles. I have recently tiled my kitchen and used the grout/adhesive mix, the tiles are black and are not gloss. Obvioulsy i wiped the grout as i went along but now the tiles look 'cloudy' and really need cleaning somehow. Have tried various cleaning products to no avail. Does anyone know of anything stronger to clean off the dried grout? Thanks

This stuff works. You should be able to find it locally without resorting to mail-order. Try a tile specialist.

a dry cloth and lots of elbow grease.

Cement is very hard. You need something that dissolves the cement surface film. Using just elbow grease takes a heck of a lot of time up.
