Hello all, this is my first time onto the forum and was hoping to benefit from your expert tiling advice for a problem which is causing me great frustration when I should be enjoying our bathroom in my pregnant state! 
My fitter has laid slate tiles in our bathroom. Despite urging him to pre seal them prior to fitting (Topps tiles recommendation) and grouting them he informed me this was needed. On returning from a short break, he had cleaned the tiles and sealed them, however, a cloudy residue remains on the tiles and evidence of grout remains on ridges of the tiles. It also seems the tiles have not been sealed properly as water stains remain on the tiles when spilled.
The products used to clean and seal the tiles were FILA- I have tried contacting them to no avail.
Q's are as follows:
My understanding is that I need to 'unseal the tiles' so I can scrub the grout (grout/cloud does not appear to come off now sealed). What products do you suggest I use?
What is the best way to scrub at the tiles once unsealed in order not to cause damage to tiles?
Finally, how do I go about sealing the tiles properly once thoroughly cleaned?
Your advice would be much appreciated!
