Tiles - cleaning?

Question:is there a tradesman that could come out and clean an area of 2.5mx0.5m of mosaic tiles to their original state they are covered in hardened wall tile adhesive which due to arthiritus i cannot remove due to the amount of scrubbing needed. i have used brick acid which has taken some of it off.

i would appreciate if someone could quote me on this unsual job - the house in Brogborough Bedford, MK43, UK - i require someone urgently - thanks

Sorry i can't come and do the job, unfortunately i live in Pontefract. The brick acid was a good idea, however you will find that a good descaler will work much better. This is what i have used in the past to remove old tile cement from a tile surface, and also to bring back the grout line to look like new. You need to use it with a scotchbright pad. Good luck.
