My husband grouted porcelain tiles but didn't remove it. Now its gone hard. How can I remove it?

Please help they cost alot of money

Try using some emulsifying pads initially ( scouring pads, fine grade not course) and lots of elbow grease. Mind the skin on your fingers as it will take that off too so wear rubber gloves. When you have got off as much as you can, try removing the rest with something like Lithofin Cement Residue remover, or Cement Away.

How long was the grout left on?

PS Welcome to the forums Louise.

If I where you Louise I would get cement residue remover, give it to the husband and let him sort it!
Expensive tiles need a good fixer to tile them properly, you may as well ahve bought B&Q specials!

And what grout was it..?..flexible etc.........and also how long was it left...?
