Thank you Steve, Good luck with yours as well fella , thats one hell of a big fire place you have there.
Have you got any plans for it? We have decided to keep our inglenook as an open fire as it's in the dining room and just light it on special occasions, they do take some messing with though to get them to actually work.
Edit - a stiff tooth brush works well with cement away but remember to wear eye protection and gloves. Play around with the dilution to get something strong enough to do the job but not strong enough to do any damage.
