Please can anyone suggest the best way to remove plasterboard adhesive from brick so that the brick still looks Ok. I've tried chipping it and sponging the rest with water , but now I have a general grey dusty tinge to the brick. Must be a better way?
This is for a conservatory, where the previous people stuck plasterboard on what was the external wall . I've removed the plasterboard but need the bricks to look nice. House is 10 year old red brick. Thanks
