Hi, I have a marble fire surround and have had some work done recently
on the chimney flue. The plumber stuck gaffer tape on the marble to
hold some polyethene on, although he removed the tape when finished
there is still glue residue on the marble. Whats best to remove this
please?

There is only one tool for the job - angle grinder
