Before I add my two-bits worth to the discussion, I gues I should introduce
myself.
I am a mature student who returned to complete a BA started over 30 years
ago. I am studying Art History with a focus on heritage architecture. I was
the President of our local heritage preservation organization and am now
the part-time office manager. About a year and a half ago, I was elected a
Director of the Heritage Society of British Columbia, so now I have input
at the provincial level. Next spring, I am doing a directed studies on
heritage preservation in Victoria, B.C. over the last 25 years.
Speaking of cleaning stone, I was asked to witness what seemed truly
remarkable to me. A local firm uses biodegradable chemicals mixed with
water to remove all the grime from sandstone and other types as well. The
contrast between the unclean and the clean is amazing. I do not know the
cost, but it must be cheaper than the methods I had heard of before - this
includes scrubbing by hand (which would take forever, me thinks). This
solution was applied, left for 5 to 10 minutes to work, then lightly
brushed and rinsed with clean water.
Unfortunately, the building in question, an old church (100 years old - old
for this part of the world) has been bought by the local Music Conservatory
and they have limited funds so the cleaning will not be done.
I am enjoying the postings - glad to find people who think as I do.
