Jayne,
Great name. Granite, I say, don't be shy, blast away with a power washer.
Now let's here from the conservators.
Best,
Leland

Subject: [BP] Cleaning Polished Granite
Hi All,
I've been skulking around the perimeter of this listserv well over a year
now and
recognize I'm past due introducing myself.
I'm a project manager in Denver, currently working a corporate ebusiness
contract, which
could not be a further throw from the wonderful world of stone. Most other
times,
however, I'm easily found in two of our historic cemeteries.
Over the last few years, I've done monument conservation training with
NCPTT, received
my cert from Jahn to use their restoration mortars and generally spend my
time teaching
other volunteers stone assessment practices and cleaning, and doing small
repairs.
We've had success with several products from Prosoco (Biowash & 2010) on
stable but
soiled marble, limestone, and unpolished granite monuments. However, I
haven't had
any success cleaning polished granite. Most of the soiling is obvious black
layering which
is likely carbon based deposits from the many industrial stacks and
railroad/other vehicle
emissions so prevalent in the area.
Does anyone have thoughts on how to safely clean these polished granite
headstones and
monuments?
Many thanks,
Jayne Uhlir
