Leland,

Did some tests w/ Minerva on travertine. Watched a large JOS project. The
street gossip was that sealing the windows was a real pain & people in the
building were feeling claustrophobic. Suggest doing mock-ups to make sure it
is the appropriate cleaning method to your needs. The end product looked real
good. Have had some experience w/ baking soda when it was being first
developed. Mostly familiar, and experienced in aggregate blasting w/ plastic
or walnut shells. Michael Davidson often manages projects for Thomann-Hanry.
What do you need to know?
