Folks:

Anyone out there know of "Magnus Granite Cleaner?"  It was specified  
in 1934 for cleaning a granite war memorial that I'm involved with.   
The archival documentation mentions the product & advises the strength  
of solution(1 lb cleaner/gallon water) & that it be mixed in a wooden  
bucket not metal & be applied to dry stone & then rinsed with clean  
water.  Just curious :).  Thanks.
