In a recent volume of the Journal of Architectural Conservation, there is re=
ference (in an article on Ely Cathedral) to the "Jos cleaning system", which=
 is said to be quick and effective at removing black sulphates from limeston=
e.  Can anyone give more information about this method, decribe the techniqu=
e, or give references to it ?

Thanks
