Stone cleaner

A (recently developed?) proprietary latex-based stone cleaner is
being used in St Paul's Cathedral, London. Since the conservator is
unforthcoming with any information about the manufacturer, I have
thus far been unable to track down the product. It is Belgian,
supplied as a paste which is brushed on, and some standard
'additives' (such as EDTA) are also available. The name and address
of the manufacturer, and any other information, would be much
appreciated.
