Subject: Baking soda
The National Trust has been approached by a manufacturer to do a "demonstration" using their baking soda product to do general cleaning of interior and exterior surfaces at some of our historic sites. (This is a marketing department scheme that may unfortunately impact the museum operation.)The manufacturer would not be working on objects, but would be doing floors, window frames, doors, walls, etc. I am not sold on the idea, by any means, but am looking for some technical assistance. Can anyone help me as to whether or not this is a good idea or not, and why or why not? I know that in its dry state, baking soda can be mildly abrasive. However, if it is mixed in a water solution, does it still have that property? Any help would be appreciated, as I need to give an informed answer to the "powers-that-be" as to whether or not this is a viable activity for the Trust. Melissa M.
