Does anyone know of an approved-by-conservators method to clean salt stains off varnished historic wood floors? We've dug out from our 27" of snow that we got on Sunday and Monday (although it's snowing again now), and now we're dealing with salt being tracked on the floors. We have runners down to keep people off the wood floor, but some salt and melted snow manages to trickle over anyway. I've tried wiping the floor with a mixture of distilled water and .5% Photo-Flo 200 or .5% Tritan X-100, rinsing with distilled water and then drying with a clean cloth. This method didn't work. Thanks for your help. Anne Markham Museum Technician Edison National Historic Site West Orange, NJ (201) 736-0550 x26 FAX (201) 736-8496
