Gallery and Storage Maintenance Technician Hilary Wang is removing green biogrowth from the Meudon Monument at the Rodin Museum. She uses small bursts of hot pressurized steam to carefully clean the porous limestone and a cotton rag to absorb the soiled run-off. Removing the biogrowth seasonally prevents it from becoming a large problem down the road. #behindthescenes #RodinMuseum #Rodin100
