Dear colleagues, Does anyone have experience with the use of quaternary ammonium chloride on metals? Quaternary ammonium chloride is a chemical commonly used as disinfectant (both concentrated and diluted) : we will need to treat a large number of objects that have been possibly contaminated with bat guano. It’s a pretty strong chemical with a pH comprised between 11 and 12 and described as a strong oxidizer in the safety sheet. I didn’t found a lot of documentation, the most interesting study is: Greg McBride Effects of the Quaternary Ammonium Disinfectant Green Solutions High Dilution (1.8%) on Metals and Non-Metallic Materials used in Fire Operations, available online.
Does any of you have any experience on treating bat/rat/mouse contaminated metal objects (mainly brass)? What products have you used? Have you done any testing on Quaternary ammonium chloride? Thanks a lot, Emanuele EMANUELE MARCONI Conservator National Music Museum University of South Dakota ****** Unsubscribe by sending a message to consdistlist-le...@cool.conservation-us.org Searchable archives: http://cool.conservation-us.org/byform/mailing-lists/cdl/
