Can biocides harm archive and cultural assets?

Benedictus van Oudheusden, one of our employees, student at the FH Bern University of Applied Sciences//HKB Bern University of the Arts, Bachelor of Arts in conservation, has written a research paper on the following topic as part of his studies:

Does cold vapour atomisation with commercial mould destroying products have a detectable impact on archive and cultural assets?

On the basis of a series of experiments with different practical test objects and different biocides, he investigates whether the concentration of bleaching substances of the biocides is high enough to cause a bleaching effect on the paper. 

Research result
"Yes!" - There is a clearly noticeable bleaching effect of the paper. Based on this result, docusave feels highly confirmed in her standardized practice of using these products for cold vapour atomisation. docusave uses biocide-containing products to disinfect cleaned rooms. Before using cold vapour atomisation to disinfect a room, all books, documents or other organic material have to be removed to another location.

Important
Suitability and effectiveness of the products used in the experiment (one product based on hydrogen peroxide by Sanosil Ltd., a further commercially available disinfectant based on QAC) for the fight against mould respectively for the disinfection of rooms and surfaces are not questioned in any way, if properly applied. The purpose of this research paper is to show their suitability or unsuitability for the direct treatment of sensitive archive assets (or other organic products) because of their bleaching effect.
