Abstract The study evaluates and examines novel eco-friendly methods and materials to be used in surface cleaning photographs, assessing their impact on their optical, mechanical, and chemical properties. The selected materials and methods are Hibiscus Sabdariffa L. Calyces’ aqueous extract, DBD Argon plasma and ethyl lactate. The Hibiscus Sabdariffa L. Calyces’ extract as a contact method and argon DBD plasma as a non-contact method were examined to clean fire-damaged silver gelatin prints’ surface. The Hibiscus Sabdariffa L. Calyces’ aqueous extract proved efficient cleaning to the firedamaged silver gelatin prints’ surface without causing any harm to the photographs. On the other hand, plasma with the absolute aqueous extract proved to be less effective in cleaning, leaving a light residue of soot and made gelatin more susceptible to deterioration. Three concentrations of ethyl lactate were examined as well to remove different types of stains (i.e., adhesive stains and smudge stains) from (DOP) silver gelatin prints’ surface. The three concentrations proved theirsuccess in cleaning silver gelatin prints’ surfaces from different stains without causing any harm to the structure or the properties of the print (i.e., optical, chemical, and mechanical). The assessment methods to detect the damage and cleaning effectiveness were; Digital microscope, spectrophotometer, pH measurements, Atomic Force Microscope (AFM), Attenuated total Reflection-Fourier transform infrared (ATR-FTIR) and mechanical properties (Tensile strength and elongation). |
