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).
