AbstractAqueous cleaning of ancient paper samples is a common treatment for the removal of degradation products,
external contaminants and salts, which can cause degradation of cellulose by hydrolysis or oxidation
processes. The present study examined the influence of selected cleaning treatments on chemical properties
of some historical paper samples and studying the efficieny of cleaning methods in removing of degradation
products .It also investgated The effects of five different cleaning treatments, namely immersion in deionized
water, akapad paper sponge, hydro gellan gum, Cellulose nano Crystal gel and cleaning with wolbers solvent
gels on ancient cellulosic paper supports. In particular, the effect of the cleaning treatments on different
properties of cellulosic paper supports, namely colorimetric properties (CIE L*a*b* coordinates), crystallinity
index (X-Ray diffraction) Fourier transform infrared spectroscopy(FTIR), scanning electron microscopy
(SEM) and pH (cold-extraction method), were investigated. The study concluded that all cleaning treatments
affected the colorimetric properties of the selected paper samples.
