Gaussian curve-fitting of the ester peak of Clear Aligner before (CO) and after treatments with Retainer Brite (RB), Retainer Cleaner (RC) and Steraligner (ST) cleaners. The additional peak after ST cleaner at 1669 cm−1 of Fig. 2 is analyzed in two peaks at 1678 cm−1 and 1664 indicating formation of acid derivatives (1800–1650 cm−1 range, absorbance scale, dotted lines: original spectra, r2: coefficient of determination for the goodness of curve-fit)
