1. POPART – Cleaning research procedure
Cleaning techniques:
Mechanical (cleaning materials)
Aqueous cleaning agents
Solvent cleaning agents
Evaluation:
Stability (ability to induce changes =“least damaging”)
Effectiveness at removing soiling
Cellulose acetate (CA) pristine uncoloured transparent test sample
Techniques to evaluate changes:
Visual observation
Microscopy
Contact angle measurements
Gloss measurements
