HR 3D scans of 5.3 × 5.3 mm of an (A) aged beeswax coated (WX) and (B) uncoated plaster (uc) plate: (i) without soils, (ii) with soils and (iii) after the cleaning trial of 1 min contact with the PE-PAM₁₅ loaded with 70% v/v IMS in DI water. The maps at the right demonstrate that the SAG system tend to restore the surface roughness of the plates that had been increased due to the soiling deposits
