Details of the cleaning procedure used on Addendum’s ropes. The gel was wrapped around the rope in a spiral (a), and cotton ties were used to mark cleaning site (b). The gel is very thin and transparent, enabling visual access to the rope underneath, and sticks perfectly to itself and the substrate (c). Upon removal, the side of the gel in contact with the rope surface appeared discoloured compared to the clearance gel, confirming that soiling had been absorbed into the gel structure (d). Cleaned area (e, to the right of the cotton tie) and an area yet to be cleaned (e, to the left of the cotton tie). Photos © Tate 2018
