Crepe Erasers are generally the best material for removing adhesive residue left behind when removing pressure sensitive tapes, like sellotape (a must for paper conservators).
The eraser is an off-white colour to show any adhesive or surface dirt removed. They take their name due to the crinkled surface which aids the mechanical cleaning action.
These erasers have numerous uses, such as:
Cleaning old tape adhesive residues from the surface of paper, wood and other media, easily removing excess rubber cement, masking fluids and other adhesives.
Can also be used for cleaning marks from leather and suede.
