The document discusses techniques for restoring paper, including washing by immersion, float washing, and blotter washing. These techniques involve spraying or placing the paper in trays of water and organic solvent mixtures to clean it. The paper is then removed carefully and allowed to dry using blotters, felts or cotton swabs. Common materials used include water, wetting agents, enzymes, and alkaline solutions.

Washing by immersion: In this technique, the paper is sprayed with a
water/organic solvent mixture and placed in a tray, which will be then filled
with distilled water and prepared with chlorine. Finally the paper will be
removed carefully from the tray and will dry with blotters, felts and cotton
swabs.
Float washing: This technique follows the same steps as above, but in this
case, the paper is placed on a screen that floats on water.
Blotter washing: The first steps are the same as in the other two techniques,
but here the paper is placed on a moistened blotter, and then is introduced
in a tray.
