Things You'll Need
Instructions
Wet Cleaning
Test the ink on one small corner to make certain it is insoluble and will not run. Old inks are usually stable.
Clamp the stamp to a nonmetallic screen with a nonmetallic clamp.
Mix four drops of clear liquid soap into one pint of water. Make certain that there is no color in the soap. Immerse the clamped stamp slowly into this solution.
Press the water from the clean stamp on white blotter paper.
Place the stamp between two sheets of white blotter paper when all the moisture is removed.
Set a medium-weight book on top of the stamp and allow it to sit overnight.
Remove pencil marks by gentle rubbing with powdered pumice on a cotton swab. The paper may be too weak to handle this action without compromise.
Add alum to hot water to remove stains. Immerse the stamp into this solution and delicately rub the stain with a cotton swab. Rinse in clear water, blot and press.
Dry Cleaning
Place the stamp on white blotter paper.
Use a white pencil eraser to gently rub the stamp. Do not use vigorous motions in this erasing; in fact, be gentle so that the paper does not become compromised. Faber-Castell Magic-Rub #M-196 is a good eraser to use in this procedure. Be sure to keep a clean edge on the eraser.
Brush with a soft shaving brush to remove loose dust.
Sprinkle Draughtsman's cleaning powder over especially difficult dirt.
Use a circular motion and the soft brush to move the powder from the center of the dirty spot to the edges.
Use cotton balls instead of your fingers to handle the stamp and brush off the powder with the soft brush.
