SMOKE SPONGE vulcanised rubber, large size
The porous vulcanised rubber Smoke Sponge is a non-toxic dry sponge for cleaning off smoke and soot residue and general dust from books and paper. Cut into smaller pieces to use; move very gently across the surface, from the page centre outwards so as not to catch the page edges. When the sponge piece is fully dirty, trim it with scissors for a fresh area – don’t wash, as this affects the rubber and the effectiveness.
This is the largest size available, 6" x 3" x 1 1/2" thick.
