Centrum eraser sponge for boards 120×35×50 mm (model 82067) is a rectangular cleaning sponge designed for dry-erase and chalk surfaces.

Advantages

The sponge combines a lightweight foam core with a dense outer texture that enables efficient, streak-free wiping of dry-erase markers and chalk residues. Its rectangular 120×35×50 mm format provides a stable grip and even contact with the board surface for consistent cleaning. The product is low-maintenance, requires no cleaning fluids for routine use and is easy to store between tasks.

• Cleaning whiteboards and dry-erase surfaces in classrooms and training rooms
• Removing chalk dust from chalkboards in schools and lecture halls
• Quick wipe-downs of smooth non-porous surfaces in offices and meeting rooms

How to use

Hold the sponge by its sides and apply light to moderate pressure while wiping across the board surface in a single direction or in small circular motions to remove marker ink and chalk dust.

If the sponge becomes saturated with residue, tap it gently to remove loose particles or rinse and air-dry according to material tolerance.
