Ghent’s Sparkleen is specially formulated to cut through built-up residue faster and easier than any other markerboard cleaner on the market. The non-flammable Sparkleen conditions the markerboard surface as it cleans and removes hidden ink particles from the surface, helping to restore the board to like-new condition. Sparkleen Markerboard Cleaner’s formula is so effective it even removes most permanent inks. ACMI certified (conforms to ASTM D-4236).
