Graffiti removing compsn. based on methylene chloride - and contg. alcohol and ketone solvents, frosting agent and water, applicable to various surfaces

摘要

A compsn. for removing graffiti comprises (a) 74-93.5% CH2Cl2; (b) 5-20% of an alcohol e.g. MeOH, (c) 5-20% of a ketone solvent e.g. acetone, (d) 1.5-5% of a frosting agent and (e) less than 1% water. The compsn. is dispersed as an aerosol. Used for removing graffiti from materials such as concrete, brick, cement, stone, marble, paper, fabric and the like. The compsn. is sprayed onto the surface, allowed to rest for a few minutes, brushed and then rinsed. To remove graffiti from a painted surface, the compsn. is sprayed on a wet surface, e.g. a sponge or rag and the painted surface is rubbed with the sponge or rag.
