Acetone is a highly volatile material, used as a general purpose solvent and cleaner. Used for cleaning brushes and rollers after laminating.   Acetone should be stored in a sealed metal container and measured out in small quantities; say 2” [50mm] in the bottom of a plastic container in which you should thoroughly wash the brushes and tools. You can store brushes and rollers in clean acetone overnight, make sure you use a sealed container, as acetone has a high evaporation rate.
