Peter Greven Active Pearls is an industrial strength hand cleaner specially formulated to remove grease, oil, metallic dust, graphite and soot. Boasting excellent skin compatibility, Active Pearls are made of dirt-binding wax pearls that are less stressing to skin than conventional scrubbing agents. The innovative dirt-removing agent, Active Soft Pearls (ASP), supports the cleansing effect of the surfactant combination through their lipophilic surface structure which adheres to greasy dirt particles and is dermatologically tested and proven. Recommended where frequent hand washing is required. Solvent, soap and fragrance-free!
