The duo of Clean Works and Power Works from Green Way Products by PolyPortables are super-concentrated all-purpose cleaners for cleaning plastics without harming the surface structure. Rather than using petroleum or alcohol-based surfactants, both use high micelle active plant-based surfactants to aggressively penetrate and lift hydrocarbon dirt and grime. Clean Works is suggested for general maintenance cleaning, and Power Works is suggested for tough-to-clean projects, including greasy dirt and grime. It is a solvent-enhanced heavy-duty cleaner and degreaser using soy methyl ester technology, a naturally less volatile and safe solvent for cleaning plastics and painted surfaces. Both come in fragranced or non-fragranced formulas and can be diluted up to a 175-1 ratio. They are environmentally safe and will not harm restrooms or technicians. 800/241-7951; www.polyportables.com.
