Penetone has over 60 years of experience in solving maintenance and production cleaning problems in steel and aluminum mills. We understand that steel and aluminum production has its own unique cleaning needs. The removal of hazardous oil accumulations and spills on floors and production equipment. The need to remove carbon, soot, grease and oil from machine parts. The necessity to control fugitive dust throughout the plant from slag pits to coil fields. We have a complete family of products developed just for the special needs in steel and aluminum mills. Environmentally safer, highly effective products that make economic sense.
