BioBlend PO is an excellent penetrating oil and general purpose lubricant that is formulated from readily biodegradable renewable resource base stocks and additives. BioBlend PO has superior wetting ability and a high affinity for metal surfaces which offers excellent penetrating and loosening of frozen, rusted or stuck components. The green solvents used are excellent for dissolving dirt, grease and removing debris, while leaving a light lubricating film which helps control corrosion. Since it contains natural and biodegradable ingredients, it is safer for the environment. As with any solvent-type product, care should be taken when using around certain plastics, foam rubbers, urethanes, and painted surfaces as they can be incompatible.
