Schaeffer's 0190-011-1 Penetro 90® Lubricating and Penetrating Oil

Penetro 90^® is a high-performance penetrating oil that lubricates all types of moving parts that have become difficult to operate. Penetro 90^® is oil based and blended from our patented formula of penetrating oils and three different types of rust and corrosion inhibitors. This unique blend allows Penetro 90^® to penetrate deep into the pores of metals, and cover surfaces with a light, clear lubricating film with lasting staying power. When sprayed onto rusty bolts, Penetro 90^® coats each rust particle and acts like tiny ball bearings, allowing the rust particles to easily slide over each other.
