Schaeffer’s | Penetrating Oil | Penetro90

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 a patented formula of penetrating oils, synthetic isoparaffinic hydrocarbons, special friction releasing and extreme pressure additives, 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.
