Plug and Contact Cleaner Case 12.5 Ounces

The Plug and Contact Cleaner Case 12.5 Ounces by KLOTZ SYNTHETIC LUBRICANTS is an essential maintenance product for mechanics and automotive enthusiasts who demand reliable electrical system performance. Spark plug fouling, corroded battery terminals, and oxidized connector contacts create resistance that degrades ignition timing, fuel delivery precision, and overall engine efficiency—especially in high-performance builds where every thousandth of a volt matters. This specialized cleaner addresses those failure points directly, restoring clean metal-to-metal contact integrity that factory wiring harnesses and OEM connectors depend on for consistent operation.

Formulated with KLOTZ's proprietary synthetic base stock, this plug and contact cleaner dissolves carbon deposits, oxidation, and corrosion without attacking rubber gaskets or plastic connector housings—a critical distinction when working on modern wiring systems with integrated sensors and ECU inputs. The 12.5-ounce container provides sufficient volume for multiple cleaning cycles across an entire engine bay: plug wells, battery posts, alternator connections, fuel injector seals, and ignition coil boots. The thin viscosity allows deep penetration into corroded crevices, while the synthetic carrier evaporates cleanly, leaving only a protective residue that inhibits future oxidation without attracting dust or debris.

Serious engine builders, daily-driver modifiers, and professional shops rely on contact cleaners during maintenance. This product is compatible with various surfaces, including cast iron, aluminum, brass, copper, and rubber seals, making it versatile for different applications. Whether you're working on a performance engine or routine maintenance, this cleaner ensures optimal electrical connections and system reliability.
