Cleaning your engine improves your car’s performance, giving your ride a smooth hum and helping critical components operate at optimal temperatures.

How To Use Engine Degreaser

Degreasing your engine bay is easier than most people think. Here are the basic steps for safe and effective engine cleaning:

1. Let the Engine Cool: Never apply a degreaser to a hot engine.
2. Cover Sensitive Parts: Protect the battery, alternator, air intake, and electrical connectors with plastic.
3. Shake and Spray: Use a proven engine degreaser, like Berryman® B-33 Engine Degreaser. Shake it well before use, and then spray directly onto greasy engine parts.
4. Let It Soak: Wait 10 to 15 minutes for the product to break down the grime.
5. Rinse Carefully: Use a light stream of water to rinse everything off. Avoid pressure washers near wiring or sensors.
