What Is Hot Tank Cleaning?
Hot tank cleaning is a deep-cleaning process for engine components. Parts are submerged in a heated cleaning solution that lifts away the grease, oil, carbon buildup, sludge, and rust that ordinary cleaning can't touch. It's the kind of thorough cleaning that gets engine parts truly clean — down to bare metal — so they can be inspected, machined, and reassembled correctly.
Why Clean Parts Matter
Skipping a proper cleaning leads to problems down the road. Hot tank cleaning sets up everything that follows:
Accurate machining
You can't measure or machine a dirty surface correctly.
Proper sealing
Gaskets seal against clean metal, not grime.
Thorough inspection
Cracks and damage are only visible on clean parts.
A longer-lasting rebuild
No leftover debris circulating in your new engine.
What We Clean
We clean a wide range of engine components for cars, diesel engines, and motorcycles. For aluminum and specialty components, we'll use the cleaning method that's right for the part — just ask and we'll recommend the best approach.
