Frequently Asked Questions
What is dry walnut shell used for?
Dry walnut shell is commonly used as a soft abrasive in turbocharger cleaning. It removes carbon deposits, oil, and dirt from turbocharger components without damaging the metal surface, making it ideal for routine maintenance and overhaul operations.
Can walnut shell media be reused?
Walnut shell media can be reused several times, depending on the application and cleaning conditions. For turbocharger cleaning, it is typically used once or twice before replacement because the media becomes saturated with oil and carbon residues.
How do I store dry walnut shell media?
Store dry walnut shell in a cool, dry area away from humidity. Keep the bags sealed to prevent moisture absorption, which can affect blasting performance. Proper storage extends the shelf life indefinitely.
Is walnut shell abrasive safe on all turbocharger parts?
Yes. Walnut shell is considered a very mild abrasive (hardness 3–4 on Mohs scale). It is safe on most turbocharger materials, including aluminum, steel, and stainless steel, when used with correct blasting pressure.
