Description
Natural, controlled media for gentle surface preparation
Walnut shell blasting media is a natural, biodegradable micro-abrasive widely used for light cleaning, surface preparation, and controlled removal of conformal coatings from printed circuit boards (PCBs).
It provides a balanced combination of effectiveness and gentleness โ stronger than sodium bicarbonate, but significantly less aggressive than aluminium oxide โ making it well suited to sensitive electronics rework, refurbishment, and selective de-coating tasks.
Why choose walnut shell media?
- โ Natural and biodegradable โ environmentally friendly abrasive
- โ Low dusting โ cleaner workstation than many mineral abrasives
- โ Gentle on substrates โ reduces risk to solder mask and fine features
- โ Effective cleaning action โ removes residues, light coatings, and surface contamination
- โ Compatible with micro-abrasive systems such as Vaniman ProBlast
Typical applications
- Light removal of acrylic and urethane conformal coatings
- Surface preparation before inspection or rework
- Cleaning of solder joints, pads, and connector areas
- Selective de-coating for test point access
- General electronics refurbishment and cleaning
How it compares to other media
- Versus Sodium Bicarbonate: more effective removal with slightly higher abrasion
- Versus VanAcrylic: softer cutting action and slower on thick coatings
- Versus Aluminium Oxide: far gentler and safer for sensitive boards
Supply format
- Material: Crushed walnut shell (natural, biodegradable)
- Grade: 240 grit
- Pack sizes: 15 lb and 50 lb bags
- Use case: Micro-abrasive blasting for electronics

Recommended system for best results
Walnut shell performs best when paired with a dedicated micro-abrasive system and proper dust capture. For clean, controlled, and repeatable results we recommend the:
๐ Vaniman ProBlast 3 ESD Complete System (with StoneVac II)
- Stable ESD control for sensitive electronics
- Consistent airflow and media delivery
- HEPA dust capture for a cleaner workstation
- Turnkey setup โ unpack, connect, and start work
