Organic abrasive made from walnut shells – Blasting Grade (eco-friendly surface cleaning)
Walnut shell blasting media is a natural, eco-friendly abrasive produced from crushed walnut shells for gentle surface cleaning and precision blasting.
It helps remove contaminants while preserving sensitive substrates.
With moderate hardness and an irregular, angular grain shape, this organic shell media provides effective cleaning without aggressive abrasion.
As a result, it is a safe alternative to many mineral and synthetic abrasives.
