proven soft abrasive

Walnut Shells have been used for cleaning and blasting operations for a very long time.  This multi-purpose media comes in different sizes depending on your needs.  We consider shells a “crossover” media – gentle enough to work safely on soft metals and wood construction materials, but can also strip paint and remove tough coatings when applied at higher pressures.  Walnut Shells are very durable which allows for reuse of the shells several times before it breaks down.

Made by Mother Nature

– but be careful – a blast media nut is still a NUT!

This product is all-natural, biodegradable, non-toxic, and landscape-safe.  However, if you or any of your co-workers have a nut allergy we recommend using an alternate media.
