Frequently Asked Questions:

What is the primary advantage of Walnut Shell Sand over traditional mineral abrasives?

The primary advantage is its unique balance of hardness and gentleness. Unlike sand, garnet, or aluminum oxide, walnut shell cleans effectively without etching, pitting, or damaging the underlying substrate. It is ideal for cleaning soft metals (aluminum, brass, copper), composites, fiberglass, wood, and delicate machinery.

The general rule is: use the largest mesh size that achieves your desired result. Larger particles (20/40) provide aggressive cleaning and fast stripping. Medium particles (40/60) are general-purpose for cleaning and light polishing. Fine particles (60/120 to 60/200) provide gentle polishing, cosmetic exfoliation, and precision cleaning.

How do I choose the right mesh size for my application?

Yes, it is excellent for blast cabinets. Its low dust properties and non-damaging nature make it ideal for cabinet use. It can be recycled multiple times (typically 5-8 times) depending on the application, making it economical and efficient.

Is Walnut Shell Sand safe for use in blast cabinets?

Yes, 60/120 and 60/200 mesh sizes are specifically suitable for cosmetic applications. The fine, smooth-edged particles provide gentle mechanical exfoliation without the sharp edges found in ground nut shells or mineral exfoliants. It is commonly used in body scrubs, facial cleansers, and hand soaps.

Can Walnut Shell Sand be used in cosmetic products for the face and body?

Store in a cool, dry place in sealed containers to prevent moisture absorption, which can cause clumping. When used in blasting applications, it is recommended to use with a dehumidifier in humid environments. While generally safe, use standard PPE (dust
