Brushes & Spray Bottles FAQ

Wire brush or soft brush for rockhounding?

Use wire for hard matrix on durable specimens; switch to soft nylon for fossils, crystal faces, and final cleaning. When in doubt, start soft.

Why do rockhounds spray water on dry rock?

Water reveals true color, translucency, and banding that dry dust hides — especially for agate, jasper, and petrified wood in desert conditions.

Can I use a toothbrush instead of a field brush?

A toothbrush works in a pinch for delicate work, but field brush sets have stiffer options and longer handles for matrix you cannot reach with a small head.
