Scratch brushes are very versatile types of brushes. They can be used for various types of cleaning, deburring, and removal of material from an array of surfaces. Acid brushes are typically one-time or repeat use to apply acid, glue, paste, soldering, or for touch-up, dusting, or other general-purpose applications. Artist brushes can be used for detailing, applying solvents in small spaces, or for creative painting projects.
