Fibreglass Scratch Brush Pen – 4mm Replaceable Tip, 120mm

The Fibreglass Scratch Brush Pen is a precision jewellery cleaning and surface preparation tool designed for cleaning, polishing, deburring and removing surface residue from small metal components.

Featuring a 4mm fibreglass brush tip and a convenient twist-action mechanism, this pen allows the brush fibres to be extended or retracted for controlled, detailed work.

The replaceable fibreglass insert makes it a practical, reusable tool for jewellers, goldsmiths, silversmiths, watchmakers and precision craftspeople.

With its 120mm overall length, lightweight construction and white plastic handle, this scratch brush is ideal for working on small areas where a larger cleaning brush would be less practical.

How to Use

1. Extend the brush: Rotate the pen mechanism to expose a short length of fibreglass fibres.
   
2. Clean the surface: Apply gentle, controlled strokes to the area requiring cleaning or surface preparation.
   
3. Adjust as needed: Extend additional fibres gradually as the brush wears.
   
4. Retract after use: Turn the mechanism to retract the brush for storage.
   
5. Replace the insert: Fit a compatible replacement fibreglass tip when the existing insert is worn.
   

Tip: Keep the exposed fibres short for more controlled, concentrated cleaning. Longer exposed fibres provide a more flexible brushing action.

A fibreglass scratch brush provides a convenient way to clean and lightly abrade small areas without using a large wire brush or powered polishing tool.
Its fine fibres can reach intricate details, while the twist-action pen mechanism allows you to control the exposed brush length.

Important Usage & Safety Notes

• Fibreglass fibres are abrasive and can scratch polished, plated or delicate surfaces. Always test on an inconspicuous area first.
  
• Wear suitable eye protection and gloves when working with fibreglass brushes.
  
• Avoid inhaling loose fibres or dust, and clean the work area after use.
  
• This tool is intended for controlled cleaning and surface preparation, not guaranteed scratch-free polishing.
  
• Replacement inserts must be compatible with the 4mm brush pen.
