Fibreglass Cleaning Pen 4mm

The Fibreglass Cleaning Pen 4mm is an essential finds care tool for metal detectorists, archaeologists, and artefact collectors. Designed for controlled, precision cleaning, this pen is ideal for gently removing soil, oxidation, and surface deposits from coins, relics, and metal artefacts without aggressive scraping.

Featuring a retractable pencil-style mechanism, the pen allows you to expose more or less of the fibreglass tip depending on the task. This ensures excellent control when working on delicate finds, while also allowing the nib to be extended further as it naturally wears over time.

The 4mm fibreglass tip offers a slightly broader contact area than fine-point alternatives, making it particularly effective for cleaning larger surfaces such as hammered coins, Roman bronzes, buckles, buttons, and small artefacts recovered while metal detecting.

This cleaning pen is compatible with 4mm diameter fibreglass refills, making it a long-lasting and economical addition to any finds care kit.

  • Ideal for coins, relics, and metal artefacts
  • Retractable fibreglass tip for controlled cleaning
  • Effective on oxidation, dirt, and surface deposits
  • Compatible with 4mm fibreglass pen refills
  • Trusted by UK detectorists and finds specialists

Composite vs Fibreglass Cleaning Tools – Which Should You Use?

Both fibreglass and composite cleaning tools are widely used by metal detectorists, but they serve slightly different purposes. The comparison below will help you choose the right tool for your finds.

Feature Fibreglass Cleaning Pens Composite Cleaning Pencil
Cleaning Action Abrasive fibreglass strands Controlled composite inserts
Best For General surface cleaning and oxidation removal Controlled cleaning and patina preservation
Precision Good (2mm for detail, 4mm for surfaces) Excellent, especially on fine detail
Patina Safety Moderate – care required High – designed to minimise surface damage
Interchangeable Inserts Replaceable fibreglass refills White (firmer) and black (softer) inserts
Recommended Use Initial cleaning and dirt removal Detail work and finishing touches

Detectorist Tip: Many experienced detectorists use fibreglass pens for initial cleaning, then switch to the Composite Cleaning Pencil for detailed finishing and patina-safe work.
