Pen Style Scratch Brush Set - 3pc

The fibreglass brush is the softest, ideal for light cleaning and polishing delicate surfaces. The brass brush offers medium abrasion for general cleaning and removing light corrosion. The steel brush is the hardest, best suited for removing heavy rust, paint, or tough debris from robust materials.

Simply twist the end cap of the pen. This retracts the bristles into the protective housing, preventing damage and keeping them clean.

The fibreglass brush may be used for very light cleaning on paint. However, the brass and steel brushes are abrasive and can remove paint. Use with extreme caution and always test first.

Yes, the fibreglass brush is particularly well-suited for cleaning dust and light oxidation from sensitive electronic components and circuit boards. The brass brush can be used for cleaning contacts, but with care.

Lifespan depends on usage frequency and the intensity of the tasks performed. Regular cleaning and proper storage will help extend their useful life.

This set is designed with integrated bristles. Individual brush heads are not replaceable; however, the durable construction aims for longevity with proper care.

Ensure the twisting mechanism is clean and free of debris. Gently try to turn the end cap; if still stuck, do not force it, as this may indicate internal damage. Contact customer support if the issue persists.

You may be applying excessive force or using the wrong brush type for the material. Ensure you are using the appropriate bristle hardness for the task and avoid scrubbing too aggressively.

Verify you are using the correct brush for the material. For softer metals or finishes, use the fibreglass or brass brush. Always test on a small, hidden area first before proceeding with the main surface.
