Ignition Spark Plug Brush KLINGSPOR model 358322 – brass wire construction

KLINGSPOR ignition spark plug brush model 358322 is a handheld cleaning tool fitted with brass wire filaments for targeted removal of carbon deposits and light corrosion from spark plug electrodes and threads. Designed for workshop and garage use, the brush offers a compact shape and firm brass wires that clean contact surfaces without excessive abrasion. The tool is intended for maintenance of automotive and small engines where restoring good metal-to-metal contact and clear spark paths supports reliable ignition.

Advantages

The brass wire construction provides effective removal of soot and oxidation while being softer than steel wires to reduce the risk of damaging delicate electrode shapes. Its compact handheld form allows controlled pressure and precise access to the electrode gap and threaded areas. The brush is non-powered and requires no consumables other than replacement when bristles wear, offering a simple, low-maintenance solution for routine spark plug servicing.

Suitable for

• Cleaning spark plug electrodes and threads on petrol engines
• Maintenance of lawn mowers, chainsaws and other small engines
• Workshop and garage preparatory cleaning before testing or reinstallation
• Removing light corrosion and carbon buildup without intensive grinding

Key specifications

• Filament material: brass wires
• Tool type: handheld brush for spark plugs
• Intended use: cleaning electrodes and threaded areas
• Operation: manual (non-powered)
• Design focus: precise, controlled cleaning with reduced abrasion

How to use

Ensure the engine is cool and the ignition system is disabled or the battery disconnected before beginning. Remove the spark plug from the engine and use the brass wire brush to gently clean the electrode tip and the threaded section. Apply light, controlled strokes to remove loose carbon and corrosion; avoid aggressive scrubbing that could change the electrode geometry. After brushing, blow out any debris with compressed air or wipe with a lint-free cloth and inspect the electrode gap and sealing surfaces before reinstalling the plug.

Usage recommendations

Use the brush for routine maintenance and targeted cleaning only. Replace the tool when bristles become deformed or excessively worn. Do not use the brass wire brush on ceramic insulator surfaces or where structural repair of a heavily damaged spark plug is required. Where precision gap and electrode condition are critical, inspect with appropriate gauges or replace the spark plug if wear persists.
