Gunson 77111 Spark Plug Clean

**Editorial Review of the 77111 Spark Plug Cleaner** The 77111 Spark Plug Cleaner presents itself as an appealing and cost-effective solution for vehicle enthusiasts looking to extend the life of their spark plugs. Many users have noted its effectiveness, stating that it performs comparably to more expensive, industrial-grade machines. The ability to clean the crevices of the spark plugs, especially the ceramic insulator, is a highlighted benefit as it cannot be accomplished easily using conventional methods. However, some users suggest a two-step process for optimal results. A pre-cleaning of the spark plugs with a wire brush is recommended to ensure that the electrode area is thoroughly cleaned. This advice indicates that while the cleaner is effective, it may not fully address severe carbon build-up on the electrode itself, which is crucial for overall performance. Despite many positive reviews emphasizing the machine's sturdy Construction and affordability, there is mixed feedback regarding its safety and operational design. A significant concern arose from one user who reported a potentially damaging situation where blasting grit remained lodged within the spark plugs after cleaning. This issue raises serious safety concerns about the device, especially for those using it on high-performance engines. It is essential for potential buyers to remain cautious and ensure they thoroughly clean the plugs with compressed air post-usage to avoid similar hazards. Overall, the 77111 Spark Plug Cleaner is a practical tool for individuals looking to maintain their spark plugs economically, provided they follow best practices to mitigate any risks associated with dirt and abrasives left behind. **
