The AUTOOL HTS558 walnut blaster is designed to break down and evacuate viscous carbon build-up without harsh chemicals or abrasive metal media. Its reusable blasting head, built-in dust filter, and walnut grit recovery loop let you clean engines on many modern vehicles while protecting intake surfaces and downstream exhaust components.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the walnut blasting method clean intake valves effectively?\u003c\/h3\u003e\n\u003cp\u003eWalnut shell grit cleans by mechanical abrasion: millions of tiny pores and hard particles knock carbon off metal surfaces without etching or gouging.
