What reviewers say
Synthesized from 40 reviews · 100% verified purchases.
For maximum cleaning power, choose a product with high PEA content like Red Line SI-1 or Chevron Techron, but expect to use multiple treatments for severe deposits. For long-term storage, use a dedicated stabilizer such as STA-BIL or Star Tron to prevent gum and starting problems.
