Dean's TakeFeb 14, 2026

I use TriX when I want to do a quick decon to revive a coating, without going all-in on perfection. Super convenient and user-friendly. I tend to skip this before polishing and go with dedicated products just for the focus, but for a maintenance decon, a two-in-one is a time-saver.

Expert Analysis

The product uses ammonium mercaptoacetate at 20-25% concentration as the primary iron chelator, following the thioglycolate approach for converting iron particles into water-soluble complexes. By combining iron removal chemistry with tar-dissolving solvents in a single ready-to-use formula, it streamlines the traditional two-step decontamination process into one application.

Key Differentiators

  • High concentration ammonium mercaptoacetate (20-25%) provides strong iron chelation performance
  • Dual-action formula eliminates the need for separate iron and tar removal products

Potential Concerns

  • Signal word 'Danger' indicates significant safety hazards requiring careful handling and PPE
  • High concentration of mercaptoacetate may produce stronger odors than typical iron removers
