Dean's TakeMar 9, 2026
Gyeon's Q²M Iron has a pretty strong concentration of ammonium thioglycolate which explains why I always found this product so effective. A good option for decon.
Expert Analysis
Gyeon's thioglycolate dose is near the top of the category. Gyeon says it's safe on even the most delicate materials, and the neutral pH supports that for paint and coatings.
