Car shampoo and pre-wash by contamination type: AG Detail 3-piece set
AG Detail is a Korean car-care brand, and this three-product lineup includes Blue Edge Shampoo, Red Dissolve Dual Wash, and Indigo Core Pre-Wash. The products divide everyday mitt washing from acidic and alkaline pre-wash steps by type of contamination. Verdict: an interesting contamination-based wash routine, but not a record of real-world results.
