#1 Citric Pre-Soak – Polish-Safe 2-Step Truck Wash Presoak

#1 Citric Pre-Soak is a versatile, citric acid-based, low-pH presoak designed for professional two-step truck and fleet washing. This Step 1 chemical helps loosen road film, remove oxidation, and lightly brighten aluminum surfaces while offering compatibility with polished aluminum, painted surfaces, and glass when properly diluted and used as directed.

Ideal for fleet-washing contractors who need effective cleaning without the aggressive aluminum-brightening properties of hydrofluoric acid-based products, Citric Pre-Soak can be paired with polish-safe alkaline detergents or more aggressive Step 2 soaps depending on the vehicle and application. Its pleasant orange citrus fragrance and versatile cleaning performance make it a practical choice for routine fleet maintenance and touchless washing.
