• Designed to attack road film, grease, traffic residue, and stubborn grime before the main wash stage begins
• Functions as a front-end presoak to improve downstream wash efficiency and overall cleaning consistency
• Helps reduce reliance on aggressive brushing or overfeeding of later-stage detergents
• Suitable for automatic systems, fleet wash bays, truck wash programs, and manual pressure-wash setups using a presoak step
• Best positioned where heavy roadway soil and oily contamination need to be softened before the main cleaning cycle
• Practical for operators seeking stronger first-pass cleaning performance in multi-stage wash programs
