Description
STR-4075 Vehicle Pre-Soak is an industrial-grade surface penetrator designed for use before vehicle washing to loosen stubborn contaminants like bugs, grease, road grime, tar, and oil film. Applied during the pre-wash stage, it significantly reduces manual scrubbing and improves final wash results.
The formula is phosphate-free and compliant with AQMD Rule 102, containing zero VOCs and no smog-contributing ingredients. It is safe on fine finishes, including painted surfaces, aluminum, glass, plastic, and polished metal. With a powerful citrus-based detergent blend and high-foaming action, STR-4075 is engineered for professional vehicle wash bays, large transportation fleets, and auto detailers.
