Mammoth Hydro 720 Premium Snow Foam Lance

The Mammoth Hydro 720 Premium Snow Foam Lance is a professional-grade pre-wash tool engineered to deliver dense, consistent foam coverage for safe and effective vehicle cleaning. Built with precision-machined internals and a high-capacity solution bottle, the Hydro 720 produces thick, clinging foam that softens dirt, traffic film and grime before contact washing, significantly reducing the risk of swirl marks.

Designed for enthusiasts and professional detailers alike, the Hydro 720 features fully adjustable dilution control and spray pattern tuning, allowing exact foam thickness and coverage to be dialled in for everything from heavy winter grime to light maintenance washes. Its robust construction ensures long-term reliability even with frequent use of strong pre-wash chemicals.

HQ Suggests (Tips & Insights):

• 💡 Adjust foam thickness using the metering valve rather than over-concentrating chemicals.
• 💡 Apply foam from the lower panels upward to ensure even dwell time across the vehicle.
• 💡 Allow foam to dwell for 3-5 minutes but never let it dry on the surface.
• 💡 Rinse the lance with clean water after use to prevent nozzle or mesh blockage.
• 💡 Works best with high-lubricity snow foams and citrus pre-washes.
• 💡 Ideal partner for safe two-bucket wash methods and ceramic-coated vehicles.
