WaterBoss 750 Soft Wash Gun – Built for Professional Soft Washing with Sodium Hypochlorite (SH)
Stop replacing cheap pressure washer guns that fail after a few months of bleach exposure. The WaterBoss 750 Soft Wash Gun is purpose-built for professional soft washing applications where sodium hypochlorite (SH) is used every day. Unlike traditional pressure washer guns that use brass internal components prone to dezincification and corrosion, the WaterBoss features a lead-free stainless steel wetted path, dramatically increasing durability when used with bleach-based cleaning solutions.
Designed for gas-powered soft wash roof pumps like the Comet P40, AR45, and similar 12 GPM systems, this professional-grade soft wash gun delivers outstanding chemical resistance, operator comfort, and reliable performance on every job.
Whether you're cleaning roofs, siding, stucco, brick, concrete, fences, driveways, commercial buildings, or exterior surfaces, the WaterBoss 750 helps you work longer with less fatigue and more control.
Why Professionals Choose the WaterBoss 750 Soft Wash Gun
Engineered Specifically for Bleach (SH)
Most pressure washer guns were never designed for sodium hypochlorite. Their brass valve seats quickly corrode, causing leaks, sticking triggers, and premature failure.
The WaterBoss eliminates this problem by using:
- Lead-free stainless steel wetted components
- No brass inside the chemical flow path
- Excellent resistance to SH and soft wash surfactants
- Longer service life under daily professional use
This makes it one of the best soft wash guns available for contractors who clean roofs and building exteriors every day.

For maximum service life:
- Flush with fresh water immediately after every job.
- Never allow SH to remain inside the gun overnight.
- Store in a dry location.
- Inspect O-rings periodically.
- Lubricate seals as needed using manufacturer-approved lubricant.
Routine maintenance helps ensure years of dependable service.
