- Environmental and safety considerations: Look for products that minimize phosphates and harsh chemicals, and consider products designed for high-pressure systems if you use automated bays.
- Surface compatibility: Ensure the formula is safe for painted surfaces, aluminum, and other materials used on trucks and trailers to avoid etching or corrosion.
- Dilution guidance: Effective dilution rates balance cleaning power and economy. Favor products with clear dilution guidelines for predictable results.
- Availability and support: For fleets, select suppliers offering reliable restocking options and technical support for optimal wash routines.
- Cost per wash: Compare the cost per gallon or per effective use, factoring in dilution and the number of vehicles in your fleet.
- Storage and handling: Bulk containers should be stored safely; consider containers with ergonomic handling features and closures that prevent spills.
