Wash solutions

Thunderbolt or Hellcat?

Both are alkaline truck-wash detergents. Choose for your water, soil and application system.

Water hardness

Ver-tech lists Thunderbolt for 0–10 grains and Hellcat for 0–20 grains. Check your water rather than assuming a stronger mix will solve hardness problems.

Application matters

Thunderbolt has separate high-pressure, brush and Foam Maxx dilution guidance. Hellcat lists touch-free, debugger and degreasing dilutions. Follow the exact product instructions; ratios for different application systems are not interchangeable.

Both are manufacturer-listed alternatives for the second step after Citric Clean. Review the two-step path.

This is a manufacturer-information comparison, not a Wet Willy’s side-by-side performance test. Verify specialty finishes before use.
