Semi-Aqueous Cleaning – The Best of Both Worlds.

A Smarter Way to Tackle Stubborn Contaminants:

Industrial cleaning often demands a solution that is both powerful and safe. Traditional solvents may achieve strong results, but they bring environmental and safety concerns. Purely aqueous systems, while safer, sometimes lack the strength to remove heavy, oil-based contaminants.

Metalwash’s new Semi-Acqueous Solution bridges this gap, offering the cleaning power of solvents combined with the safety and sustainability benefits of water-based solutions.

Proven Performance in Real-World Trials:

Extensive testing has shown that the semi-aqueous solution is particularly effective against some of the toughest contaminants, including:

  • Silicone grease
  • CV joint grease
  • Copper Cote
  • Liquid PTFE
  • Heavy lithium grease

In controlled trials, parts were cleaned thoroughly with no visible residue, no flash rusting, and no degradation. Results were consistently achieved within just five minutes of cleaning across manual, high-pressure, and automatic aqueous parts washers.

Why Choose Semi-Aqueous?

Improved Cleaning Power:

This solution outperforms water-based detergents alone, especially when removing hydrophobic greases and oil-based residues. In fact, it proved more effective than kerosene during early trials.

Reduced Environmental Impact:

By replacing traditional solvent-based cleaners, businesses can significantly reduce their environmental footprint. When paired with biodegradable solvents and surfactants, the semi-aqueous solution supports environmental management systems, including ISO 14001 initiatives.

 

Cost Efficiency:

Kerosene is not only environmentally taxing but also costly, as it must be used neat (100%). In contrast, the semi-aqueous solution can be diluted with water at concentrations ranging from 5% to 50%, offering substantial cost savings without compromising performance.

 

Designed for Versatility:
