VpCI®-418 L / VpCI®-418 LM Heavy Duty Alkaline Cleaners


VpCI®-418 L/418 LM are non-foaming, heavy-duty alkaline cleaners/degreasers for cleaning industrial, oil field, commercial, and marine equipment. VpCI®-418 L/418 LM are designed for power-washing machinery, high-agitation parts washers, and high-pressure spray washers.


VpCI®-418 L/418 LM are non-flammable, nitrite-free, and do not present disposal problems associated with most phosphate cleaners.
VpCI®-418 L/418 LM contain inhibitors to protect metal parts from corrosion after cleaning. They have a unique ability to remove difficult deposits such as heavy hydrocarbons, greases, drawing and buffing compounds, and mill and machinery oils.


• Nitrite-free
• Will not affect paint adhesion qualities
• Safe to use on glass and most plastics
• Non-foaming
• VpCI®-418 LM is silicate free and leaves behind no residue


• Offers unique cleaning action for removing hydrocarbon deposits
• Prevents flash rust
• Provides multimetal corrosion protection


Effective Uses:
• Machinery, engine blocks, or forgings coated with grease or oil deposits
• Plate, sheet metal, and metal castings covered with oily films prior to painting or pickling
• Metal parts contaminated with stamping, drawing, or buffing compounds
• Pressure washing

VpCI®-418 L/418 LM can be applied using power washers and sprayers. It requires mechanical action to be effective. Mix VpCI®-418 L/418 LM into water until fully dissolved. Take pH and refractometer measurements to establish benchmark readings.
