NuGeneration Technologies’ AquaKlean STC-RP is a highly alkaline, low-foaming liquid cleaner for use in both spray and tank applications with flash rust inhibitors that yield extended indoor rust protection for up to 90 days. AquaKlean STC-RP can be used at ambient temperatures for the most demanding cleaning jobs on ferrous metals and stainless steels. With a lower conductivity than most highly alkaline cleaners, AquaKlean STC-RP allows for faster, more complete rinsing.


AquaKlean STC-RP was formulated to provide a solvent-free, advanced cleaning of ferrous metals and stainless steels. At temperatures above 110°F, AquaKlean STC-RP will not foam.

Removes inks, polishing and buffing compounds, grease, oils, chlorinated oils, fingerprints, drawing compounds, metalworking fluids and carbonaceous deposits. AquaKlean STC-RP is a solvent-free product and releases metal complexes during water treatment. 

Directions for Use

AquaKlean STC-RP is effective at ambient temperatures. However, it is normally used at 1 – 10% by volume of water at 70 – 190 °F for 5 seconds to 5 minutes.  The parameters can vary depending on the type and extent of soils being removed. Temperatures may be increased slightly for shorter time cycles.

Do NOT use on Aluminum, Copper, Zinc, Lead, Tin or their alloys (Brass, Bronze, etc.).

Safe for use on Steel, Cast Iron, and Magnesium.
