  • System
    • Immersion
    • Spray Wash (Batch or Continuous)
  • Dilution: 1:32 – 1:9 (3-10%), typically used at 5%

Note: If RP 737 is used as a cleaner, it should be placed in the wash tank by itself without any other aqueous cleaners. However, if RP 737 is used as a corrosion inhibitor along with another cleaner, RP 737 should be added to the rinse tank and the other cleaner should be placed in the wash tank. By adhering to this, the concentration of RP 737 in your tank can be measured by using the Brulin Titration Kit without having interference in your test results from other aqueous cleaners.
