Freiclean NDR is a pH neutral liquid cleaner designed to safely remove rust from corroded steel substrates. It may be used in a recirculating spray, immersion, and spray wand applications. After rinsing, the de-rusted parts may be immediately treated in a coating process or dried and protected with a corrosion control product.

Fill the process tank half full with water and add desired volume of FREICLEAN NDR. Fill to final working volume and mix. Heat the solution to operating temperature as desired. It is recommended to initially use Freiclean NDR at 200 gallons per 1000 gallons of process bath.
The concentration of ferrous iron in a FCLNDR cleaning solution can be used to estimate when to dump the bath. Each application will have a ferrous iron level at which the FCLNDR bath will
become ineffective. This level can be identified through experience on the particular line.
Procedure: Measure a 10ml sample into a beaker and add about 15 drops of Testing Solution #44, then titrate with Testing Solution #18 to a pink color that last 20 seconds. Each point (1.0ml) of testing Solution #18 is equivalent to 0.1% iron in Solution.
Processing parameters can vary from application to application. Your Freiborne Sales and Service
Representative will assist you in determining the best processing criteria for your application.
