Process for removing Scale from Steel/Cast Iron

Rodastel 30 was used as the acidic based cleaning detergent is very efficient at removing scale and oxidation. The tank was diluted with a 5% concentration of Rodastel 30 and allowed the reach the required temperature of 45°C whilst degassing. The parts were cleaned for 20 minutes in the Rodastel 30, Initially you can see clouds of contamination being removed. The part were then rinsed in tap water for 2 minutes. To remove any minerals which may cause staining the part was then rinsed in DI water for 2 minutes. Finally, the parts were dried in the Versa hot air dryer for 5 minutes at 70°C.

Note: It is recommended to use a corrosion inhibitor to the final DI rinse so the parts can dry oxidation free.
