After treating a cast-iron part with Rustbeeter™, the metal surface sometimes has a white, chalky powder on it. How do I get rid of it?
Occasionally, a white powder will adhere to the surface of cast-iron part treated with Rustbeeter™. Simply put the part back in the Rustbeeter™ slurry and then, without rinsing, submerge it in a small container of clean tapwater. The diluted solution will remove the white powder. The part is then ready to be rinsed and to be applied with a surface treatment.
