PREPARATION: For best results, ARMOR recommends removing as much dirt, oil and other contaminants from the metal surface as possible, prior to de-rusting
SOAK: Surfaces to be de-rusted must be fully immersed. Metal Rescue™ must maintain contact in wet form with the rusted surface to be effective. As product is used, it will become darker in color. Continue to reuse product until there is a performance drop off. Note: this is a ready to use product, NOT a concentrate.
CHECK: Check periodically. Soak time ranges: Light rust will require 5-30 minutes, moderate rust up to 4 hours and heavily rusted items may take up to 24 hours. Do not leave part in solution after rust is no longer present or metal might become dark.
RINSE: Once the rust has been removed, the surface should be rinsed with water or clean Metal Rescue™ and dried thoroughly.
