PRODUCT DIRECTIONS:
In some cases it might be necessary to use full strength. However, due to its high phosphoric acid content dilution can range from 1 to 1 up to 1 to 4. Apply to soiled area with brush or sprayer and allow to soak for 5 to 10 minutes, then flush out with clean water. A dip tank method can be used if suitable plastic or rubber‐lined tank is available. It can be heated up to 125 degrees F. Watch carefully that chemical solution does not attack the part being cleaned or descaled.
