Protocol K-390 is a hydrofluoric acid (HF) free aluminum brightener designed with cutting-edge technology that eliminates HF’s requirement. It uses a low toxicity acid salt specially designed to remove dirt, grime, and oxidation from aluminum surfaces, leaving them bright and clean.
Product Directions
- For standard cleaning, dilute Protocol K-390 10:1 and apply to the aluminum surface.
- Protocol K-390 takes longer than HF to act, but this allows for more control and is less prone to burning the metal.
- Rinse after a few minutes of contact time.
- To remove stains caused by overuse of HF, use this product straight, followed by a rinse.
- DO NOT apply this product through a high-temperature pressure washer like a Hotsy.
