Abstract
Novel acid-based chemistries that can be used in various cleaning, de-scaling, rust-removal, brightening, etching and other similar applications, including, but not limited to, those based upon hexafluorozirconic acid and other additives, such as urea in some applications, which are effective for a wide range of applications, while avoiding the health, safety and environmental issues that are often associated with the use of hydrochloric acid and other toxic chemistries.
