Sant Nitric Acid 50% is a clear, slightly yellowish solution with a density of around 1.3, which can be used as an acidic detergent in the food industry. This product can remove mineral deposits and alkaline-resistant calcium deposits (formed due to heating hard water or food residue on surfaces), as well as mineral residues such as hard water scale, milk scale, beer scale, and calcium oxalate.

It is also effective in neutralizing residual alkaline detergents. In food factories that use deionized water for cleaning and do not have high levels of magnesium and calcium ions in their products, cleaning can be done every three months, and there is no need for daily use of this product.

Overall, considering that nitric acid can cause corrosion on metal surfaces, it is recommended not to use it on a daily basis.
