One of the most important detergents that is very practical and almost all of us use it, is a scaling liquid. There are different types of scalers, among which Negarin scale liquid is one of the best and most significant types of scale collectors. Given that unprincipled compounds of scaling liquids can endanger human health, one of the problems and drawbacks of scaling liquids in the past was the use of salt and chlorine ink compounds, which has now completely changed thanks to advances in this industry. . No salt or chlorine ink was used in Selda scaling liquid. This feature makes this scaling liquid have a pleasant aroma. As we said before, no chlorine or salt ink is used in making this product and it does not contain any solvent. This feature makes Selda scaling liquid in the category of environmentally friendly hygienic detergents and does not emit any toxic gases. Note that a scaling fluid is designed to remove water hardness deposits and should be used in its proper place. It is often seen that these sediments are colored like yellow, red, orange, etc., which is due to the presence of some metal ions and minerals in these sediments. Therefore, be sure to use the scaling liquid in its proper place on the glazed surfaces of bathrooms and avoid using it on sedimentary stones such as marble, because marble is composed of sediments such as water sediments.
