Rensa Steel is a very efficient citric acid based detergent for pre-treatment of galvanized sheet-iron and zinc-coated steel surfaces before painting.
Rensa Steel is a pre-treatment agent for maintenance painting. It is primarily meant for washing new untreated zinc-coated and galvanized steel surfaces before painting with Kirjo Aqua paint for sheet-iron roofs. It removes very efficiently zinc salts, grease, dirt and other impurities. Rensa Steel is also suitable for washing of previously painted sheet-iron roofs before maintenance painting. Rensa Steel is a biodegradable product. It meets the requirements by OECD and by the Detergent regulation of European Parliament and the Council on detergents for biodegradability (OECD 301B, EC 648 / 2004).
