Teknos Rensa Steel is a very efficient citric acid based detergent for pretreatment of galvanized sheet-iron and zinc-coated steel surfaces before painting.

Best Uses

Teknos Rensa Steel is a pretreatment agent for maintenance painting. It is primarily meant for washing new untreated zinc-coated and galvanized steel surfaces before painting with Teknos Kirjo or Teknos Kirjo Aqua paint for sheet-iron roofs. It removes very efficiently zinc salts, grease, dirt and other impurities. It is also suitable for washing of previously painted sheet-iron roofs before maintenance painting.


Dilute Teknos Rensa Steel with water depending on the purpose of its use:

For washing of and pre-treating surface to be painted: 1 : 3 (1 litre of detergent to 3 litres of water) For very dirty surfaces: 1 : 1

Remove loose dirt and dust from the roof by brushing.

Apply the detergent to the surface to be cleaned by using e.g. a brush or low-pressure spray (so-called garden spray). Let it act for approx. 10 minutes. Enhance the cleaning effect by brushing strongly.

The detergent must not dry on the surface to be cleaned - wet the surface again with the washing fluid, if needed. Rinse the surface thoroughly with a plenty of clean water. Rensa Steel is an efficient, but environmentally friendly and biodegradable product. However, using the detergent must be followed with a reasonable caution. Avoid skin contact and breathing the spray mist. Protect eyes from splashes. More information from product’s Safety Data Sheet.
