I
The cleaning measures described here for older and more severe areas
of corrosion are recommendations of the German industry association for
home, heating and kitchen technology (Industrieverband Haus-, Heiz-
und Küchentechnik e. V. (HKI)).
The cleaning measures for older and more severe areas of corrosion may
only be carried out by trained personnel in compliance with the existing
regulations.
Warning!
Caustic substances!
The acids used for removing areas of corrosion can cause injuries and also
caustic damage to objects (e.g. clothing). Contact with the eyes can cause
irreparable impairment of sight. In the worst case, total loss of sight could
result.
Wear protective clothing (protective eyewear, protective gloves etc.).
Persons not involved in cleaning must be kept at a distance.
Remove areas of corrosion with 2-3 % oxalic acid.
Use 10 % nitric acid if cleaning with oxalic acid is unsuccessful.
