An effective, very fast-acting preparation, which, thanks to the use of modern components, does not adversely affect steel, additionally protecting the element from corrosion.
Apply the preparation to the element, preferably by spraying, wait a few minutes (this is the time necessary for the chemical reaction to occur), wipe with a cleaning cloth and finally rinse.
The product can be diluted in water (1:1-1:2), in case of small iron oxide film, keeping in mind that any dilution means a decrease in performance and reduced corrosion protection.
