I have always been very hesitant in using acidic solutions for cleaning purpose on metal surfaces. Being a long-time firearms collector, I believed in the formula
iron/steel + acid = corrosion.

The keris that I intend to clean is -- except for several black rust spots -- a very nice dapur Parungsari in a grey/white condition with smooth edges and beautifully executed luk rengkol. All I want is to preserve it in this shape.

Hello Heinz,

when you clean a blade in the way I have described and control it by time and don't let it to long inside only the corrosion going. I have cleaned many different blades like this and every time have had good results.
