Merkur provide the following information regarding the Merkur Vision 2000 razor:
“In order to prolong the life of your safety razor it is necessary to clean the moving parts of your razor after each shave, for example with a soft nail brush or tooth brush. Only if the soap residue is removed thoroughly, the mechanics of your razor will work satisfyingly in the long run. We suggest completely breaking down your razor for a thorough cleaning with each new blade that you install in the razor.
In contact with hard, calciferous water all parts of the razor need to be de-calcified regularly, depending on the concentration of lime in your water. The parts should be put into a diluted and lukewarm decalcifying solution every few minutes. It is also recommended to move the mechanical parts a few times, so the solution can get into every crevice.
A more extended contact with the decalcifying solution will destroy the surface and corrode the metal of your razor.”
The Merkur Vision safety razor features a number of moving parts to operate the butterfly mechanism and provide adjustability. It is important that these steps are carried out to ensure the longevity of this razor.
