With the proper care, our razor should last for years.  As with any metal, if left in humid conditions for extended periods of time, the razor would be subject to degradation. We recommend that after every use, give the razor a quick rinse under the tap (especially the back where oil and soap residue can remain) then wipe dry and store somewhere cool and dry. Each time you change the blade, you can give it a proper rinse-through between the head but no need to dismantle after each use.
