I first started this experiment about a year ago using baby oil, which worked fine, but one day I spilled it and refilled the cap with water ... that was about 3 months ago.
I get 2 - 3 months also with cheap throw away razors.
Do you actually clean your blades too after use? I know you said you tap the blades to clear out water and stubble, but I have a small brush I’ll run over my blades to accomplish the same purpose.
Definitely going to try this. I just bought a set of Quattro blades and they ain’t cheap. So I may as well make these last as long as possible. Thanks again.
