Not sure if anyone has talked about it recently, or at all, but if you dry off a disposable razor after use, then submerge it in mineral oil (I use a solo cup with about an inch of oil in the bottom) the blades don't rust or go bad nearly as fast and stay sharp for a hella long time. As an example, using this method, I use 2-3 disposables per year, instead of 1-2 per week like normal.
