Yes, the blades will last a lot longer if you dry them.
A lot longer
I just dab it with a towel then blow on it real hard sometimes using the hair dryer. If any water comes out repeat I’ve had a blade last as long as 6 months. But I don’t have a sandpaper beard
Store them in 90% isopropyl alcohol- no humidity in a covered sealed container. Isopropyl or better (though rather would drink pure grain ethanol alcohol) ethyl alcohol that has virtually no water.
Ethyl and other alcohols will remove water into themselves forming what is called an azeotrope. The metal then has zero to nil water in contact and reduces corrosion to near zero, from plain water. Salt water(ocean environments) are a different matter, electrolysis destroys even so called stainless steel if allowed continuous contact. Boat motor blades are protected by a “sacrificial” aluminum plate that attracts the ions to it instead of the rotor blade, and eventually degrade and have to be replaced. An age old battle.
