Try one blade you don't favor too much and time will tell, but I dont't think that could hurt a lot.
General advice though about soaking : never mix metals. So try avoiding soaking a full razor, just the blade, since the metals you can find for example on the washers might create an oxydo-reduction reaction. And try soaking razors that are "alike" in the same bath.
