Hello and welcome. Out of interest, You don't say what bandsaw you have.
Assuming you don't have a large stenner type log converting saw bench, which will be used with the blade running on convex ground steel wheels.
Any oil/wax etc, applied on you're blade in the saw will cause running problems, as they run on rubber, or nylon type tyres.
Should you want to clear any rust formed on the blade in between use, What I do is, UN PLUG IT, and, just use some fine sandpaper held against the blade's inside, but away from the teeth, and move the saw blade upwards, by turning the wheel carefully and making catching fingers and teeth less likely.
Any spare blades would be best coiled, (A bit of an art form in its self)! and checked/ cleaned before fitting, tracking etc.
HTH Regards Rodders
