You're right. Try to use oil on lampwax(paraffin) base.

Jimmy, all my razors in oil and in their cardboard boxes.
You never thought, why many old Sheffield razors with patina, but without the rust. And they in their own boxes for 100-150 years.:)

I can only add, keep the razors in their cardboard boxes.
Cardboard absorbs moisture and allows razors to breathe.
