I have been using a straight for about a month now, and I love it, I have tried to be careful and keep it dry, drying with a towel after every use. today I noticed when I was opening it, it felt tight and looked at the area near the pivot and saw rust around the pivot and the back of the tang. I hadn't noticed this before.

1. How do I remove the rust?
2. Should I remove the pins in the pivot and clean the blade ? I have a feeling it is rusted in between where the handle and the blade meet.
3 How do I stop this from happening? is it possible not to get the razor wet while shaving?

Thanks
