Hello to all

i am a beginner and i'm pleased to join to you

I've noticed the appearance of small spots on my straight razor (Dovo) ,I think it's after i use hot water for cleaning !!! (I'm not sure)

It is staying, despite trying to remove by water or razor oil

so my questions are:

What is it?

What is the reason they appear?

Does it affect the skin when shaving?

How to disappear?

thanks
