Tried a straight for the first time this morning. Have been shaving with a DE for about a year so have the prep down pretty well. Bought a shave ready razor from an SRP member and gave it a go. Was much smoother than I expected, no nicks or cuts. But had a horrible time figuring out how to do chin and left side of my face ( I am left handed). Did a couple of passes WTG and XTG on the areas I could reach. Didn't get very close but for the first try I thought it went fairly well. Very difficult to judge proper angle, and felt helpless with the razor in my right hand. Finished off with a DE and got BBS shave. I was encouraged by first go. Dried the razor and put it in cupboard. Came back later to try a strop and found black spots all over the razor. Apparently I didn't get it as dry as I should have. How can I remove these and avoid them in the future?
