I like my Regent NEW LC. It actually lives up to the hype. It cuts through my whiskers like a hot knife through butter. However, I just noticed more tarnishing on the inside of the top cap and baseplate than I remember when I got it in the mail. I've had it assembled without a blade for a few days and only washed the top of the head with a little dawn and water. I guess some of it seeped into the gap and caused the tarnishing. It's all stained a mostly brown color. Is polish the way to get rid of it? Can I expect this to come back every time it gets wet?
