I would definitely think so. If I owned one, I would at least keep the threads and contact points shiny. Sorry if I'm repeating myself here (feelings of deja vu coming on): Simichrome works wonders on brass and copper, but honestly, white regular Colgate toothpaste and some toothbrush scrubbing or finger rubbing and then a rinse in hot water has been all I've ever needed to clean everything from copper to silver. It's cheap too since you can buy the dollar store made in Pakistan Colgate and not worry about the propylene glycol or whatever... I'm personally not a tarnish fan so I just gave my Peak Logan brass the Colgate treatment last night and it looks great!
Also, I have to make note of which of you are peeing on your lights in this thread in case I ever decide to buy one of these on the aftermarket! 😀
