Brass Wire Wheel used to Clean 350 Chevy V8 Valves

I searched around on the net for the best way to clean those nasty engine valves and many folks said to use a brass wire wheel to get the job done. I am glad to say this is very true as I just cleaned four valves myself about an hour ago. The brass is soft enough not to damage the steel valve but strong enough to get rid of that baked on gunk. Check out the picture below.
