Ok it is 9.10 pm central time and I did rub them by hand to make sure all the sot was gone. i could see it wiping off. I used a tooth brush to get the threads. The aqua ones are 4 different shades. cool. But also I can see all the chips on them to. This stuff is bad for you so read the warnings very careful. and Be safe. They have a cleaning section in here I just wanted to show it in progress. at least this one. Joe
