I need to restore a 56 Merc Carter WCFB. I've used many products but not lately. I do not have a sand blaster. It is all apart completely all shafts and butterflys. I have cleaned small steel parts by soaking them in Coke or Pepsi and they come out pretty nice. I now have a sonic cleaner any ideas on what product to use in it? How about the aluminum center section and top? I see even Wally World sells carb parts dip but I haven't used any since the new haz rules....any comments are welcome.
