Quoted from Syco54645:Since the dust may contain lead couldn't that be bad for your dishes afterwards? I mean it cant all get flushed out.
Your dishes don't care about lead poisoning, the people eating off those plates might be a different story. This is the only reason I have never done the dishwasher method. I am generally not a "nervous Nelly" but putting lead, lead/dust into a device that will clean items I and my kids will eat off of? No thanks. I would be willing to bet you can not find one poison control expert that would endorse this practice. Do I really think there is a danger? Probably not. However, I doubt you can find any research that shows that it is safe because lets face it, the general population would not consider putting lead into a dishwasher
