Hi Sonofjim,
Here is my opinion on this. I'm not a water expert but I was a licensed water plant operator in Florida for a decade and a half, so I know enough to be dangerous on the subject. Steam will be purer, but there are some compounds that will still present. Some are ionic compounds and will not be removed by boiling. If this was not true we could all make our own pure water at home. Too bad, because it would save us all a lot of money.
However, I do agree with you that the distilled water does work fine for steaming LPs. I think the biggest reason to use as pure of a water source as you can find is to keep the steamer clean and working properly. If you have ever replaced a heating element in an electric water heater you probably have seen how much stuff gets built up over time on the element from compounds in the water. Usually this stuff is calcium and/or magnesium compounds. Anyway, you don't want this stuff in your steamer if you can easily avoid it.
I think that if you follow a process like Stltrains demonstrated, or if you just immediately follow the steam with a cleaning solution like I do, you will keep the bad stuff from the LP and the water in suspension long enough to be able to get it off the record. IME, the best way to get this all off is to vacuum it up.
