Cold wash

The early Blackstone automatics did offer a cold wash option. The temperature selections were Hot, Medium, and Cold. Then, as far as I can figure out, the cold wash option pretty much disappeared until the late '50s, when Maytag reintroduced it.

The truth of the matter is, with lots of debate going on over this, hot water didn't come along till the early 1970's. Before then, it was merely warm water.LOL.

hot water

I hope you are joking about the hot water. I definitely remember billowing clouds of steam coming out of the handle in the '54 Unimatic when it was set to hot...only other choice was warm..
