Disaster Averted (the Saga Continues)

I'm washing my hands of the surplice today, so this morning I took it down to the laundry room to stick it in the washtub and just wash to whole thing with Woolite before I iron and starch it. I turned the water on and waited for it to get warm. While I was waiting, I noticed that something didn't look quite right. Sure enough, as I watched, the water slowly turned bright orange and then back again. Needless to say, I took the surpice back upstairs and spot-cleaned it with distilled water. $@^$ South Bend water.
