Bit, although I do use the "steam" cycle in our new washer, we just used the regular wash cycle before... I think I'd recommend warm water rather than cold, maybe even hot if your clothing can handle it... pretty sure mom just washed in warm, cold water rinse, normal detergent with maybe just a splash extra for good measure.
Melissa, that's not nuts. For years, I was virtually immune thanks to a series of allergy "desensitization" shots. They sure worked for me, guess they didn't work for enough people though or there were other issues... they stopped making the booster shots (basically poison ivy serum), and eventually my sensitivity returned. Boo hisss. I never had the nerve to inject or ingest anything on my own!
