Shelly, I pretty much agree with all the advice you have received. As I'm not sure of that, I decided to Google "Batteries in the washing machine" to see what came up. There are many links, but a post in this one made this suggestion:
"I would call the poision control center and see what they can tell you: 1-800-222-1222"
The person did and this was the response:
"Thanks. I just called and I was told to wash the clothes a couple times, and they should be safe and that the problem is that the alkaline in the battery can cause a burn, but after washing the clothes a few times, it should get out and be safe to wear."
It's funny, most of the people were worried whether or not the batteries were still good and not about the clothes or washer.
