I took everything out of the dryer and shook the clothes to get the matches out.
I then looked at the clothes and found little red dots all over them (from the red tip of the matches)
My favorite sweater was covered in red dots. I took the sweater and put it back in the washer. I washed it in HOT water. When the cycle was done, I very nervously took the sweater out...and...it was back to normal! No red dots! Yay!
However, it was late when I started rewashing the sweater and I was too lazy to inspect every item in the original load, so I just left the rest. Now I have underwear and dish towels with red dots all over them. Since they've already been through the dryer, I don't think there's much hope. Fortunately, the rest of the clothes in the load were black, so it doesn't show. Though I guess we will be walking around with match-tip residue on our clothes. Is that bad?
