Yesterday I was doing the laundry, and I was putting the clothes from the washer to the dryer. I noticed a fuzzy thing on the bottom of the washer, it was a dead mouse. There was no blood, but I just can't pray with that image in my head. I washed it again after taking out the mouse but I'm still not satisfied. I wish I can just throw all the clothes and the washer away…but I can't. Please Help me. Jazakallah.
What you are doing is wrong. the clothes are clean, once you have washed them by hands 3 times and squeezed out however much water you can each time (or washed them in the washing machine, which does the washing and squeezing for you).
thus, you should wear them.
If, however, you still find it difficult to wear them, then do not throw them away. rather, wash them, then put them in a clothes bank, so that a poor person can wear them.
