Hi, I react to some fabric too. I wash them once on a normal cycle with warm water and detergent. Then I put them in the dryer and take them out when they are still damp to be ironed. Sorry. Hassle. I do not serge or do anything to the edges. I just trim the extra loose threads and often get help from one of my daughters with the trimming. You can also lay them on a cutting baord and lay a ruler on the edge and trim all the loose threads that way.
