I went through something similar (not soaping stuff, but wood and other various possessions) where I had to decide what I could clean and disinfect and what to throw away. I did just as lenarenee suggested with the bleach solution and sun-drying. As a CPR instructor, one of my duties was to clean and disinfect the training equipment after each training session. What we used per CDC (Center for Disease Control) guidelines was a 10% bleach solution with a (if I remember correctly, it's been a very long time ago now) 10 minute soak for the most-likely to be the most contaminated parts, and then air dry. So with that in mind, I proceeded with cleaning my personal possessions attacked by that mouse infestation.
It was disgusting handling some of the items and some things I just tossed because I wasn't sure I'd ever really get over the idea of or memory of the mice urinating on my stuff. But a couple of wooden dressers & other furniture items I just did not want to toss. So I disinfected them and left them in the sun to dry. If they smelled okay to my nose (which is rather sensitive and was even more so back then) I lined the drawers of a dresser and carried on. If, however the inside of the dresser drawer looked badly stained and still smelled bad, I just got rid of the whole thing.
In my 20's I had another mouse-in-the-drawers experience that looking back on it now is pretty funny. I had cats and dogs, too, so it really surprised me when one day I opened a drawer in my pantry where I kept extra linens and found a momma mouse had given birth to a bunch of baby mouse on my linens. It must have just happened because they were all slimy and tiny. I was absolutely horrified of course. For the life of me, I just don't remember how I managed to get the mice out of the drawer and the house and what I did with them. But I removed the drawer and cleaned and disinfected it and put it back to service in my pantry again. I probably called my mom for suggestions about how to disinfect it because I wasn't yet trained as a nurse, although I could have been in nursing school already. I may have even cleaned it with lye. That's what I used to clean my oven & stove parts in those days. (I had an old fashioned O'Keefe & Merritt stove that came apart easily and my mom taught me to soak the parts in lye solution in my utility sink to clean them. It worked like a dream.)
The moral of the story is decades later since both incidents, neither I nor my family ever contracted any diseases from coming in contact with the items I disinfected and continued to use after those invasive mouse infestations. I still actually have one of those dressers I spoke of, and even have and used for a long time some of those linens from over 40 years ago.
