Well, I got the ammonia. Wow, is that stuff cheap. I looked for plain 'ol ammonia, but had to settle for lemon scented. So while sitting down, I cracked it and figured I'd give her a wiff to check out the lemon smell. Nothing lemon there, but I can now breathe easily through my nose as it is no longer plugged! Lesson learned, read the warnings..... But gonna mix a batch of cleaner up today and giv'er a try. Thanks again all.
