So I've had a throat injury and also severe Laryngitis. Went to the doctor who gave me meds, and also several suggestions, one of which was to use a humidifier. I don't own one, but I had one once and emptying it and cleaning it was annoying. So I decided to go the old fashioned way, and put a huge pot of water on simmer on my stove and let the steam put moisture into the air. So I've had it on the stove steaming all day yesterday and today, shutting it off of course when I go to sleep. I live in tiny cottage, so it didn't take long for all my windows and everything else in sight to steam up and get condensation. Then today I decided to add a small clip-on fan to the kitchen, to push some of the steam out of the kitchen and into the other rooms. As I was looking around for a place to clip it, I discovered brown liquid dripping from my window edges, ceiling vent, recessed lighting, etc. Just gross brown drips, everywhere. I immediately thought of nicotine, having cleaned out my mother's house after years of her smoking, and I remember wiping BROWN off every surface. When I bought this house last year I didn't notice any of this brown residue, and didn't smell any signs of the former owners being smokers. So I'm not sure if there were smokers here before me, and only now, due to all the steam is it surfacing, or if it's just dirt?! Although it's a very yellow-ish brown, so I'm suspecting nicotine. So, just thought I'd share that not only am I getting lots of moisture for my throat and house plants, I'm also doing a bit of early spring cleaning running around like a lunatic with paper towels wiping off brown drippings from everything! LOVELY.
