lol, yup, normal smell of death/decay. I had tried a nep outside one year and its pitchers were filled with wasps. Didn't matter until I brought it inside and it stunk up my apt. Dead insect smell is worse than I thought it would be.

When you let sweaty items made of sandwiched material (bras) sit in the hamper, mildew and bacteria grow in the middle layer and might not get totally washed out. Strongly salty water kills the odor making bacteria/mold so that is probably why it works. A giant bag of salt at Sam's Club is pretty cheap, so that might be your source of salt. It's too bad chlorine bleach is a no-no for bras as that would kill off everything living in the middle layer. I use hot water and oxyclean and it has been enough for me. Maybe I will pay more attention to the supermarket shelves and see if there is some sort of disinfecting additive that can be added to the prewash (assuming that your model lets you put a prewash in front of the delicate cycle). If I had your problem, I would prewash by hand using a little bit of detergent and gently knead the wet mix into the bra's problem areas. It's your choice to knead solely in your hands or knead on top of a sponge for softer kneading of the fabric. Then toss in the wash without rinsing out. If that doesn't work, I would escalate by diluting some mouthwash and using that to kill germs and sterilize. I would experiment to find an economical ratio of water to that brand of mouthwash. Those prior two methods are easy, but if they don't, I'd try using an antibacterial soap and then rinse out most of the soap that comes out easily as I depend on the washer getting rid of the rest of the soap residue. If you have no antibacterial soap or its killing power is too weak, then try head & shoulders shampoo as the next alternative but that will take extra rinsing out since shampoo has fragrance in it. As antibacterial handsoaps go, they range from the weak 0.1% triclosan to the robust 0.3% triclosan (the cheap handsoap in the commercial cleaning products section of Sam's Club).

Now I have a similar problem with the same cabinet, only this time the smell isn't mysterious. It's unmistakably urine. How bad is that!?! Mouse urine? I'm guessing that once again you won't really find anything, and that the bottom of the cabinet should probably be removed to see just how something is getting under it to do its business. In looking around outside, do you see any significant cracks in the concrete around the edges? I've always heard though that there are but 2 kinds of concrete...Concrete that's cracked, and concrete that is going to crack. You might try asking about the problem at the link below. Good luck. I too have fought critters and smells before and know it is not fun. Here is a link that might be useful: Old Houses Forum

Im sure that by now you have learned that there is a paper mill in counce, and with the right wind direction, we also get the smell in finger, tn (mcnairy county)
