Here's some background:
We bought this house in July of 2017. The previous owner left a hall closet full of GNC-style product (it was packed with pills of all kinds). It primarily smells of those heavy iron supplement type of odor if you can imagine. We called our realtor, and he came and emptied it.
To our unpleasant suprise, the closet smelled like the products a month after it was emptied.
It is now December of 2019 and it still smells, it's at least tolerable but that is hard to say, especially when any towel brought out of it carries the smell, or walking past the door in the hallway (with it closed) you can catch a whiff.
The house was built in 1986. It is a Ranch. The closet door is a solid closet builder door, with a dark stain and coating.
What We've Tried:
- First Month with nothing in it: Vaccuum and bleach, as well as Lysol.
- Washed down all walls, ceiling, woodwork, and shelves.
- Soap and water, bleach treatment two, dried, and began using the closet for items such as linens and toilet paper
- Tolerated the smell for 6-9 months.
- Emptied the closet, and re-did #1 above.
- Used Simple Green as in #2.
- Washed all linens and put back in closet.
- Tolerated the smell for about another ~9-10 months.
- Re-did #5.
- Removed all shelves and painted the enitre closet. Ceiling, Walls, and the shelves, as well as the woodwork securing the shelves.
- Used Pine-sol on the Door and Door Frame & Trim.
- Re-did #7 & added Cedar cut-outs.
- It smelled more of dried paint for a few days-weeks, but still had an odor of vitamins.
- Tolerated it for another ~9 months and here we are....
I've considered ripping out the drywall. Is this where I am now? Should I buy Killz and go at it again or is such an approach a waste of time? Can I seal it or lock it out? Can I neutralize it, if so, with what chemical? I'm not asking for a product recommendation per-se, but any approach or solution you may have some experience with I'll give it a shot.
I've considered that it isn't the walls or shelves at all at this point *(since they are painted). I have considered it may be the DOOR & Framing, or the wood the framing is mounted to breathing into the space.
The closet has no ventilation outside of the DOOR entry points, which the smell is ONLY in the closet. It is not in the hall. Do I have to remove the door framing and replace it or do something to it, or is it actually still able to breath through the acrylic paint?
