Why does my house smell and I can't find it?
First, accept the humbling science: you cannot smell your own house. Olfactory adaptation tunes out constant background odors within minutes, which is why your home has a smell every guest notices and you never will. Step outside for twenty minutes, come back, and inspect nose-first.
The repeat offenders hide in water fixtures. A floor drain or rarely used sink whose U-shaped trap has dried out lets sewer gas straight in; the fix is pouring in a cup of water. The garbage disposal's rubber splash guard grows a film worth scrubbing underneath. Front-load washer door gaskets breed mildew. Beyond plumbing: the vacuum's own bag, a forgotten potato, sponge rot, and anything organic behind or under furniture.
Musty smells that persist after cleaning deserve real attention, since that is the signature of hidden moisture or mold, and finding the leak matters more than masking it.
You have gone nose-blind to your own home; everyone does. The usual hidden culprits: a dried-out drain trap, the garbage disposal splash guard, the washing machine gasket, or something organic behind furniture.
