I have a plum-pudding scented candle in the kitchen that I still haven’t tried lighting.
Unlikely, but true!
Filthy drawers? Dead mouse? So that’s what turns you on? Gee, you people are strange… 
Me, I’d go for:
Salty sea breeze.
The vague, yet distinct, smell of air at -35 C.
Egg Salad Sandwich Fart
Unflushed Toilet in 90F Weather
Moldy Clothes
Rancid Milk
Stale Pizza
Garbage Disposal
Bleach
Ginger Ale Barf.
(2trew- I think a Play-Doh candle would be cool!)
Dunno if anyone uses this copying process any longer, but:
Mimeograph fluid

Apples ‘n’ meat
Berries ‘n’ bleach
Pickles ‘n’ gasoline
Fudge ‘n’ carcass
Wildflowers ‘n’ whiskey
Cucumber ‘n’ Napalm
Cinnamon ‘n’ sulfer
Citrus ‘n’ horse

Cat anal gland leakage
Dammit! I was hoping no one else would think of that:)

Urinal Puck
Burning tires
Morning breath

Whatever the dog rolled in before getting in bed with you.
Pig farm
mouse tinkle
Spaghetti sauce spill on a red hot burner
Party-house carpet on a hot, humid day
Italian sausage belches
Burnt-up electrical motor
jalapeno vomit
I always thought of that as a fresh smell, once my nostrils managed to open. Maybe you were smelling the inside of your nostrils once they slammed shut.

I have a Sweaty Feet scented candle that my niece gave me for Christmas. I lit it once, and it lives up to billing.
leaky battery
hot tar in 100% humidity in August
rubber cement

the smell inside stores that make their own glasses - Pearl Vision and such - they smell awful!!!
