S/O of sorts. What smells remind you of your childhood?

Pine sawdust (my dad was a carpenter/furniture maker) and Comet Cleanser (my mom sprinkled it liberally in cleaning).

Nivea face cream - my nana
Dettol (antiseptic) - throwing up into a TipTop icecream container and/or skinned knees
Vicks vapor rub - my endless colds (if only they'd realized they were actually allergies!)
Sunlight soap - washing dishes
coconut suntan oil/certain sunscreens - kiwi summers at the beach
a particular scent of fake pina colada - the lipgloss I used when I was 11-12, sitting on the hot asphalt at school, the boy I had a crush on.
rotten fish - my poppa (the fisherman. One time he had a giant stingray he'd caught by accident rotting on the back lawn. He would dig all the nasty fish guts and waste into his garden - made for the best bean crops).

Great question. For me it would be:

Old Spice - my father used to use this and it always lingered in the bathroom where my sister knocked over a bottle of it and it soaked into the tile grout. It remained throughout my childhood and was there when we sold that house. Someone gave him something else and he didn't use Old Spice anymore. I loved it.

Night blooming Jasmine that grew over the arch entry to Granny's yard.

Crayons

Play dough

Chanel No. 5 - my mother used to wear this when we were really young and she and dad were going out dancing. When the bottle ran out, she never replaced it. As a child, I wondered why a tv channel would have a perfume and what the other channels smelled like.

I don't know how to describe this, but there was a certain smell in my father's supply room at his company. He owned a building materials business and the smell of the supplies, pads of invoice paper, rolls of adding machine tape, and boxes of mystery items mixed with the smell of the cement sacks that were in the big sales area. I would go in there to get pads of paper to draw with when my sisters and I spent a Saturday there with him. Where I live now, there was a big office supply store, mom and pop store, not Office Depot type, that has recently closed down. They were in a warehouse building. The front of the store was set up like a nice store, and the rear of the store was their storage area. They used some of the warehouse shelves as priced merchandise and others were their restock for the front of the store so you could go back and wander through the big tall supply shelves. Back in among those warehouse shelves, with its dusty cement floor, stacks of paper pads, and boxes cut open so you could purchase from them, I could catch whiffs that took me back to all those Saturdays spent in my dad's supply room.

Wet pavement, but not all kinds, just the porous kind.
The smell of fire/smoke combined with a wet dog smell reminds me of the small Mexico towns we would visit during summer break.

My grandmother always smelled of bourbon and Oil of Olay.

I love the smell of cut grass.

The smell of a horse can take me back to the barn and our horse we had when I was 8.

Rubbing alcohol because my dad used it on bug bites.

Ban de Soleil. We used to go to the beach all the time when I was a kid.

And not so pleasantly the smell of bodegas (corner stores). When I was a kid there was one two blocks away called Elly's that was the first store I was allowe to walk to by myself. Not a good smell, but all bodegas smell exactly the same. Every time I go into one I think of being a kid in Brooklyn.

Mac and cheese - I went to preschool and they served this to us all the time.

Mennen skin bracer after shave - my dad used this.

Pine Sol - my mom used this to clean the floors.

Hmm, Jergen's original cherry almond hand lotion and Chanel No.5 remind me of my mother. Pipe tobacco reminds me of my Uncle and Pop (my dad's brother and father). Moth balls and cigarette smoke remind me of Nannie and Grandpa's house in Queens, NY. Also jet fuel, they lived near JFK. Coffee and cat food remind me of my Aunt and Uncle's house. You walked into their tiny carpeted kitchen and that warm smell combo was prominent, but not unpleasant. Of course, Coppertone is an instant Robert Moses/Jones Beach childhood memory. And the electrical burning rubber odor from bumper car rides takes me back to Adventureland on Long Island. A warm waft of honeysuckle is a sweet summer reminder of my LI neighborhood growing up. I'm sure I'll think of more after I post this lol.

Freshly cut pine wood. My Grandpa owned a woodworking company so the scent was always there.

Copper tone and seaweed. Super cold dry refrigerated air, we used to open the door on old school coke machines and breathe in that cool air on hot summer days.

Thank you whoever mentioned Emeraude, I couldn't remember the name. Mom wore it a lot. Sawdust reminds me of dad. Clothes dried on the line. Freshly mowed grass. Mom's pot roast. My grandparents house had its own clean smell that I can't describe.

Smells and music are powerful memories

Jean Nate and whatever pressed powder my grandmother used.

The tobacco my father used in his pipe.

The smell of (what I considered to be) overripe bananas in my grandmother's cabinet, and the smell of the vitamins and candy she kept in her hutch.

The smell of a cookie tin full of crayons. Lilacs & lily-of-the-valley. Grapes ripe on the vine.

Sun tan lotion that smelled like coconuts. The sea air.

My other grandmother's kitchen smelled like some sort of mix of dish soap and cigarette smoke, mixed with the floral smells coming in the windows, and yet for as disgusting as that sounds, I always loved the smell of her kitchen. And her pantry and basement had their own smells, too. My aunts, who live in my great and great-great grandfather's home have an attic with a smell I can describe, but which I adore.

Pot roast and italian dressing, which were the 2 prominent smells every Saturday night. Homemade tomato sauce. Garlic & basil & pecorino romano cheese.

Chlorine. From our own pool, and far stronger in the school pool where we took lessons as kids.

Cream soda. Matza ball soup.

Leaves in the fall. Apples from the huge tree in our backyard.

Boo, Hiss to the cancer.  Hooray for the Prell and iodine.

Lilacs, my mom and dad have a lilac bush by their bedroom window.

Obsession for men. It was my LH's cologne when we first met.

Brut, my dad's Cologne.

Banana bread in the oven.

Fresh cut grass.

So many scents take me back to special memories.
