The Theory

Every cleaning product on the shelf smells like pine, lemon, or lavender.

None of them belong in your house.

Theory is a theory about what a home should smell like when it is, in fact, clean.

Why Theory

Walk down any cleaning aisle. Pine. Lemon. Lavender. Bleach. The same five fragrances dressed in slightly different bottles, designed for someone who doesn't exist.

A home should smell like the person who lives there. Not a hospital. Not a citrus grove. Not someone's grandmother's linen closet.

Theory makes the products you already buy — surface cleaners, odor eliminators, the things under your sink — formulated to actually work, scented like something you'd choose if anyone bothered to ask you.

Three scents, built around moments. The bar at the back of a hotel. The woods after rain. A barbershop that's been open since 1962.

That's the theory.

Three Scents. One Theory.
No. 01
Cedar &
Bourbon
Aged oak, warm spice, the back room of a place worth remembering.

Oak Moss &
Vetiver
Damp earth, green shadow, the woods after rain. Quiet, not clean.
No. 03
Bay Rum &
Clove
Old-school barbershop. Warm, dry, slightly smoke. The good kind of nostalgia.

I started Theory because every cleaner on the shelf was either pine, lemon, or lavender. None of them belonged in my house. So we built three that did.
