Why surface treatments don’t hold

The smell isn’t on the surface. It’s in the structure.

Cooking oils aerosolize. The good news is the molecular process behind BIOSWEEP reaches where surface treatments cannot.

The problem

Why cooking smells stay

Cooking oils aerosolize. Microscopic grease and aromatic particles coat every surface in the kitchen and travel down the HVAC into the rest of the home. Spray cleaners and candles cover the surface; the source on the cabinets, drywall, and inside the HVAC ducts keeps releasing the odor.

The fix

How BIOSWEEP treats it

Five-stage photocatalytic oxidation destroys grease and aromatic molecules at the molecular level on every reachable surface simultaneously — including the HVAC system that carries the smell to every other room. The cooking smell is permanently gone, not covered.

How it works

From phone call to permanent result

Most Chicagoland jobs run on the same four-step path. Same-week scheduling is standard.

FAQ

Questions Chicagoland homeowners ask

What kinds of cooking odors does BIOSWEEP work on?

All of them. Curry, fried foods, fish, fryer oil, smoke from cooking, even old refrigerator and freezer odor. The molecular process is the same regardless of the food source.

How long does the treatment take?

Home kitchens are typically a single overnight cycle. Restaurants can usually be treated in one extended off-hours session. We size the BIOSWEEP deployment to the kitchen and adjacent areas.

Do you treat restaurants?

Yes. Treatment is scheduled outside business hours, often on a closed day. We’ve treated cafe and fast-casual kitchens and dining areas across Chicagoland.

Will the treatment affect food prep surfaces?

BIOSWEEP fully dissipates before re-entry. By the time the kitchen reopens, there is no residue or scent from the treatment itself — only the absence of the odor that was there before.

Is this for grease residue too, or just smell?

We’re focused on the odor. Grease residue still needs to be wiped from surfaces by a cleaning crew — BIOSWEEP destroys the molecules that cause the smell, including the ones embedded behind cabinets and inside the HVAC where wiping cannot reach.

Condo or apartment with cooking smell from a neighbor?

Yes. If the odor is traveling through the HVAC or wall cavities, BIOSWEEP can treat your unit specifically. We’ve done this for Chicagoland condo owners and HOA-coordinated projects.
