Koch Chemie Fresh Up is a professional odor eliminator and vehicle deodorizer that neutralizes unpleasant smells at the molecular level rather than simply covering them with fragrance. The formula encapsulates odor molecules from smoke, pets, organic sources, food, and mustiness and eliminates them, leaving behind a genuinely fresh-smelling interior that customers will notice the moment they get in the vehicle.

Safe for use on all interior surfaces and textiles including fabric seats, carpet, headliners, and door panels. Also works in boats, caravans, motorhomes, and indoor spaces where persistent odors are a problem. Fast-acting and easy to apply by spray, making it a practical addition to any interior detail or odor removal service.

If you are looking for a professional automotive odor eliminator that truly neutralizes smells rather than masking them, a Koch Chemie deodorizer for car interiors, or a sprayable odor treatment for smoke and pet odors in vehicles, Koch Chemie Fresh Up is a trusted product for professional detailers who want reliable odor control results. Available in 1L.

Koch Chemie Fresh Up Usage

Fresh Up is Koch Chemie's professional odor eliminator — an enzymatic odor-neutralizing product that removes smoke, food, pet, and musty odors rather than masking them with fragrance.

• Fabric & upholstery: Mist directly onto affected fabric. Allow to dry naturally.
• HVAC smoke/musty odor: Turn HVAC to recirculate, fan on high, mist into the air intake under the dash. Let the system cycle the product through.
• Dose: Moderate. Fresh Up works with enzymatic action — over-soaking isn't necessary.

Not: A fragrance spray. Fresh Up neutralizes odor molecules at the source. For a scent-forward finish, follow with an air freshener of your choice.

Frequently Asked Questions

Does Koch Chemie Fresh Up actually work on smoke smell?

Yes — and it's one of the top reasons shops buy it. For smoke odor, treat the upholstery and headliner directly, then run the HVAC system on recirculate with Fresh Up misted into the air intake. Enzymatic action neutralizes the odor molecules rather than masking them.

Koch Chemie Fresh Up review — is it worth it?

For professional detail shops doing used-car reconditioning or pet / smoker cars, yes. It's one of the few odor eliminators that works by breaking down odor molecules instead of masking them. The trick is application technique — treat the fabric, treat the HVAC, let it dry naturally.

How do I use Koch Chemie Fresh Up in HVAC?

Turn the HVAC to recirculate, fan on high. Mist Fresh Up into the air intake vent under the glove box or in the engine bay. Close all doors and let the system cycle for 10-15 minutes with no occupants. This distributes the product through the entire air handling system.

Is Koch Chemie Fresh Up safe on leather?

Used as directed (light mist, not saturation), yes. For leather-heavy interiors, keep the mist light and let it dry naturally. Follow with a leather conditioner like Leather Star if the interior feels dry.
