Use it for: the full cabin air reset. Smoke, mildew, pet odour, food smells and used car funk in the airspace, vents and HVAC system. Fill the jar to the line with water, sit it in the cupholder, drop the tablet in, hop out and leave the cabin fully sealed. One kit treats one vehicle, and it's used with the Oxygenator Aerator to cut a treatment that can otherwise run from 2 hours to overnight down to around one hour, while pushing the gas deeper into vents and tight spaces.

Not for: odours soaked deep into fabric and seat foam on its own, that needs Minis and a steamer or extractor first. Never sit in the vehicle during treatment, never run it with a window cracked, and always air the cabin out for 5 to 10 minutes afterwards before driving, longer if you're sensitive to the light chlorine smell.

Use it for: surface and subsurface odours. One dissolvable tablet makes roughly 950ml of cleaning and deodorising solution for a spray bottle, steamer or extractor, working ClO2 directly into carpet, fabric seats, mats and boot lining. A steamer is the preferred tool, with an extractor a close second, because heat and pressure drive the solution into the places traditional cleaning can't reach: carpet padding, seat foam, vents, the headliner and visors. You can also dissolve a tablet into your favourite all purpose cleaner to add deodorising power to it. This is the step that fixes what the gas can't reach, and it's non-negotiable on heavy smoke or pet jobs.

Not for: treating the cabin airspace or vents, that's the VDK's job. The two are partners, not substitutes: Minis handle surfaces, the kit handles air. Skip Minis on glass too, it streaks, use a dedicated glass cleaner there.

Use it for: supercharging a Deodorization Kit. The pump accelerates the ClO2 release and pushes it deeper into vents, cracks and tight spaces, cutting a treatment that can otherwise take anywhere from 2 hours to overnight down to around one hour. Runs on two AA batteries (included) with over 20 hours of runtime, so it'll see out plenty of treatments.

Not for: use on its own. It's an accelerator for the kit, not a treatment on its own. Without a tablet working away in the jar it's just a pump blowing bubbles.

Use it for: long-lasting fragrance after the odour is gone. Made with commercial grade essential oils and deodorants, a bar lasts 60 plus days. Chuck it under a seat or in the console for a clean scent that keeps a treated car smelling the way it should. The mesh storage baggies keep the bar contained and easy to move between cars.

Not for: fixing an odour. Hanging a freshener over a smell you haven't treated is exactly the masking caper Bio-Bombs exists to replace. Get rid of the smell first, then make it smell nice.

Use it for: an instant hit of fragrance on demand, in the car, on mats, or as the finishing touch handing a detailed car back to a customer.

Not for: the same thing no spray freshener is for: covering an untreated odour. It always comes back. Sort it properly with the kit and Minis, then use Fresh AF to keep it pleasant.

Do this: the full combo. Smoke penetrates everything, so treat fabric, carpet and seats with Minis first, then run the VDK with the Oxygenator to reach the vents and headliner airspace. A car that's copped years of heavy smoking may take a second gas treatment, that's normal, not a fault.

Watch out: never soak a headliner with any liquid, the adhesive lets go and it sags. A steamer is the safe way to treat a headliner and visors, otherwise mist lightly at most and let the gas do the headliner work.

Do this: vacuum the hair out properly first, the hair is holding half the smell. Then Minis through an extractor or steamer on seats and carpet, and a VDK treatment to reset the cabin air.

Do this: find the exact spot and treat it directly with Minis solution, extraction is best. Urine sits deep in fabric and foam, so this is a liquid job first and foremost. Follow with the VDK for whatever made it into the air.

Watch out: gas alone will not fix urine. Skip the direct treatment and the smell will be back the next humid day, guaranteed.

Do this: find and fix the water source first, a leaking seal, blocked sunroof drain or wet carpet underlay, and dry the car out completely. Then Minis on affected surfaces and a VDK treatment for the air and vents. Note Bio-Bombs eliminates the odours associated with mould and stale air, it's an odour treatment, not a mould remediation product.

Watch out: treating the smell without fixing the leak just books you in to do it all again. Damp comes back, mould comes back.

Do this: physically remove as much of the spill as possible, spilt milk especially needs extracting from the carpet, not just deodorising. Minis on the spot, then a VDK treatment if the whole cabin has taken on the smell.

Do this: full physical clean-up first, then Minis via extractor on the affected area and surrounds, then the VDK. Rotten job, very fixable.

Do this: fuel is one of the tougher smells to shift. Thoroughly clean the affected carpet with an all purpose cleaner and Minis solution, ideally through an extractor or steamer, and follow with a VDK treatment if the smell has spread through the cabin.

Do this: usually the easiest fix on this list. Get the source out of the car, hit the boot carpet with Minis if the smell has settled in, and one VDK treatment normally knocks it over.

Do this: vape leaves a film on glass and surfaces as well as a smell in the air. Wipe interior surfaces and glass down first, then run the VDK with the Oxygenator for the air and vents.

Do this: bought a used car the dealer has doused in something scented? If the fragrance has soaked into carpet and seats, run Minis through a steamer to get into areas normal cleaning can't reach, then a VDK if any smell persists in the air.

Do this: just bought a car with someone else's smell in it? A vacuum, an interior wipe-down and a VDK with the Oxygenator is the one-hour reset. Add Minis on the seats and carpet if the previous owner's story was more colourful.
