Carpets and upholstery are the main dirt reservoirs in a room. Textile fibers absorb dust, fungal spores, bacteria, skin particles, sweat and spills. Over time a characteristic musty odor forms that vacuuming or even dry cleaning cannot remove.
Dry cleaning removes dirt and stains but does not always handle deep odors and microorganisms in the material. Ozonation is the ideal complement, providing full deodorization and disinfection after wet cleaning.
What is treated with ozone
- Carpets and carpeting — floor, wall, hand-made
- Upholstered furniture — sofas, armchairs, poufs, benches
- Mattresses and pillows — including orthopedic
- Curtains and drapes — without removing from the rail
- Soft toys — safe for children's items
- Car seats — as a separate service
Textile ozonation methods
There are two main methods: whole-room treatment and local chamber treatment of a specific item.
Comparison of textile ozonation methods
| Parameter | Room treatment | Chamber treatment |
|---|---|---|
| Scope | All textile surfaces at once | Single item of furniture/carpet |
| Ozone concentration | 20-40 mg/m³ | 40-80 mg/m³ |
| Treatment time | 4-8 hours | 2-4 hours |
| Ozone consumption | High (large volume) | Low (small volume) |
| Effectiveness | Uniform | Maximum locally |
| When to use | General room deodorization | Strong local odor |
Chamber treatment technique
Item preparation
If needed, do preliminary dry cleaning or vacuuming. Allow to dry completely. Lightly mist the surface with a sprayer to activate soiling.
Creating the chamber
Cover the item with plastic film. Seal the edges to the floor to form an airtight "chamber". Leave a small opening for the ozone generator hose.
Connecting the generator
Insert the hose under the film. Secure so ozone does not escape. Turn on the generator. The film should inflate slightly from the gas flow.
Exposure
Hold for 2-4 hours depending on odor intensity. For heavy soiling — up to 8 hours. You can turn pillows periodically for even treatment.
Finishing
Turn off the generator. Remove the film. Ventilate the item for 30-60 minutes. Ozone fully decays, leaving no trace.
Ozonation after dry cleaning
Ozonation is the ideal final step of professional dry cleaning:
- Removes odor of chemicals used in cleaning
- Kills bacteria that may remain after wet treatment
- Eliminates deep odors that dry cleaning did not remove
- Prevents mold in damp spots
- Deactivates allergens (mites, spores, pollen)
- Increases perceived value of the dry cleaning service
| Step | Action | Result |
|---|---|---|
| 1. Dry cleaning | Removal of dust, hair, large debris | Preparation for wet treatment |
| 2. Wet cleaning | Removal of stains and soiling | Clean surface |
| 3. Drying | Drying to 10-15% moisture | Mold prevention |
| 4. Ozonation | Deodorization and disinfection | Fresh smell, germs eliminated |
Ozonation after flooding
Flooding is a special case requiring quick action. Wet textiles are an ideal environment for mold. Ozonation prevents it:
- First dry carpets and furniture as much as possible (dehumidifiers, fans)
- Residual moisture should not exceed 15-20%
- Run ozonation at the first signs of musty odor
- Ozone concentration: 40-60 mg/m³ for mold prevention
- Treatment time: 6-12 hours for full disinfection
- If mold is found — treat with inhibitor before ozonation
Benefits for cleaning companies
Higher average ticket
Ozonation after dry cleaning adds 30-50% to the service price
Handling difficult cases
Odors that dry cleaning cannot remove are eliminated by ozone
Fast payback
Generator pays for itself in 1-2 months with regular use
Competitive edge
Not all dry cleaners offer ozonation — stand out on the market
Recommended treatment modes
| Item type | Method | Concentration | Time |
|---|---|---|---|
| Carpet (light odor) | Room | 20-30 mg/m³ | 4-6 hours |
| Carpet (strong odor) | Chamber | 40-60 mg/m³ | 4-8 hours |
| Sofa | Chamber | 40-60 mg/m³ | 3-4 hours |
| Mattress | Chamber | 30-50 mg/m³ | 2-4 hours |
| Curtains (on rail) | Room | 20-40 mg/m³ | 4-6 hours |
| Soft toys | Chamber (in bag) | 30-40 mg/m³ | 1-2 hours |
Safety for materials
Ozone is safe for most textile materials when recommended concentrations are followed:
- Natural fabrics (cotton, linen, wool) — safe
- Synthetic fabrics (polyester, nylon) — safe
- Natural leather — safe, but conditioning afterward is recommended
- Latex and rubber — long treatment at high concentrations not recommended
- Dyed fabrics — safe, ozone does not bleach at recommended settings
- Delicate fabrics (silk, viscose) — safe at standard concentrations
