The short answer
How Hydroxyl Treatment Works
Hydroxyl treatment generates hydroxyl radicals, which are molecules that react with and break apart odor-causing compounds. Think of it as a controlled oxidation process that changes the chemical structure of the odor source, turning it into harmless byproducts like water and carbon dioxide. This is different from masking smells with fragrances.
The treatment is applied as a fine fog or mist that can penetrate porous materials like drywall, wood, and fabric. That means it can reach odors trapped deep in your home's structure, not just on surfaces. It's a popular choice after water damage because it also helps reduce mold and mildew odors at the source.
When You Might Need It
After a flood, leak, or sewer backup, lingering odors can be stubborn. Even after water is removed and materials are dried, smells can persist. Hydroxyl treatment is often used when the odor is widespread or has soaked into porous surfaces. It's also useful for smoke odors, though that's a different situation.
Humid climates can make musty smells worse, especially after water damage. The treatment can be part of a broader cleanup that includes removing wet materials and drying the structure. It's not a substitute for removing water-damaged items, but it can help with the final odor removal.
- Water damage from floods or leaks
- Sewage or backup odors
- Mold and mildew smells
- Smoke odors from fire (as part of professional cleanup)
- Pet odors that have soaked into flooring or walls
What to Expect During Treatment
During hydroxyl treatment, the pros will set up equipment that generates the hydroxyl fog. You'll likely need to leave the area for a few hours, as the fog can be irritating if inhaled. The pros will seal off the room or area to contain the fog and let it work.
The process can take several hours, depending on the size of the space and the severity of the odor. Afterward, you may need to air out the space. The pros will also address the source of the moisture, because hydroxyl treatment alone won't stop a leak or dry out saturated materials.
Is Hydroxyl Treatment Safe?
Hydroxyl treatment is generally considered safe for most homes because it doesn't use harsh chemicals. It's similar to what happens naturally in the atmosphere when sunlight reacts with pollutants. However, it's not something you should try to do yourself with homemade devices; it requires specialized equipment and knowledge.
The pros will take precautions, like ensuring the area is ventilated after treatment and advising you when it's safe to re-enter. If you have respiratory conditions or concerns, mention that to the pros. They can adjust their approach. As with any treatment, follow their guidance for your safety.
When to Call the Pros
You might consider calling the pros if you have persistent odors after water damage, especially if you've already cleaned and dried the area. They can assess the situation and determine if hydroxyl treatment is appropriate. They also have the equipment to do it effectively.
The pros can also help with the underlying issues, like removing wet insulation or flooring that may be harboring odors. They'll work with you to identify the source and recommend the right steps. Remember, hydroxyl treatment is one tool in a larger odor removal process.
- Odors persist after cleaning and drying
- You have mold or mildew growth
- Water damage affected porous materials
- You want an approach that avoids harsh chemicals

Does hydroxyl treatment remove mold?
Hydroxyl treatment can help reduce mold and mildew odors, but it doesn't kill mold on surfaces. The pros will clean visible mold first and may use antimicrobial treatments. For active mold growth, you need a mold professional who can safely remove contaminated materials.
How long does hydroxyl treatment take?
A typical treatment session can last from a few hours to a full day, depending on the area size and odor severity. The pros will give you a time frame after assessing your home. You'll need to stay out during the treatment and possibly for a short time afterward.
Can I do hydroxyl treatment myself?
No, hydroxyl treatment requires specialized equipment that generates the hydroxyl radicals safely. DIY methods aren't effective and could be unsafe. It's sensible to have the pros handle it, as they can also address the underlying moisture issues that cause odors.
