Rule of thumb: work fresh
Ozone dissolved in water does not stay active indefinitely. A practical rule of thumb is that ozone water is strongest right after production and that effectiveness often drops noticeably within about 15–30 minutes. That’s why on-demand use is usually the most predictable.
Plan your round without stock
Produce smaller amounts and use them immediately per room or section.
Keep a fixed order: touch points → work surfaces → wet zones.
Use the two-cloth method for a consistent finish.
What influences timing?
Temperature and agitation can influence how quickly ozone declines in water. Warmer water and heavy turbulence may speed it up. For teams, a calm routine and avoiding over-wetting keeps results more consistent.
