TL;DR
Dwell time is the period a chemical must stay wet and in contact with a surface to do its job — the soft-wash mix sitting on siding, a deck stripper softening old finish, or a disinfectant meeting its label kill time. Product labels state the minimum, often 5 to 15 minutes, and rinsing early is the most common reason a treatment underperforms.
What it means
Dwell time is the period a chemical must stay wet and in contact with a surface to do its job — the soft-wash mix sitting on siding, a deck stripper softening old finish, or a disinfectant meeting its label kill time. Product labels state the minimum, often 5 to 15 minutes, and rinsing early is the most common reason a treatment underperforms. Hot sun shortens working time by drying the solution, so pros mist surfaces to keep chemistry active.
