This issue comes up often when comparing cleaning techniques. For example when comparing chemical use and duration to rapid clean steam.
Bleach often contains Sodium Hypochlorite — Sodium hypochlorite can cause severe eye irritation and if ingested can cause severe stomach irritation and sores. Sodium Hydroxide is also often used to stabilize household bleach. It is extremely caustic and can cause significant skin irritation if touched.
Other simple cleaners contains trace doses of 2-butoxyethanol — sustained inhalation of high concentrations (100-500 ppm) of this compound has been found to cause adrenal tumors in tested animals. Please consult toxicologists for a definitive analysis.
An non-intuitive feature of using chemicals over steam is noted in the energy usage. See for example (click).
