When multiple chemicals are applied to the same surface without full removal of the earlier substance, the chemicals may interact. This interaction may reduce the efficiency of the chemicals applied (such as a change in pH value caused by mixing alkalis and acids) and in some cases may even emit toxic fumes. An example of this is the mixing of ammonia-based cleaners (or acid-based cleaners) and bleach. This causes the production of chloramines that volatilize (become gaseous), causing acute inflammation of the lungs (toxic pneumonia), long-term respiratory damage, and potential death.

Residue from cleaning products and cleaning activity (dusting, vacuuming, sweeping) has been shown to worsen indoor air quality (IAQ) by redistributing particulate matter (dust, dirt, human skin cells, organic matter, animal dander, particles from combustion, fibers from insulation, pollen, and polycyclic aromatic hydrocarbons) to which gaseous or liquid particles can be adsorbed. The concentration of such particulate matter and chemical residual will highest immediately after cleaning, and will decrease over time depending upon levels of contaminants, air exchange rate, and other sources of chemical residual.[5] Of most concern are the family of chemicals called VOCs such as formaldehyde, toluene, and limonene.
Volatile organic compounds (VOCs) are released from many household cleaning products such as disinfectants, polishes, floor waxes, air-freshening sprays, all-purpose cleaning sprays, and glass cleaner. These products have been shown to emit irritating vapors. VOCs tend to evaporate and then to be inhaled into the lungs or adsorbed by dust, which can also be inhaled. Aerosolized (spray) cleaning products are important risk factors and may aggravate symptoms of adult asthma, respiratory irritation, childhood asthma, wheeze, bronchitis, and allergy.
Other modes of exposure to potentially harmful household cleaning chemicals include absorption through the skin (dermis), accidental ingestion, and accidental splashing into the eyes. Products for the application and safe use of the chemicals are also available, such as nylon scrub sponges and rubber gloves. It is up to consumers to keep themselves safe while using these chemicals. Reading and understanding the labels is important.
Chemicals used for cleaning toilets, sinks, and bathtubs can find their way into sewage water and can often not be effectively removed or filtered.
There is a growing consumer and governmental interest in natural cleaning products and green cleaning methods. The use of nontoxic household chemicals is growing as consumers become more informed about the health effects of many household chemicals, and municipalities are having to deal with the expensive disposal of household hazardous waste (HHW).
