What is the difference between cleaning, disinfecting and sanitizing?

Often times when it comes to the words clean, sanitize and disinfect they are used interchangeably. However, there is a significant difference between these terms and knowing what they mean can help keep your home or workplace a clean and safe environment.

Cleaning physically removes germs, dirt and impurities from surfaces or objects. It involves using soap or detergent and water along with a mechanical action such as wiping to remove germs from surfaces. Cleaning does not kill germs, but by removing them, it lowers their numbers and the risk of spreading infection.

Disinfecting kills germs on surfaces or objects. In order to kill germs properly, chemicals need to be applied according to the label as each product is different. Disinfecting does not necessarily clean dirty surfaces or remove germs, but by killing germs on a surface after cleaning, it can further lower the risk of spreading infection.

Sanitizing lowers the number of germs on surfaces or objects to a safe level, as judged by public health standards or requirements. In order for a product to be considered a sanitizer, it must reduce bacteria on a surface by at least 99.9 percent. This process works by either cleaning or disinfecting surfaces or objects to lower the risk of spreading infection.

Why did the technician leave wet carpet on my stairs?

After water damage in your home, stair carpeting is generally not removed for safety reasons. Exposed tack strips or staples, especially on steps, can be dangerous. However, there are situations where removing carpet from stairs is necessary to prevent damage to hardwood steps underneath, or in the case of sewage contamination. Removing tack strips is not advised, as this may damage the hardwood or the subfloor. Extreme caution must be used whenever the tack strip is exposed or when the carpeted stairs are damp. If carpet left on the stairs is unsalvageable, it will be removed when new carpet is installed.

What is black mold?

Black mold (Statchybotrys chartarum) is greenish-black in colour and grows in conditions where there is an excessive amount of moisture over a long period of time. Water damage, excessive humidity, water leaks and condensation in small, damp places like bathrooms all create a perfect breeding ground for black mold. Black mold releases microtoxins, a noxious substance that can cause serious health problems for humans and pets.
