Damage to Appliances and Fixtures

  • SERRATIA MARCESCENS usually found building up in bathrooms especially on tile grout, shower corners, toilet water line, and within the basin. It develops as a slimy film and feeds off phosphorus-containing materials or fatty substances like bath soap and shampoo residue.
  • STAPHYLOCOCCUS AUREUS can cause food poisoning, and skin and bone infections.
  • BURKHOLDERIA CEPACIA is a human pathogen that takes advantage of moist conditions to further its spread. This bacteria is known to cause pneumonia in individuals with impaired immune system with underlying lung disease.
  • PSEUDOMONAS AERUGINOSA can be found in food and soil. It can commonly be found in bathroom sinks and kitchens. It won’t kill you, but it’s side effects aren’t pleasant. Expect a mild illness along with pseudomonas aeruginosa presence.
  • STREPTOCOCCUS associated with strep throat most commonly. It can also result in toxic shock syndrome and flesh-eating bacteria infections known as necrotizing fasciitis, both potentially deadly diagnoses. This bacteria will live and grow in the tiles of your bathroom.
  • ENTEROCOCCUS FAECALIS occupies the gastrointestinal tracts of humans and other mammals once in contact with the body. Keep in mind, this hardy bacteria can survive alkaline cleaning.

Keep an eye on these bacteria hotspots to mitigate any rising growth:

The tiles in kitchens and bathrooms are especially permeable because it accumulates and holds stains from mold and mildew, dust, makeup stains, and dirty water. You may have already noticed this in your bathroom or even in the tiles of your kitchen.
It becomes a breeding ground for bacteria once moisture is added to the mix. Think, hot showers creating steam in your bathroom.

Besides being aesthetically unappealing, the discoloration is likely caused by bacteria which can cause illness.

If this scenario is left unattended, the stains and dirt are confined below the surface and can be difficult to remove.

Avoid this option if you are cleaning limestone or marble. The vinegar can be too harsh for these materials.


Steam mops can effectively kill off 99.9% of bacteria making it an effective way to eliminate bacteria buildup in your home. Because steam mops don’t use any harsh chemicals, this option is an environmentally-friendly alternative.
