We have noticed that when the weather gets hotter outside, toilets start having the black mold under the toilet rim. Toilets that don’t get used often and the lid is kept down is a breeding ground.
What causes this to happen?
Mold & Mildew
High humidity in a bathroom causes mold and mildew build up. Ways to prevent this from happening is by turning on the ventilation fan, if you don’t have one than cracking a window.
Serratia marcescens is a type of bacteria that grows in dark, damp places. This type of bacteria can also be disguised as a pinkish color ring in the toilet, in a sink or tub. Bacteria is harmful to humans and can cause urinary tract infections, wound infections and pneumonia. Bacteria also have antibiotic resistant properties that prevent wounds from healing quickly.
How to Clean
First disinfect the toilet brush with a 1 to 1 solution of hydrogen peroxide.
Pour a cup of vinegar into the toilet bowl and swish it around.
If the black mold has been there awhile. Deep cleaning will be necessary. Make a paste with Borax and vinegar or lemon juice apply it under the rim and let it work for several hours.
Regular cleaning and disinfecting the toilet will help prevent illness and the build up.
