Which Kitchen and Bathroom Items Harbor the Most Bacteria?
The scrubber you use to wash your dishes can carry more bacteria per square centimeter than the toilet bowl. Here are the five most contaminated items in the kitchen and bathroom, and how often you should clean or replace them.
1. The Kitchen Sponge: Replace It Every One or Two Days
A kitchen sponge stays damp and traps food scraps, making it the ideal environment for bacteria. NSF International found coliform bacteria in 75% of the kitchen sponges it tested.
It's best to replace it every one or two days. After each use, wring it out well and hang it up to dry. If it smells sour, throw it away.
2. The Cutting Board: One for Meat, Another for Vegetables
The grooves in a cutting board trap juices from raw chicken. Over time, they form a biofilm that resists soap.
Use one board for meat and a separate one for vegetables. After each use, scrub it with hot water and a scrubber reserved for kitchen use. Then let it air-dry.
3. Your Phone: Clean It Every Night
If you take your phone into the bathroom, your hands transfer fecal bacteria to the screen. From there, they later end up on your face.
Clean it every night with a cloth dampened with 70% isopropyl alcohol. Always make sure the phone is switched off first.
4. The Sink: Clean It Daily and Dry It Well
A kitchen sink can harbor more fecal bacteria than a toilet. Moisture and food scraps feed pathogens.
Every day, clean the faucet, the sides and the drain with a degreaser. Rinse with hot water, then dry everything to get rid of the moisture.
5. Your Toothbrush: Close the Lid Before You Flush
Flushing without closing the lid releases a spray of fecal bacteria into the air. That spray can travel up to one and a half meters.
Always close the lid before flushing. Store your toothbrush in a cabinet or more than one meter away from the toilet. Also, replace it every three months, as recommended by the American Dental Association.
What About the Toilet? The Real Bathroom Problem Is Limescale and Mold
The toilet isn't the dirtiest spot in the house. Its seat gets cleaned often and it's a dry surface. That's why it carries fewer bacteria than a sponge, a sink or a phone.
What does make a bathroom dirty is limescale and mold. Limescale clogs faucets. Mold releases spores that make asthma worse.
For limescale, dissolve a tablespoon of citric acid in half a liter of warm water. Don't use vinegar on natural stone. For mold, dilute one part bleach in ten parts water, wear gloves and air out the room.
Never mix bleach with ammonia or with acids. Always ventilate the room when using it, and don't use it near children or pets. In case of poisoning, call 91 562 04 20.
