The Real Danger of Cross-Contamination

When you make the mistake of washing kitchen and bathroom towels together without using proper disinfection methods, a few gross things can happen:

• The invisible bacteria living on your kitchen cloths can easily transfer onto the towels you use for your body.
• The thick fibers of your bath towels can trap tiny, unseen food particles left behind by the dishcloths.
• Mold spores from damp bathroom towels can spread across the entire load of laundry.

As a matter of fact, a well-known study from the University of Arizona found that kitchen towels can harbor more bacteria than toilet seats. This is especially true when people use the same kitchen towel for multiple different tasks and forget to wash it frequently.

Best Practices for Washing Towels Together Safely

If you prefer the convenience of washing all your household towels in a single load, you should use these step-by-step methods to minimize any sanitary risks.

1. Sort by the Level of Dirt

Keep heavily soiled kitchen towels away from lightly used bath towels. This prevents heavy grease, food grime, and stains from floating in the water and settling onto your clean bath linens.

2. Pre-Treat Stains Immediately

Apply a splash of liquid detergent or an enzyme-based pre-soak directly to food stains or bodily fluids. This helps break down tough organic matter before the main washing cycle even begins.

3. Always Select Hot Water

Set your washing machine temperature to 140°F (60°C) or higher. High heat alters the structure of proteins and successfully destroys the vast majority of household pathogens.

4. Pick a Detergent with Enzymes

Look for a quality laundry soap that features active enzymes like proteases, lipases, and amylases. These components are excellent at breaking down the stubborn proteins, fats, and carbohydrates found in food stains.

5. Use a Reliable Disinfectant

Add classic chlorine bleach if you are washing a load of pure white towels. For colored towels, use color-safe oxygen bleach or add one cup of plain white vinegar to the wash to add an extra layer of germ-killing power.

6. Give the Laundry Plenty of Room

Never pack the washer tub completely full. Leave enough open space for the towels to tumble and agitate freely, which ensures that the soapy water flows completely through all the thick fabrics.

7. Turn the Dryer to High Heat

Tumble dry your items until they are absolutely bone-dry. You should avoid line-drying towels indoors, as slow drying can encourage mildew. High dryer heat works to eliminate any tiny microbes that managed to survive the wash cycle.

8. Store Items in a Dry Place

Once dry, fold your towels and keep them in a well-ventilated closet or cabinet. Storing them in dark, humid spaces can cause them to absorb moisture from the air, which leads to recontamination.

An excellent pro tip to remember is that if your washing machine does not have a reliable hot water cycle, you can pre-soak your dirty towels in a separate bucket of hot water mixed with detergent before you put them into the machine.
