One of the main reasons for washer odor is the accumulation of soap scum, which is a sticky film that forms when soap isn't fully rinsed away. This scum can harbor mildew, bacteria, and mold, all of which contribute to that sour smell.

Using the wrong type or amount of detergent can also lead to washer odor. If you're using high-efficiency detergent in a front-load washer, it's essential to use the right amount, as too much can leave behind a residue that traps moisture and bacteria.

Using the right amount of detergent is crucial. Too much soap can leave behind a residue that traps moisture and bacteria, causing odors to form. Stick to the recommended dose to prevent buildup.

Leaving the washer door open after every load allows the drum to dry out, preventing moisture from sitting inside and creating a breeding ground for mold. This simple habit can make a big difference in keeping your washer odor-free.

Wiping the gasket and drum dry after each use can also help prevent mildew from forming in hard-to-reach areas. It only takes a few seconds, but it's an important step in maintaining a clean washer.

To clean and sanitize effectively, it's essential to understand the difference between cleaning and sanitizing. Cleaning removes dirt and germs from surfaces, while sanitizing reduces the number of germs to a safe level.

Start by gathering all-purpose cleaners and disinfectants, which are effective against a wide range of germs. According to the CDC, bleach is a strong disinfectant that can kill 99.9% of germs, including E. coli and Salmonella.

Begin by dusting and vacuuming surfaces to remove loose dirt and debris. This will make it easier to clean and sanitize the area. Dusting and vacuuming can help prevent the spread of germs.

A unique perspective: Sanitize Clothes Washer

For surfaces that require sanitizing, use a disinfectant that is EPA-registered and follows the manufacturer's instructions. The EPA recommends using a disinfectant that is effective against a broad spectrum of germs, including norovirus and rotavirus.

Remember to always wash your hands after cleaning and sanitizing, especially after touching bleach or other strong disinfectants. This will help prevent the spread of germs to yourself and others.

Using the right kind of detergent is crucial, especially if you have a high-efficiency (HE) washer. You'll need to use specially formulated HE detergents to avoid residue buildup and odors.

Always follow the manufacturer's instructions and use any measuring cups provided to ensure you're using the right amount of detergent and fabric softener.

This buildup can lead to a sour smell in the washing machine, and in extreme cases, clog the pipes so the machine doesn't work optimally. Fabric softener can be bad for your skin and the environment too.

It's recommended to run one machine clean after using fabric softener that's accumulated, and then get rid of regular fabric softener completely. This will help keep your machine in good condition and smelling fresh.
