A washing machine should leave clothes looking and smelling clean, but sometimes freshly washed laundry still has an unpleasant smell. Often, the issue isn't that you need a different detergent or a new machine—it's that residue wasn't fully removed during the wash cycle. Body oils, bacteria, detergent buildup, and mineral deposits can all contribute to smells that remain trapped in fabric. If your laundry isn't coming out as fresh as you'd expect, one of these common laundry mistakes may be the reason.
You're using too much detergent
It may seem like extra detergent would leave clothes cleaner, but using too much can actually have the opposite effect. Excess detergent doesn't always rinse away completely, leaving behind residue that traps body oils, bacteria, and other odor-causing residue in fabrics.
Always measure detergent according to the manufacturer's instructions, adjusting for load size, soil level, and water hardness. If you have a high-efficiency washer, be sure you're using HE detergent.
You're overloading the washing machine
Packing too many clothes into the drum prevents water and detergent from circulating freely. Without enough room to move, clothes can't rub against one another during the wash cycle, making it harder to remove sweat, body oils, and odor-causing residue.
The drum should be full, but not packed. You should be able to fit your hand inside with a little room to move it around.
You're using the wrong water temperature
Cold water is effective for most everyday loads when paired with a quality detergent, and it's often the best choice for delicate fabrics like silk, rayon, wool, and spandex.
That said, warm or hot water can do a better job breaking down body oils, dirt, and heavy soil that contribute to lingering odors. For towels, bedding, and sweaty workout clothes, washing in the hottest water that's safe for the fabric may help eliminate stubborn smells. Always check the care label before increasing the water temperature.
You’re not rinsing away trapped residue
Even when you're using the right amount of detergent, some laundry loads can benefit from an extra rinse to help remove trapped detergent, body oils, and other residue from fabric fibers—especially items like towels, bedding, and workout clothes.
You can add an extra rinse cycle to your wash or use a laundry rinse product, like Downy Rinse & Refresh, which is designed to help remove odors and residue from fabrics rather than coat fibers the way traditional fabric softeners can.
You're leaving wet clothes in the washer
Even clean clothes can develop unpleasant odors if they sit damp in the washing machine for too long after the cycle ends. Lingering moisture allows odor-causing bacteria to multiply, leaving laundry smelling stale by the time you move it to the dryer.
Transfer clothes to the dryer or hang them to dry as soon as the wash cycle finishes. If you accidentally leave a load sitting for several hours, rewash it before drying to help remove the odor.
Your washing machine needs cleaning
Even though your washing machine cleans your clothes, it still needs regular maintenance. Over time, detergent residue, body oils, and mineral deposits from hard water can build up inside the machine, making it harder for your washer to clean effectively and contributing to unpleasant smells.
Run your washer's self-clean cycle (or a hot cycle with a washing machine cleaner) about once a month. If you have particularly hard water, you may need to clean your machine more often since mineral deposits can accumulate more quickly. It's also important to clean the detergent dispenser drawer, wipe down the door gasket on front-load washers, and leave the washer door open after each load so the drum can dry completely.
