Expert Weighs In: Is Frequent Washing or Bulk Laundry Better?
Frequent small laundry loads are more cost-effective than bulk washing, according to a Japanese laundry expert, as infrequent washing allows stains to set deeper and overloaded machines clean less efficiently.
Settling a household debate: which is more cost-effective for water bills—doing laundry all at once or washing frequently? A Japanese laundry expert reveals an answer that surprises many.
With living costs on the rise, many families are trying to cut household expenses. One common strategy is to "do one big load of laundry on the weekend" to save on water and electricity bills. However, Japanese laundry expert Rie Hirajima has revealed that bulk washing may not be the money-saver many assume it to be.
Hirajima explains that the most recommended approach is "regular, frequent washing with smaller loads," because bulk washing can actually become "a false economy that costs more in the end."
Stains set deeper, harder to wash out, leaving yellowing and odors
The longer clothes sit before washing, the more sweat stains, dirt, and odors seep deep into fabric fibers, making them harder to remove. This can result in yellowed clothes, musty smells, or the need for multiple wash cycles—ultimately using more water, detergent, and electricity than before.
Overloading the machine reduces cleaning efficiency
Another problem with bulk washing is that people often stuff machines to capacity, preventing clothes from moving freely. This makes it harder for dirt to release from fabrics.
Recommendations: - Top-load washers: fill to 70-80% capacity - Drum washers: fill to only 50% to allow room for rotation and agitation, which are crucial to effective cleaning
Hoping to save water costs, but ending up spending more
While many choose bulk washing to reduce water bills, experts point out that if clothes don't get clean and need rewashing, or develop yellow stains requiring replacement, the total cost exceeds whatever water savings were attempted.
If bulk washing is unavoidable, here's what to do:
1. Address heavily soiled clothes first Sweat-soaked or stained clothes should be washed the same day to prevent odors and stubborn stains from setting.
2. Don't leave clothes in the washer Leaving wet clothes in the machine creates dampness and mold growth. Use a well-ventilated laundry basket instead.
3. Air-dry damp clothes first Especially towels—if left wet, bacteria multiply and odors develop easily. If you can't wash immediately, hang them to dry first.
Those drying clothes indoors should "wash less but more often"
For those air-drying indoors or in condos, washing smaller loads helps clothes dry faster and prevents musty smells from incomplete drying. Washing large batches at once and hanging them all together creates moisture buildup and slower drying, easily leading to "damp odors."
In an era of rising water, electricity, and product costs, proper clothing care not only reduces expenses but also extends the lifespan of your favorite clothes.
