Household fabrics often accumulate allergens, pollutants, and irritants more quickly than many people realize, highlighting the need for more frequent laundering, experts say. The issue is particularly critical for individuals with allergies, asthma, eczema, or other skin conditions, as well as for pet owners.

Melanie Carver, chief mission officer of the Asthma and Allergy Foundation of America, emphasized that textiles can harbor pollen, dust mites, animal dander, mold, and irritating chemicals. “Staying on top of laundering commonly overlooked fabrics can reduce exposure to these triggers,” she said.

Scott Grillo, a home-cleaning and laundry specialist at FurZapper, noted that fabrics throughout the home collect hair, dust, allergens, and odors, especially in homes with pets. Both experts recommend adjusting laundry routines to address these hidden accumulations.

Curtains and drapes often trap dust and allergens but are frequently neglected during regular cleaning. Carver recommended vacuuming curtains weekly using upholstery attachments and washing them every three months. In moisture-prone areas such as bathrooms and kitchens, more frequent washing may be necessary to prevent mold and odor buildup.

Throw blankets, commonly found on couches, chairs, and beds, can accumulate pet hair, dander, body oils, and dust quickly. Grillo suggested washing these items every one to two weeks based on usage. Upholstered furniture should also be vacuumed weekly to manage dust mites, pollen, and pet dander. If slipcovers are present, they should be laundered regularly, with deep cleaning every three to six months.

Kitchen linens require close attention, especially towels and dishcloths. Grillo stressed the importance of washing kitchen towels in hot water every one to two days and always after contact with raw meat or fish; fabric softeners should be avoided as they reduce absorbency. Oven mitts and potholders are often overlooked but should be washed every one to two weeks to remove grease and cooking residues.

Bath and hand towels should be washed frequently to minimize mold, mildew, and dust mite accumulation. Carver recommended washing bath towels after every use for those with eczema and every few uses in other cases. Bath mats and rugs, which retain moisture, should be washed monthly or more often in humid environments to prevent mold growth.

Shower curtains and liners, particularly plastic ones, are susceptible to mold and mildew. Carver advised leaving curtains fully extended after showering and using ventilation to minimize moisture. Plastic and fabric curtains can typically be machine washed, though harsh cleaners like bleach should be avoided due to potential respiratory irritation.

Pet beds, described by Grillo as a major fabric offender, trap fur, odors, dirt, and allergens. He advised washing removable covers weekly or at least biweekly. Bed pillows should be laundered every three to six months and after illness, with drying techniques that promote even fluffing.

Other frequently neglected items include stuffed toys, which harbor dust mites and should be washed monthly or vacuumed if washing is not possible, and throw pillows, where covers might benefit from washing every two to four weeks.

Finally, mattress covers—particularly for those with allergies or pets—require regular washing, ideally weekly or monthly, with hot water and high-heat drying to reduce dust mites. For covers that are difficult to remove, vacuuming is recommended.

Grillo also highlighted fabric placemats and table runners as spaces that collect more debris and allergens than commonly recognized and suggested laundering them every one to two weeks.

Overall, maintaining a rigorous laundering schedule for these often-overlooked household fabrics can help reduce allergens, odors, and the presence of irritants, thereby improving indoor environmental quality.
