Items carrying the highest levels of germs should be sanitized regularly. This includes, for example, bedding used by an ill family member. However, not every laundry load requires this level of treatment. Standard washing with detergent removes a portion of bacteria and soils, but sanitization—achieved through elevated temperatures or chemical agents—is intended to eliminate 99.9 percent of germs in conjunction with detergent use.
The sanitize cycle available on many washing machines utilizes extremely hot water to achieve this level of bacterial reduction. While effective when needed, frequent use is not recommended, as the high temperatures can be harsh on fabrics and may contribute to fading over time.
This cycle is particularly beneficial when household members are ill. Sanitizing sheets, towels, and clothing used by a sick individual can help reduce the spread of germs and protect others in the home from infection.
Employ the Sanitize Cycle
When a washing machine includes a "sanitary" or "sanitize" setting, and the fabrics being laundered are rated for high-temperature washing, this feature offers a convenient method for sanitizing laundry. Cotton items, for example, typically tolerate the elevated heat used during such cycles. However, garments containing elastic, spandex, wool, or other heat-sensitive materials require caution. Checking the care label on each item before proceeding is advisable.
Use the Dryer
For items unsuitable for hot water washing yet capable of withstanding high heat, a dryer with a "steam sanitary" cycle may provide a suitable solution. This approach can work well for articles such as plush toys or certain pillows, though down-filled products are generally not recommended for this treatment.
Add a Laundry Sanitizer
If the washing machine lacks a sanitize cycle, or if the garments are not heat-tolerant, using a commercial laundry sanitizer provides an effective alternative. Although bleach has traditionally been the standard for sanitizing bleach-safe whites, specially formulated laundry sanitizers are available to treat items that cannot be processed with chlorine bleach.
