Wash most everyday sheets at 40 °C / warm (about 100 °F); go up to 60 °C / hot (140 °F) if someone’s sick, you have allergies, or the sheets are very dirty.

Quick Scoop: Ideal Temps

  • Cotton or linen sheets: 40–60 °C (warm to hot), using 40 °C for normal weekly washes and 60 °C when heavily soiled or for extra hygiene.
  • Delicate fabrics (silk, satin, bamboo, some synthetics): 30 °C or cold–lukewarm, gentle cycle, mild detergent, no high heat.
  • Mixed or unknown fabric: 40 °C warm is a safe middle ground, but always check the care label first.
  • Allergy / dust mite concerns: wash at 60 °C occasionally to help kill mites and bacteria.

Simple Rules To Follow

  1. Check the care label first; follow that over any general advice.
  1. For weekly washes, choose 40 °C, normal cycle, mild detergent.
  1. Use 60 °C only when needed (illness, stains, allergies) to avoid wearing fabrics out too fast.
  1. For anything silky, satin-y, bamboo, or very smooth, keep it at 30 °C and a gentle spin.

Polyester / synthetic 30–40 °C to protect fibresUsually not above 40 °C
Silk / satin 30 °C, gentle cycle, mild detergentNever hot; high heat ruins sheen
Bamboo Below 30 °C, gentle spinDo not use warm/hot; can damage fibres

Little “story” example

Imagine Sunday night: you’ve got basic cotton sheets that just did a normal week on the bed. Toss them in at 40 °C with a regular cycle and mild detergent, and they’ll come out clean without shrinking or fading too fast. If the week included a bad cold or a pet accident, you bump that same load to 60 °C once in a while to reset things for hygiene.

TL;DR: For “what temp to wash sheets,” 40 °C warm works for most; check the label, go cooler for delicate fabrics, and reserve 60 °C for grime, allergies, or sickness.
