At what temperature should I wash a cotton fitted sheet?

Wash a cotton fitted sheet at 40°C for daily maintenance, or at 60°C for thorough cleaning during allergies or after illness. The Tuur® Fitted Sheet in organic percale cotton is specially tested for regular washing without shrinking or colour loss. 

• 40°C: standard weekly wash; sufficient for a fresh and hygienic bed
• 60°C: intensive cleaning; kills house dust mites and bacteria effectively
• Avoid 90°C: organic cotton shrinks and loses its softness at too high temperatures
