White Curtains: Yellowing and Suitable Care
Greying may reflect accumulated dirt, while yellowing can also relate to the fabric and its exposure. Bleaching does not solve every colour change; begin with the care label.
Last updated: 10 October 2026Understand the colour change
Dust, smoke, grease and detergent residue differ from a change in the fibre or coating itself. Record when the yellowing appeared and which treatments have already been used. Permanent material changes cannot be assumed to return to their original white.
Follow the fabric label
Wash only curtains labelled as washable, using the permitted programme, temperature, load and detergent. Sheers, linen blends, lined curtains and blackout surfaces need different care. A supplier’s recommendation for one washable fabric is not a universal curtain-cleaning recipe.
Avoid unverified whitening recipes
Sugar, dishwasher tablets, vinegar and bicarbonate are not validated whitening treatments for every curtain fabric. Use bleach only where the product instructions allow it. Do not mix cleaning agents or increase the dose in an attempt to overcome a persistent colour change.
Rinse, dry and reassess
Follow the specified detergent dose, rinsing, drying and ironing instructions. There is no single spin speed or heat setting suitable for all curtains. If yellowing remains, seek an assessment using the care label and treatment history rather than repeating chemical treatments.
