White Sheer Curtains

White sheer curtains in 60 gsm solution-dyed polyester voile at a 5% openness factor — no optical brightener — woven 118 in. wide, French-seamed, with a 3 in. cord-weighted hem. Our white sheer curtains are 40 °C washable weekly without yellowing and available in two whites: Alabaster (cool optic) and Bone (warm ivory).

Why white sheer curtains yellow and how ours don’t

White sheers get replaced rather than cleaned, and the reason is a bit of building physics nobody explains at the point of sale. A sheer hangs directly against the glass, which is the coldest surface in the room and therefore the place where airborne moisture condenses. Dust in the air lands on damp cloth and stays. Add a radiator underneath pushing a warm dirty updraught through an open weave and you have built an air filter.

What kills most white sheer curtains: optical brighteners

So the only white sheer worth buying is one specified to be washed repeatedly, and this is the part where most fail. Cheap white sheers are brightened rather than bleached — dosed with a fluorescent whitening agent that absorbs UV and re-emits it as blue, which fools the eye into reading the cloth as brighter than white. It works beautifully for about eighteen months. Then the agent degrades, unevenly, and the panel goes yellow-grey in patches that no amount of washing lifts.

Solution-dyed white, no optical brightener

This is woven from solution-dyed white polyester with no optical brightener in it at all. The white is the actual colour of the fibre rather than a coating on it, so what you see on day one is what you see in year eight. It also means you can wash it at 40 °C weekly without consequence, and can use an oxygen bleach on a mark without stripping the finish.

Two whites, and where each belongs

Two whites, because they behave differently in a room. Alabaster is a true cool optic white, correct against white paint and cool daylight. Bone is a warm ivory that holds its own against timber, brass and warm-white bulbs, where a cool white reads faintly blue and clinical after dark.

Frequently asked questions

Do white sheer curtains yellow with age?

Cheap brightened ones do — the optical brightener degrades unevenly. Ours are solution-dyed white with no brightener; what you see day one is what you see year eight.

Alabaster or Bone white sheer curtains?

Alabaster against cool paint and daylight. Bone against timber, brass and warm-white bulbs.

Can I wash white sheer curtains weekly?

Ours yes — 40 °C weekly. That’s exactly what the cloth is specified for.

What detergent for white sheer curtains?

Any normal detergent — but never a whitening one. Whitening detergents add back the exact chemistry this cloth avoids.
