How to wash a sheet: temperature for cotton, satin and microfibre
It is not the mattress that ruins a sheet, but one programme for every fabric. Cotton can take heat, satin cannot, microfibre dries fast but goes stiff and loses softness if you overheat it. Choose the temperature from the label and from what the sheet is made of.
Before the first night
Wash a new sheet before you put it on the bed. The first wash removes the finish and lets the fabric shrink in the machine, not on the mattress. For most models, 40 °C is enough.
Cotton — warmer is fine
Pure cotton usually copes with 40–60 °C if the label says so. 60 °C helps hygiene and dust mites. Daily 90 °C is not needed: colour fades, seams age, and the elastic on a fitted sheet loses stretch faster than the stains do.
Wash jersey (knit cotton) the same way, but do not pack the drum. The stretch fabric pulls out of shape if it spins crushed against heavy clothes.
White cotton can go with other whites. Coloured — separately for the first washes, until the dye settles. Do not pour bleach on coloured sheets.
Satin — stay at 40 °C
Premium satin and microfibre satin want a gentler cycle. 40 °C is usually enough. Hotter water, bleach and harsh powder take the sheen and leave the surface rougher.
Do not wash satin with jeans and zips. Friction leaves pills you will not iron out. Softener does not make satin “smoother in a nice way” — it increases slip and weighs the fibres down.
Smooth it when you take it out. You often will not need an iron.
Microfibre — warm, not boiling
Microfibre dries quickly and is often labelled hypoallergenic, so people wash it too hot “to get it clean”. 40 °C is enough for most models. High heat can stiffen the fibre and take away the softness you bought the sheet for.
Keep microfibre, like satin, away from rough garments. Dry it moderately. Too much heat is not hygiene — it is a shorter life.
Fitted sheets
Elastic fears heat more than the fabric does. Even if the cotton can take 60 °C, dry it in the air or on a low dryer setting. Pull the corners so the band returns to shape.
What not to add to every wash
Softener weakens elastic and only makes satin more slippery. An overloaded drum rubs every fabric. A damp sheet left rolled in the basket leaves creases you will not smooth out of satin in a minute.
If the label says something other than this text, the label wins. The maker knows the weave.
Cotton, satin and microfibre sheets, fitted and flat, are at Savas Home. Go to Savas Home and check the care line on the model before the first wash.
In short: cotton 40–60 °C, satin and microfibre around 40 °C, no hot dryer for the elastic, no softener.
