How to Clean Upholstery Safely

Sofas and armchairs quietly collect body oils, dust, food and spills, and unlike a carpet you cannot lift them, soak them and dry them out. That makes the method matter even more: the National Carpet Cleaners Association warns that over-wetting can lead to shrinkage, water marks or long drying times.

Read the cleaning code first

Check the care label before you clean, as Which? and the National Carpet Cleaners Association both advise. The codes mean:

• W: clean with water-based products.
• S: clean with solvent-based (dry-cleaning) products. Which? says to check the label has a W or WS code before you get a sofa wet.
• WS: either water-based or solvent-based products can be used.
• X: vacuum only.

If there is no code, test any product on a small, hidden spot first, as Which? advises. If you are unsure how a fabric will react, the National Carpet Cleaners Association says it is safer to stop.

Why the fabric dictates the method

• Natural fabrics need a lighter touch. The IICRC says cotton, linen, silk, wool and rayon can all suffer colour loss, bleeding, texture change, shrinkage or yellowing if not handled with care, and that linen and cotton can brown, or show water rings, when they get wet and dry slowly.
• Synthetics are generally easier to care for: the IICRC says modern synthetic upholstery fabrics can take the stronger measures needed to remove heavy soiling, and Which? says synthetics like microfibre are typically very easy to clean and maintain. The National Carpet Cleaners Association’s course guide adds that microfibre holds moisture from cleaning and dries very slowly.
• Delicate fabrics: the National Carpet Cleaners Association’s course guide lists viscose (rayon) as water sensitive, and Which? calls velvet very delicate and advises checking the manufacturer’s instructions and testing a hidden area first.

How we clean upholstery

We check the fabric and its cleaning code, test an unseen area first, then clean with a fabric-appropriate, low-moisture method. That keeps water to a minimum, which matters because over-wetting can cause shrinkage, water marks and long drying times. It is the same low-moisture approach we use on carpets.

Between professional cleans

• Vacuum upholstery regularly, including under and between cushions.
• Rotate and plump loose cushions so they wear evenly.
• Blot spills straight away, following the cleaning code, and never rub: the National Carpet Cleaners Association says blotting rather than rubbing reduces the risk of spreading a stain or damaging the fabric.
• Avoid over-wetting and harsh supermarket sprays, which can leave rings or sticky residue.
