What Professional Upholstery Cleaning Involves
Professional furniture cleaning is more than running a machine over the fabric. Here's what actually happens before, during and after a visit — and why the fabric itself decides the method.

Step One: Identify the Fabric
Before anything is applied, a professional identifies what the furniture is made of. Synthetic microfibre, cotton blends, linen, wool, velvet and leather all behave differently, and the same product that freshens one fabric can watermark or damage another. Construction matters too — cushion fill, backing fabric and how the piece is assembled all affect how much moisture is safe.
Step Two: Check the Cleaning Code
Most furniture carries a tag with a cleaning code — W, S, WS/SW or X — which indicates whether water-based or solvent-based cleaning is appropriate, or whether the piece shouldn't be wet-cleaned at all. The code is a starting point rather than the whole answer, since dyes, finishes and age also play a part. Our guide to W, S, WS and X cleaning codes explains where to find the tag and what each letter means.
Step Three: Test, Then Choose a Method
A small hidden area is tested for colourfastness and reaction before the main clean. Based on the fabric, code and test result, the technician chooses an approach:
Hot Water Extraction
A cleaning solution is applied and then extracted along with loosened soil. Effective on many durable, water-safe fabrics, with moisture kept under control.
Low-Moisture or Solvent Cleaning
Used for fabrics that don't tolerate water well. The goal is to clean the surface while keeping the piece as dry as practical.
Delicate or Hand Cleaning
For sensitive fabrics, trims and pieces where machine work would be too aggressive.
Step Four: Grooming and Drying
After cleaning, the pile may be groomed so it dries evenly, and cushions are positioned for airflow. Drying time depends on fabric, how much moisture was used, and the room's temperature and ventilation — our guide to couch drying times covers what to expect.
What Results to Expect
Most furniture comes up noticeably fresher and brighter, and many stains and odours improve. Honest limits apply: set-in staining, dye damage, wear and some odours may be reduced rather than removed, and no reputable cleaner will promise otherwise before seeing the piece.

Frequently Asked Questions
Do I need to do anything before the appointment?
Clear small items off the furniture and nearby tables, and point out any stains or concerns. The technician handles the rest.
Is professional cleaning safe for delicate fabrics?
Yes, when the fabric is identified first and the method is matched to it. Testing a hidden area is a standard part of the process.
How long does furniture take to dry?
It varies with fabric, moisture used and room conditions — often a few hours. Ventilation and airflow speed it up.
Can every stain be removed from upholstery?
No. Many improve a great deal, but some staining and wear is permanent. A good technician will tell you honestly what to expect.
