If you’ve ever checked a garment label and seen “Dry Clean Only,” you’ve probably asked yourself: what is dry cleaning, exactly, and why can’t I just throw it in the washing machine? What is dry cleaning? In simple terms, dry cleaning is a professional garment-cleaning process that removes dirt, oils and stains using a liquid solvent instead of water. Despite the name, dry cleaning isn’t actually “dry”; your clothes are still submerged in liquid, but that liquid is a gentle chemical solvent rather than water, which is why delicate fabrics come out clean without shrinking, bleeding colour, or losing their shape.
At Elegance Dry Cleaners, we’re asked this question every day by customers across London, so we’ve put together this complete guide covering exactly what dry cleaning is, how dry cleaning works from drop-off to collection, when you should choose it over regular laundry, and how to look after your dry-cleaned garments at home. Whether you’re new to professional garment care or just want a refresher, this guide answers every question you might have.
What Is Dry Cleaning?
So, what is dry cleaning at its core? Dry cleaning is a method of cleaning clothes and textiles using a chemical solvent most commonly perchloroethylene (perc), hydrocarbons, or newer silicone-based solvents such as decamethylcyclopentasiloxane instead of water and detergent. The term “dry” simply refers to the absence of water, not the absence of liquid.
Here’s why that distinction matters:
- Water can damage certain fabrics. Fibres like silk, wool, rayon, and viscose can shrink, warp, or lose their dye when exposed to water and the agitation of a washing machine.
- Solvents clean without swelling the fibres. Because dry cleaning solvents don’t cause natural fibres to swell the way water does, garments hold their shape, drape, and structure far better.
- It lifts oil-based stains effectively. Many stains — grease, make-up, ink — are oil-based and respond better to solvent cleaning than to water-based washing.
In short, dry cleaning exists to answer a very practical problem: how do you clean delicate, structured, or heavily embellished clothing without ruining it? That’s the essence of what dry cleaning is, and it’s why the process has remained the industry standard for over a century.

How Does Dry Cleaning Work? A Step-by-Step Breakdown
Understanding what dry cleaning is naturally leads to the next question: how does dry cleaning work in practice? At Elegance Dry Cleaners, every garment goes through a precise, multi-stage process to guarantee consistent, safe results. Here’s exactly how dry cleaning works, from the moment your item arrives to the moment it’s ready for collection.
1. Inspection and Garment Tagging
Before any cleaning begins, every item is inspected for:
- Fabric type and fibre content
- Colourfastness (whether dyes are likely to run)
- Existing stains, pollen, or general wear
- Manufacturer care instructions on the label
Each garment is then tagged with a unique barcode so it can be tracked accurately through every stage of the process — this is a core part of how dry cleaning works at a professional level, ensuring nothing is lost or mixed up.
2. Pre-Spotting and Stain Treatment
Stains are treated individually before the main cleaning cycle, because the solvent bath alone won’t remove every mark. For example:
- Grease and oil stains are treated with a targeted hydrocarbon-based solvent.
- Protein-based stains (blood, sweat, food) respond best to enzymatic pre-treatment solutions.
- Dye-based stains, such as wine or ink, often require more complex, case-by-case chemistry.
This targeted approach is one of the biggest reasons professional dry cleaning consistently outperforms home remedies.
3. The Cleaning Cycle
Once pre-treated, garments go into a specialised machine that’s similar in appearance to a washing machine but is designed to use solvent instead of water. Here’s how dry cleaning works during this stage:
- Garments are loaded into a sealed drum and gently agitated in the solvent.
- Cycle times typically run between 8 and 30 minutes, depending on fabric type and soil level.
- Temperatures stay low — usually under 30°C — to protect delicate fibres.
- The solvent is filtered and recycled after each use, which reduces waste and keeps costs manageable.
4. Post-Clean Inspection
After the cleaning cycle, each garment is checked again. If any stains remain, a trained technician applies further spot-treatment by hand before moving the item forward. This quality-control step is essential — it’s what separates a reliable dry cleaner from a corner-cutting one.
5. Finishing and Pressing
The final stage is where garments regain their crisp, “just bought” appearance:
- Steaming to remove wrinkles and restore natural drape
- Pressing on specialist finishing equipment shaped for suits, shirts, and dresses
- Minor repairs carried out on request (buttons, loose hems, small tears)
- Folding or hanging based on customer preference
6. Final Quality Check and Packaging
Before your items are returned to you, they go through one last quality check. At Elegance Dry Cleaners, garments are protected in breathable, eco-friendly covers rather than standard plastic, so they arrive back in perfect condition without unnecessary waste.
What Chemicals Are Used in Dry Cleaning?
A common follow-up to “what is dry cleaning” is what’s actually in the solvent. The most widely used dry cleaning solvents include:
- Perchloroethylene (perc) – the traditional industry solvent, highly effective but increasingly being phased out in favour of greener alternatives.
- Hydrocarbon solvents – a gentler, petroleum-based option often used for delicate or heavily embellished items.
- Silicone-based solvents (GreenEarth/decamethylcyclopentasiloxane) – a newer, more environmentally friendly option that’s gentle on fabrics and low in toxicity.
Reputable dry cleaners are increasingly shifting toward these eco-conscious solvents, both for environmental reasons and because they tend to be gentler on fine fabrics like silk and cashmere. When you’re choosing a provider, it’s worth asking directly which solvent they use — it’s a simple question that tells you a lot about the quality and environmental standards behind their service.
If you’re still wondering what is dry cleaning best suited for, the short answer is: any fabric that can’t safely handle water, agitation, or high heat.
Dry Cleaning vs Regular Washing: What’s the Difference?
| Factor | Dry Cleaning | Regular Washing |
|---|---|---|
| Cleaning agent | Chemical solvent | Water and detergent |
| Fabric safety | Safe for silk, wool, rayon, viscose | Can shrink or damage delicate fibres |
| Stain removal | Excellent for oil-based stains | Better for water-based stains |
| Shrinkage risk | Very low | Higher for natural fibres |
| Colour retention | Excellent | Can cause fading/bleeding |
| Best for | Suits, gowns, coats, curtains | Cotton, everyday casualwear |
Understanding this comparison makes it clear why dry cleaning isn’t just a luxury — for certain fabrics, it’s the only safe cleaning method available.
When Should You Choose Dry Cleaning?
Not every item needs dry cleaning, but for the following, it’s strongly recommended:
- Suits and blazers – to preserve structure and prevent shrinkage
- Evening gowns – especially those made from silk, chiffon, or sequinned fabric
- Wedding dresses – professional cleaning helps preserve them for years
- Wool coats and jackets – water exposure can cause shrinkage and felting
- Curtains and drapes – too large for a domestic washer and prone to collecting dust and pollen
- Anything labelled “Dry Clean Only” or “Dry Clean Recommended”
Even garments marked “dry clean recommended” rather than mandatory tend to last significantly longer, and keep their shape and colour better, when professionally cleaned rather than machine-washed. As a rule of thumb, if you’re unsure whether an item needs it, checking what is dry cleaning suited for on the care label is always the safest first step before you reach for the washing machine.
Benefits of Dry Cleaning
- Preserves garment shape and structure far better than home washing
- Protects delicate embellishments like sequins, beading, and lace
- Removes tough, oil-based stains that water alone can’t shift
- Extends the lifespan of expensive or sentimental clothing
- Saves time compared with hand-washing delicate items at home
- Includes professional pressing and finishing, giving a polished result you can’t easily replicate
Common Mistakes People Make With Dry Cleaning
- Ignoring the care label. Ignoring a “Dry Clean Only” tag and machine-washing anyway is one of the most common — and costly — mistakes.
- Delaying stain treatment. The longer a stain sits, the harder it becomes to remove, even with professional solvents.
- Storing garments in plastic long-term. Plastic covers trap moisture and can cause discolouration over time; breathable garment bags are far better for storage.
- Assuming all dry cleaners use the same process. Quality, solvents, and finishing standards vary significantly between providers.
- Over-cleaning. Dry cleaning too frequently can gradually wear down certain fabrics; only clean when genuinely needed.
How Much Does Dry Cleaning Cost in the UK?
Costs vary depending on garment type, fabric, and location, but as a general guide:
- Shirts and blouses: typically £4–£8
- Trousers/skirts: typically £6–£10
- Suits (two-piece): typically £12–£20
- Coats and jackets: typically £12–£25
- Wedding dresses and gowns: typically £50–£150+, depending on fabric and detailing
Prices in central London are often at the higher end of these ranges due to overheads, but the investment is usually far lower than the cost of replacing a damaged garment.
Expert Care Tips for Your Dry-Cleaned Garments
- Remove the plastic cover as soon as you get home — it traps moisture and can cause odours.
- Air garments out for an hour or two before storing them in a wardrobe.
- Avoid direct sunlight and damp storage, both of which can fade colours or encourage mould.
- Use padded or wooden hangers for structured items like suits and coats to help them keep their shape.
- Brush between cleanings with a garment brush or lint roller to remove surface dust and extend the time between professional cleans.

Frequently Asked Questions About Dry Cleaning
What is dry cleaning in simple terms?
Dry cleaning is a way of cleaning clothes using a liquid chemical solvent instead of water, which allows delicate fabrics to be cleaned safely without shrinking, fading, or losing shape.
How dry cleaning works without water, in short
Dry cleaning works by submerging garments in a chemical solvent, rather than water, inside a specialised machine. The solvent lifts dirt and oils from the fabric without causing the fibres to swell or shrink, and it’s filtered and reused throughout the cleaning cycle.
Is dry cleaning better than washing at home?
For delicate fabrics like silk, wool, and rayon, yes — dry cleaning is significantly safer and more effective than home washing, particularly for oil-based stains and structured garments like suits.
How often should I dry clean my clothes?
It depends on usage, but as a general rule: suits every 3–5 wears, coats once or twice a season, and evening wear after each use or before long-term storage.
Can all fabrics be dry cleaned?
Most fabrics can be dry cleaned, but always check the care label first. Some fabrics with certain glues, coatings, or trims may require a specific solvent or a specialist cleaner.
Is dry cleaning bad for the environment?
Traditional perc-based dry cleaning has faced environmental scrutiny, which is why many professional cleaners, including Elegance Dry Cleaners, are moving toward greener hydrocarbon and silicone-based solvents that are gentler on both fabrics and the environment.
