You've been putting off cleaning that blazer, that silk blouse, or that wool coat for longer than you'd like to admit. And if you've been avoiding the dry cleaner because you're worried your favorite pieces might come back ruined, that hesitation makes perfect sense
Trusting someone else with clothes you spent good money on isn't easy, especially when you're not sure what happens behind the counter. But dry cleaning was built for this. It's how delicate fabrics were always meant to be cleaned.
In this guide, we'll break down exactly how dry cleaning works from start to finish, so you know what to expect before you drop off your first garment.
Dry cleaning isn't completely dry. What it doesn't use is water, and that distinction is what makes it work.
Standard home washing relies on water, detergent, heat, and mechanical agitation. That combination is fine for most everyday fabrics, but it's genuinely damaging to natural materials such as wool, silk, cashmere, and linen, as well as structured garments including tailored suits and blazers.
Water causes natural fibers to swell, contract, and lose tension. Agitation stresses fibers that are already compromised. Heat accelerates the damage. The result is shrinkage, distortion, and garments that don’t fit and look noticeably worse after every wash.
Dry cleaning replaces water with chemical solvents specifically engineered to dissolve oils, grease, and dirt without saturating the fabric. Because the fibers never absorb liquid, they never swell. Because there's no swelling, there's no contraction. The garment comes back the same size, shape, and structure it went in.
Modern dry cleaning has also moved significantly toward greener solvent alternatives. Perchloroethylene, known as PERC, was the industry standard for decades and remains effective, but many quality cleaners now use hydrocarbon or silicone-based solvents that are gentler on fabrics and carry fewer environmental concerns.
At Presso-CC Clean in Portland, we use methods that are better for your clothes and better for our community.
Every garment receives a thorough inspection the moment it arrives. Technicians check for stains, existing damage, weak seams, missing buttons, and any fabric details that need special handling. Each piece is tagged with a unique identifier so it stays tracked through every stage of the process. Nothing gets cleaned without being looked at first, and nothing gets returned that hasn't been checked again at the end.
Stains are treated individually before the main cleaning cycle begins, because different stains require fundamentally different approaches.
Treating them all the same way before cleaning would mean some spots come out and some don't. Targeted pretreatment is what makes the difference between a stain that disappears and one that gets permanently set.
This is also why it matters to tell your cleaner what caused a stain and when it happened. A week-old coffee stain and a fresh coffee stain look similar but behave very differently under treatment.
Garments go into a specialized machine that circulates solvent through the fabric in a controlled environment. The movement is deliberately gentle, far less aggressive than the drum cycle of a home washer, and the temperature throughout the cycle is carefully managed. The solvent is filtered continuously during the cycle to maintain its effectiveness and prevent any residue from one garment transferring to another.
This is the core of the dry cleaning process, and it's where the chemistry does most of the work. Oils, dirt, and residue that water-based washing would struggle to remove without damaging the fabric dissolve cleanly in solvent without causing any structural stress.
After the cleaning cycle, the solvent is extracted, and the garments dry inside the machine using controlled warm air. Because drying occurs at a controlled temperature rather than the aggressive heat of a home dryer, fibers aren't subjected to the thermal stress that causes shrinkage and surface damage in natural fabrics.
Finishing is what makes dry cleaned clothes look the way they do at pickup. Garments are pressed and steamed using professional equipment that applies heat and moisture precisely to relax fibers and restore their natural drape. Structured areas such as shoulders, lapels, and collars are shaped by hand using forms designed to match the intended dimensions of the garment.
Professional pressing equipment works with the three-dimensional structure of the garment rather than against it. This step alone is why many people bring in dress shirts and trousers regularly, with or without visible stains.
Before anything gets returned, a final quality check confirms stains are gone, buttons are intact, and everything looks as it should. Garments are covered for transport and organized for pickup.
One thing worth doing when you get home: take off the plastic covering. It's for transport, not storage. Leaving clothes wrapped in plastic for more than a day or two traps residual moisture and can lead to mildew or yellowing, especially in natural fabrics.
Getting good results from dry cleaning starts before you arrive. None of this takes long, but these steps make a real difference in what you get back.
"Dry Clean Only" means the fabric shouldn't come into contact with water. "Dry Clean Recommended" means it's the safest option, even if it isn't strictly required. If a label says "Do Not Dry Clean," tell your cleaner so they can identify an appropriate alternative method instead of using standard solvents.
You know your own garments better than your cleaner on first look. Point out anything that looks off, especially light or translucent stains from white wine, champagne, or sugary drinks, which can dry completely clear and then oxidize into yellow discoloration inside a sealed garment bag if they go untreated. Tell your cleaner what caused each stain if you know, and roughly when it happened.
It's a natural instinct to dab at a stain or reach for a home stain remover, but many household products set stains deeper into fabric or chemically alter them in ways that make professional removal significantly harder. Leave it for the cleaner.
Receipts and tissues disintegrate during cleaning and can leave residue across other garments. Keys and sharp objects can snag or puncture fabric. Check jacket pockets, trouser pockets, and any interior breast pockets before leaving home.
If a jacket and trousers are a set, take them in together and keep them together at drop-off. Cleaning them in separate visits can create slight color or finish variations that become noticeable when the pieces are worn together.
Care labels use standardized symbols that are consistent across most clothing brands. Those most relevant to dry cleaning are:
A circle on its own means the garment can be dry cleaned. A circle with a letter inside tells the cleaner which solvent type is safe: P means any solvent, F means petroleum-based solvent only. A circle with an X through it means do not dry clean, and your cleaner should know this before touching the garment with any solvent.
An underline beneath the circle means use a gentle cycle. Two underlines mean use an extra-gentle cycle. These are instructions for the machine settings, not for you, but knowing they're there helps you understand why cleaners sometimes treat similar-looking garments differently.
If a label is worn away or missing, tell your cleaner. They can often identify appropriate cleaning methods based on the fabric itself, but a missing label is always worth flagging up front.
That blazer at the back of your closet. The silk blouse you've been avoiding. The wool coat you wore twice last winter and then panicked about cleaning. They're not damaged. They've just been waiting for you to know what to do with them.

Most fabrics handle dry cleaning well, and many delicate fabrics are genuinely safer in dry cleaning than in any home washing method. A small number of specialty items, including some heavily embellished garments and certain waterproof treatments, require specific approaches. A professional dry cleaner inspects every garment before cleaning and flags any concerns before proceeding.
Standard turnaround at most professional cleaners is two to three business days. Rush service is often available for an additional fee if you need something back faster. Ask at drop-off if timing is a concern rather than assuming a standard turnaround fits your schedule.
For regularly worn suits and blazers, two to three professional cleanings per year is a reasonable baseline. Between cleanings, spot-treating minor marks and using a clothes brush to remove surface dust and lint extend the life of the garment and reduce how often full cleaning is necessary.
Properly executed dry cleaning should not cause shrinkage. Because the process uses no water, the primary cause of fiber contraction in natural fabrics is never present. Garments that come back smaller than they go in were either cleaned incorrectly or had pre-existing issues the cleaning process revealed.
Dry cleaning uses chemical solvents and is designed for delicate, structured, or high-care garments. Wash and fold uses water, detergent, and heat and is appropriate for everyday fabrics such as cotton and polyester, as well as most casual clothing. Your care labels tell you which method each garment needs.
