What Is Dry Cleaning? A Complete Guide
· Dry Cleaning
Dry cleaning is one of those services that most people use without fully understanding how it works. You drop off a suit or a delicate dress, and a few days later it comes back clean, pressed, and ready to wear. But what actually happens behind the counter? And why do certain fabrics need dry cleaning in the first place?
As graduates of the International Fabricare Institute in the United States, the Royal Clean team has spent nearly four decades mastering every aspect of professional garment care. This guide explains the science, the process, and the reasons behind dry cleaning — helping you make informed decisions about how to care for your most valued clothing.
The Science Behind Dry Cleaning
Despite its name, dry cleaning is not dry at all. The term simply means that water is not used as the primary cleaning agent. Instead, garments are immersed in a liquid solvent — a chemical compound that dissolves oils, greases, and many types of stains without the swelling, distortion, and colour bleeding that water causes in sensitive fabrics.
Water is an excellent solvent for many things, but it is problematic for delicate textiles. When natural fibres like silk and wool absorb water, they swell and change shape. The mechanical agitation of a washing machine compounds this effect, causing shrinkage, stretching, and structural damage. Dry cleaning solvents penetrate the fabric and dissolve soil without triggering these destructive reactions.
The most widely used solvent historically has been perchloroethylene (commonly called "perc"), though the industry has increasingly shifted toward safer, more environmentally responsible alternatives. At Royal Clean, we use only eco-friendly, non-toxic solvents that deliver excellent cleaning performance while protecting our staff, our customers, and the environment.
A Brief History of Dry Cleaning
The concept of solvent-based cleaning dates to the early nineteenth century. In 1821, Thomas Jennings, a tailor working in New York, developed and patented a process he called "dry scouring." Jennings holds the distinction of being the first African American to receive a patent in the United States — a remarkable achievement that laid the foundation for an entire industry.
Over the following two centuries, the process evolved from crude kerosene-based methods to the sophisticated, computer-controlled systems used today. Modern dry cleaning machines are closed-loop systems that recover and recycle solvents, minimizing waste and environmental impact.
Royal Clean's Six-Step Professional Process
At Royal Clean, every garment that enters our facility passes through a meticulous six-step workflow:
1. Inspection. We examine each item for stains, damage, loose buttons, and any features that require special handling. Pockets are emptied, and garments are tagged with unique identifiers to prevent mixing.
2. Pre-Treatment. Problem areas — stains, perspiration marks, ground-in soil — receive targeted treatment before the main cleaning cycle. Different stain types require different chemistry: enzyme solutions for organic matter, solvent-based agents for oil and grease, and oxidizing treatments for tannin stains like coffee or wine.
3. Cleaning. Garments enter the dry cleaning machine, where they rotate gently in a bath of filtered solvent. The solvent passes continuously through a filtration system that removes impurities, then returns to the cleaning chamber. A final rinse with freshly distilled solvent prevents any loosened dirt from settling back onto the fabric. For extremely delicate pieces, we perform manual dry cleaning — applying and removing solvent by hand, section by section, with precision tools.
4. Pressing and Finishing. Clean garments are pressed on commercial-grade equipment using steam and, where appropriate, natural starch. We press from the inside out on dark fabrics to prevent shine, and use pressing cloths to protect delicate surfaces.
5. Quality Inspection. Every garment receives a final check for missed spots, wrinkles, and overall presentation. Items that do not meet our standard are re-processed.
6. Protective Packaging. Finished garments are hung on padded hangers, wrapped in breathable covers, and organized for easy customer pickup.
Machine vs. Manual Dry Cleaning
Most garments are cleaned in our machines — sealed, rotating drums that immerse clothes in filtered solvent and then recover the solvent through evaporation and condensation. This method is efficient, consistent, and suitable for the vast majority of dry-clean-only items.
Manual dry cleaning is reserved for pieces that cannot tolerate any mechanical agitation: heavily beaded gowns, antique lace, couture garments, or items with structural elements like boning or glued embellishments. In manual cleaning, our technicians apply solvent with soft brushes and absorbent cloths, working inch by inch. The garment is then air-dried on a form to preserve its shape. This approach is slower and more labour-intensive, but it gives our artisans complete control.
What Fabrics Need Dry Cleaning?
As a general rule, the following materials benefit from professional dry cleaning rather than home laundering:
- Silk — Weakens when wet; prone to water spotting and colour loss.
- Wool and cashmere — Shrink and felt when exposed to water and heat.
- Acetate and rayon — Can lose shape and develop water marks.
- Velvet — Water flattens the pile and is extremely difficult to restore.
- Structured garments — Suits, blazers, and coats with internal canvassing lose their shape in water.
- Leather and suede — Water damages the finish and causes stiffening.
- Garments with embellishments — Beads, sequins, and embroidery can loosen or melt in a washer.
When in doubt, check the care label. If it displays a circle (with or without a letter inside), the garment is meant for dry cleaning. If you are still unsure, bring it to any Royal Clean branch — our staff will inspect the fabric and recommend the safest cleaning method.
Why Professional Dry Cleaning Outperforms Home Methods
At-home "dry cleaning kits" have grown in popularity, but they offer only surface-level refreshing — they cannot match the deep cleaning, targeted stain removal, and professional finishing that a real dry cleaning facility provides. Home kits typically use a damp cloth with a mild solvent or fragrance in a tumble dryer bag. They may reduce odour and light wrinkles, but they do not dissolve embedded oils, remove perspiration salts, or address set-in stains.
Professional dry cleaning delivers complete soil removal, expert stain treatment, crisp pressing, and protective packaging — all handled by trained specialists using commercial-grade equipment and chemistry.
Dry Cleaning FAQs
Is dry cleaning safe for the environment? Modern dry cleaning has evolved significantly. At Royal Clean, we use non-toxic solvents and closed-loop machines that recover and recycle cleaning fluids, dramatically reducing environmental impact compared to older technologies.
How often should I dry clean my suits? In the Philippine climate, every three to four wearings is a good rule — or sooner if you notice stains, odour, or perspiration marks. Over-cleaning can wear fabrics prematurely, so balance freshness with longevity.
Can dry cleaning shrink my clothes? When performed correctly by trained professionals, dry cleaning does not cause shrinkage. Shrinkage occurs when fabrics are exposed to water and heat — precisely the conditions that dry cleaning avoids.
What is the turnaround time at Royal Clean? Standard service is two to three business days. Same-day and next-day rush options are available at select branches.
Caring for Your Dry-Cleaned Garments at Home
Even with regular professional dry cleaning, how you store and handle your garments between visits to the cleaner makes a significant difference in their longevity and appearance. Here are practical recommendations from our IFI-trained team:
Remove plastic covers after pickup. The plastic bags used when you collect your dry cleaning are designed for transport protection only — not for long-term storage. Plastic traps moisture and prevents air circulation, which can cause yellowing, mildew, and musty odours over time. Replace plastic with breathable cotton or muslin garment bags for closet storage.
Use shaped hangers. Invest in sturdy, contoured wooden or padded hangers that support the natural shape of shoulders. Wire hangers from dry cleaners are convenient but can distort garment shoulders and leave crease marks over extended use.
Allow garments to air between wearings. Before returning a suit or dress to the closet after wearing, hang it in an open, ventilated area for at least 24 hours. This allows perspiration moisture and body heat to dissipate naturally, which reduces odour development and extends the interval between professional cleanings.
Address stains promptly. If you spill something on a dry-clean-only garment, blot the spot immediately with a clean white cloth. Do not apply water, home stain removers, or soap — these can set certain stains or create water marks on solvent-cleaned fabrics. Bring the garment to Royal Clean as soon as possible and point out the stain to our staff so we can treat it with the correct chemistry before cleaning.
Store seasonal items properly. Garments that will be stored for an extended period — winter coats, formal wear, seasonal items — should be professionally cleaned before storage. Body oils and invisible perspiration residues left on fabric will oxidize during storage, producing yellow stains that are difficult to remove months later. Clean garments stored in breathable bags in a cool, dry, dark closet will remain in excellent condition indefinitely.
