How Do Dry Cleaners Work?

At Readywear Cleaners, we get this question a lot: what actually happens to your clothes once they leave the counter? Dry cleaners use a specialized cleaning solvent instead of water, but the process involves far more than tossing garments into a machine. Each item is inspected, treated for problem areas, cleaned, dried, pressed, and inspected again before it comes back to you. Here's what actually happens, step by step.  

How Dry Cleaning Works Without Water

The biggest difference between dry cleaning and home washing is what's used to clean your clothes. Instead of water and detergent, dry cleaning uses a specialized liquid solvent to lift away dirt, body oils, and stains. This can be a better fit for wool, silk, tailored jackets, and other garments that may shrink, lose their shape, or change texture when exposed to water and agitation.

The cleaning solvent itself matters too. We use the GreenEarth® eco-friendly cleaning process, which uses a clear, odorless liquid silicone instead of PERC or petroleum-based solvents. Curious how GreenEarth's process specifically compares to older solvents? We've broken that down in a separate post.

The Solvent Cleaning and Drying Cycle

Once stains have been treated, garments are sorted by factors like color, fabric, and any special care needs rather than combined into one load. They then move into the dry cleaning machine, where they're gently tumbled in the cleaning solvent. As the solvent moves through the fabric, it lifts away body oils, dirt, and other soils. 

After cleaning, the solvent is extracted from the garments and the drying cycle begins. Warm air removes any remaining solvent, leaving the garments dry and ready for finishing. By the time they leave the machine, the cleaning solvent has been removed and recovered.

Not Every Item Goes Through the Solvent Cycle

Not everything that comes through our doors gets cleaned the same way. Items like cotton dress shirts are typically laundered — washed with water and detergent, much like a home washing machine — rather than run through the solvent cycle described above. The garment still goes through the same careful inspection, tagging, and stain treatment first, and the same professional pressing and finishing afterward; only the cleaning step itself is different. 

We've covered when a cleaner launders instead of dry cleans in our post on dry cleaning vs. washing at home, and a closer look at why professional shirt laundering beats home ironing is coming soon.
