Items to Always Dry Clean You should not machine wash dry clean only clothing of certain types. Used filters are another form of waste as is waste water. You might, however, get away with a hand-washing in cool water, lay flat to dry. Other product and company names shown may be trademarks of their respective owners.
Why Clothes Are Labeled “Dry Clean Only”
The solvents are non-polar and tend to selectively extract compounds that cause stains. These stains would otherwise only dissolve in aqueous detergents mixtures at high temperatures, potentially damaging delicate fabrics.
Non-polar solvents are also good for some fabrics, especially natural fabrics, as the solvent does not interact with any polar groups within the fabric.
Water binds to these polar groups which results in the swelling and stretching of proteins within fibers during laundry. Also, the binding of water molecules interferes with weak attractions within the fiber, resulting in the loss of the fiber's original shape. After the laundry cycle, water molecules will dry off. However, the original shape of the fibers has already been distorted and this commonly results in shrinkage.
Non-polar solvents prevent this interaction, protecting more delicate fabrics. The usage of an effective solvent coupled with mechanical friction from tumbling effectively removes stains. A dry-cleaning machine is similar to a combination of a domestic washing machine and clothes dryer.
Garments are placed in the washing or extraction chamber referred to as the 'basket' or 'drum' , which constitutes the core of the machine. The washing chamber contains a horizontal, perforated drum that rotates within an outer shell. The shell holds the solvent while the rotating drum holds the garment load.
During the wash cycle, the chamber is filled approximately one-third full of solvent and begins to rotate, agitating the clothing. During the wash cycle, the solvent in the chamber commonly known as the 'cage' or 'tackle box' is passed through a filtration chamber and then fed back into the 'cage'. This is known as the cycle and is continued for the wash duration. The solvent is then removed and sent to a distillation unit consisting of a boiler and condenser.
The condensed solvent is fed into a separator unit where any remaining water is separated from the solvent and then fed into the 'clean solvent' tank. The ideal flow rate is roughly 8 liters of solvent per kilogram of garments per minute, depending on the size of the machine.
Garments are also checked for foreign objects. Items such as plastic pens that may dissolve in the solvent bath, damaging the textiles.
Some textile dyes are "loose" and will shed dye during solvent immersion. Fragile items, such as feather bedspreads or tasseled rugs or hangings, may be enclosed in a loose mesh bag.
The density of perchloroethylene is around 1. Not all stains can be removed by dry cleaning. Some need to be treated with spotting solvents — sometimes by steam jet or by soaking in special stain-remover liquids — before garments are washed or dry cleaned. Also, garments stored in soiled condition for a long time are difficult to bring back to their original color and texture.
A typical wash cycle lasts for 8—15 minutes depending on the type of garments and degree of soiling. During the first three minutes, solvent-soluble soils dissolve into the perchloroethylene and loose, insoluble soil comes off. It takes 10—12 minutes after the loose soil has come off to remove the ground-in insoluble soil from garments. A dry cleaning surfactant "soap" may also be added. At the end of the wash cycle, the machine starts a rinse cycle where the garment load is rinsed with freshly distilled solvent dispensed from the solvent tank.
This pure solvent rinse prevents discoloration caused by soil particles being absorbed back onto the garment surface from the 'dirty' working solvent. After the rinse cycle, the machine begins the extraction process, which recovers the solvent for reuse.
Modern machines recover approximately Until this time, the cleaning is done in normal temperature, as the solvent is never heated in dry cleaning process.
When no more solvent can be spun out, the machine starts the drying cycle. The air temperature is controlled to prevent heat damage to the garments.
The exhausted warm air from the machine then passes through a chiller unit where solvent vapors are condensed and returned to the distilled solvent tank. Modern dry cleaning machines use a closed-loop system in which the chilled air is reheated and recirculated. This results in high solvent recovery rates and reduced air pollution. In the early days of dry cleaning, large amounts of perchlorethylene were vented to the atmosphere because it was regarded as cheap and believed to be harmless.
After the drying cycle is complete, a deodorizing aeration cycle cools the garments and removes further traces of solvent, by circulating cool outside air over the garments and then through a vapor recovery filter made from activated carbon and polymer resins. After the aeration cycle, the garments are clean and ready for pressing and finishing.
Working solvent from the washing chamber passes through several filtration steps before it is returned to the washing chamber. The first step is a button trap, which prevents small objects such as lint, fasteners, buttons, and coins from entering the solvent pump. Over time, a thin layer of filter cake called "muck" accumulates on the lint filter. The muck is removed regularly commonly once per day and then processed to recover solvent trapped in the muck. Many machines use "spin disk filters ", which remove the muck from the filter by centrifugal force while it is back washed with solvent.
After the lint filter, the solvent passes through an absorptive cartridge filter. This filter, which contains activated clays and charcoal, removes fine insoluble soil and non-volatile residues, along with dyes from the solvent. Finally, the solvent passes through a polishing filter, which removes any soil not previously removed. The clean solvent is then returned to the working solvent tank. Cooked powder residue is the name for the waste material generated by cooking down or distilling muck.
It will contain solvent, powdered filter material diatomite , carbon, non-volatile residues, lint, dyes, grease, soils, and water. The waste sludge or solid residue from the still contains solvent, water, soils, carbon, and other non-volatile residues. Used filters are another form of waste as is waste water.
To enhance cleaning power, small amounts of detergent 0. These detergents emulsify hydrophobic soils and keep soil from redepositing on garments. Depending on the machine's design, either an anionic or a cationic detergent is used. It may have the letter P inside it to indicate perchloroethylene solvent, or the letter F to indicate a flammable solvent Feuergefährliches Schwerbenzin.
A bar underneath the circle indicates that only mild cleaning processes is recommended. A crossed-out empty circle indicates that dry cleaning is not permitted.
Dryclean, tetrachloroethylene PCE only. Perchloroethylene PCE, or tetrachloroethylene has been in use since the s. PCE is the most common solvent, the "standard" for cleaning performance. It is a most effective cleaning solvent. It is thermally stable, recyclable, and has low toxicity. In some cases it may damage special trims, buttons, and beads on some garments.
A number of dry cleaning alternatives have been released on the market in recent years, including home dry cleaning kits which allow you to do your own dry cleaning using a home dryer. These kits generally contain a pre-treating liquid which needs to be rubbed directly into stained areas on the garment or garments that you're cleaning, a cloth bag which can be placed in the dryer, and small sheets which are soaked in solvent.
The pre-treated clothes are placed inside the bag with a solvent sheet, and the bag is then placed into the drier for the amount of time listed in the kit instructions.
The heat of the dryer evaporates the solvent, causing it to react with the stains on the clothing and dissolving them. If the garment is not stained but has simply been worn, then it may be possible to steam clean it in the dryer as well.
Place the garment in the dryer along with a dryer sheet and a damp towel making sure that the towel is only somewhat damp and not overly wet.
The heat from the dryer will cause the towel to release steam, while the dryer sheet will reduce static and if you're using scented dryer sheets it will also leave your clothes smelling fresh. Some materials are also safe to wash after they have been dry cleaned once or twice If you attempt to try washing clothing after it has been dry cleaned a few times, make sure that you use the delicate cycle in order to help prevent any damage that might be done in case the material hasn't set.
Certain materials such as wool and very fine silk should be taken to the dry cleaner if it needs to be cleaned; wool can shrink horribly if washed in a standard washing machine especially in warm or hot water , and fine silk can be damaged by the agitation of your washing machine. You might also consider taking clothes that you would normally hand wash to the dry cleaner at least once in a while, if you feel that you need a break from your standard hand washing routine.
Just because some of your clothes are dry clean only doesn't mean that you have to take them in for cleaning every time that you wear them. Consider wearing a plain t-shirt or other basic garment that you can throw into the washing machine underneath your "dry clean only" clothes; this can help prevent perspiration and body soil from getting into the clothing, and can reduce the frequency with which you have to have it cleaned.
You also might wish to consider using some of the alternatives mentioned above on an occasional basis, alternating trips to the dry cleaner with cleanings done with a home kit or other alternative. Another option is to simply shop around at thrift stores or factory second stores Sign in or sign up and post using a HubPages Network account.

When hand washing your dry clean only items such as sweaters, always use cold water.. Good to know that "dry clean only" isn't always a mandate, that hadn't occurred to me.
Great posting, thanks for sharing. But now we can use a kind of dry clean alternative, fresh the "Dry clean only" cloth, it called freshcloz. I voted you up and useful! This article is very helpful, and now I am excited to get to wear my favorite things more often because I don't have to go to the dry cleaners once a month!
I would leave my work clothes for dry cleaning; it was more for the pressing than the cleaning. Love the baby picture. My mother told me it was common practice to sew in underarm pads into good dresses often wool - which were then removed and washed - rather than having to have the entire garment washed.
I wear eleaborate ballroom dancing dresses which are often heavily stoned with crystals. You never dry clean them - the stones fall off - instead you lay them flat and spot wash the underarms and other bits which get smellie.
