When you can’t decipher the dots, lines and symbols on your favourite dress or that special suit you book a slot, we come to collect your clothes.
You can then get on with the rest of your day while we dry clean, press, finish and redeliver your laundry back to your doorstep.
But have you ever wondered how we take out those stubborn stains and revive your beloved clothes, reminding you why you fell in love with them in the first place?
Many of us may view dry cleaning as a modern convenience but believe it or not, dry cleaning is older than you think it is. As with any story arising out of the Ancient times thus comes a fascinating one. This tale of evolution calls on the collection of buckets of urine from Roman bathhouses to popping into your local dry cleaners.
Before cleaning, each garment is individually inspected and classified, dependent upon the type of article and the degree of soiling. A great deal of effort goes into the complete process and there is a handful of skilled professionals involved in caring for your garments behind the doors of our operation centres. You can explore the entire process here.
For more on what exactly ‘dry cleaning’ is, you’re in the right place.
Contrary to its title, dry cleaning isn’t entirely a ‘dry’ cleaning. Chemical solvents are used instead of water to dissolve and remove stains. The industry’s most popular solvent used is PERC, also known as Tetrachloroethylene or under the systematic names of Tetrachloroethene or perchloroethylene. PERC is a chlorocarbon with the formula of Cl2C=CCl2, It’s a colorless liquid and has a sweet scent. Other cleaning solvents also used include Hydrocarbon, Dibutoxymethane, Liquid silicone, Brominated solvents, Supercritical CO2, Glycol ethers and a handful of Modified Alcohols.
Still the preferred solvent in the dry cleaning industry, Tetrachloroethylene faces both environmental and health and safety regulations which will see Britain following in the footsteps of Germany and the US by banning its use and adopting new environmentally friendly practices.
Dry cleaning machines are diversified, but despite their differences they all perform on the same principle and function.
A dry cleaning machine is formed of four basic components:
Tank – This is where the dry cleaning solvent is held.
Pump – Until it is pumped through the machine.
Filter– Here filtration is used to separate and collect solid impurities.
Drum – Stainless Steel and perforated, this is the core of the machine where the load is placed to be cleaned.
The process of the dry cleaning machine is a simple one that may seem quite familiar to you.
At 30°, the solvent is drawn from the tank by the pump. The pump pushes the solvent through the filters to separate, collect and trap any impurities.
The filtered solvent will then run into the drum and fill around one-third of the drum, flushing soil from your garments while the ribbed drum walls rotate and gently lifts and drops the garments.
The unclean solvent is continuously drained back to the tank. It is filtered and pumped back into the drum, thus beginning the cleaning cycle. This is repeated for the duration of the 8–15 minutes (or 25 minute for hydrocarbon solvents) cycle.
In the first 3 minutes solvent soluble soils dissolve and loosen. It then takes 10-12 minutes for the removal of the more stubborn ground-in solubles.
At the end of the cleaning cycle the solvent is then drained into a distillation unit made up of a boiler and condenser before it is fed back into the tank as a fresh distilled solvent.
Rinsing with this solvent prevents discolouration caused by soiled particles being absorbed back onto the garment surface from the solvent while it is unclean.
Following this, the solvent is drained during an increased speed of rotation known as the extraction cycle to expel excess solvent from the clothes.
Here, the solvent is drained back to the tank and is recovered for reuse.
Modern machines recover approximately 99.99% of the solvent as the accelerated speed allows the solvent to spin free of the fabric. Until this time, the cleaning is done in normal temperature as the solvent is never heated in the dry cleaning process. Once all solvent has been removed the machine will start a drying cycle of 60-63° degrees where warm air circulates through the cylinder, vapourising the remaining fumes and solvents. The solvent vapours are then purified, heated and then condensed over cooling coils back to liquid form so it can be pumped back into the tank.
Once the drying cycle is complete, an aeration (deodorising) cycle cools the garments. It is removing any residue of solvent by circulating cool air in the drum over your garments, after this your laundry will be clean and ready for pressing and finishing.
It’s an industry established fact that the quality of cleaning, degree of soil removal, color brightness, odor and softness all hinge on the comprehensiveness to which the dry cleaner controls his filter, solvent condition and moisture. Quality control is interchangeable and can vary day to day so it’s only right to go with a reputable industry professional by leaving your precious garments safely in our expert hands.
