AJAR.id – Hello Ajarian! The choice of dry cleaning chemicals is very important. If the correct chemicals are not used, this may result in a large number of items needing to be rewashed because stains remain, adding to the overall cost of laundering linen. Using too little or too much chemical in the wash cycle may result in damaged linen and complaints from hotel guests.
The main types of chemicals used for dry cleaning are the dry cleaning fluids and the pre-spotting chemicals. The most common dry cleaning solvents in use today are:
- Perchlorethylene which is a non-flammable chlorinated solvent. It should be stored in a cool dark place when not in use. It is instrumental in removing solvent soluble soil such as oils and greases etc. It may however also dissolve decorative items on clothing such as sequins, beads, some buttons, and synthetic trims. This is the most common dry cleaning solvent in use.
- White spirit is an original dry cleaning fluid and has been widely used for many years. With the outlawing of fluorocarbons for environmental reasons, it is regaining popularity. It is a paraffin based spirit, has good grease removal properties but is flammable.
- Hydrocarbon is a petroleum-based solvent which is flammable. It is more suitable for use on delicate garments but needs a longer wash cycle to allow it to work.
