Dry Cleaning - contrary to the misconception, this mode of cleaning is not dry but involves incorporation of other mediums (solvents), rather than water to clean fabrics. Solvents in dry cleaning are less reactive and milder in terms of cleaning providing a cleaning solution for fabrics susceptible to water. Contrary to wet cleaning, dry cleaning is a closed system and the solvent is filtered and reused.
Prominent solvents in the industry are:
- Perchloroethylene: known as Perc is a hydrocarbon based solvent identified on care labels as ? widely used due to high reactivity with oil stains which can be boosted by special detergents and sizing agent providing the best cleaning amongst all other dry cleaning solvents with a very small limitations.
- Green Earth: a patented technology developed by Green Earth utilizes silica based solvent – being totally inert – means chemical reactivity is at zero and only acts as a medium – cleaning is boosted by detergents and other additives. It can clean all those items that cannot be cleaned in normal dry cleaning and wet cleaning. It is as well much friendlier for environment compared to Perc due to its nature but much weaker in terms of cleaning and oil stain removal.
Normal washing (Laundry) - as known to everybody, involves the use of water and detergent to clean garments. Factors involved in such procedure are:
- Water – as the best medium being the best solvent with high chemical reactivity and the ability to penetrate in the fabric resulting in best cleaning
- Water Temperature – the higher the temperature the better cleaning result with more possibility of risk
- Alkalinity – the higher the PH, the better the cleaning with increased risk
- Mechanical action – the more mechanical action, the better cleaning with higher risk to the fabric
- Detergent – reacts readily with water facilitating removal of dirt from fabric
Wet cleaning (Soft wash) : This terminology stands for a new technology which creates a milder environment for garments to be cleaned with much lower risk of damage worthy of following notes:
- Water – in this technology, water is softened to almost distilled water helping to dramatically reduce its reactivity resulting in much lower risk
- Water Temperature – is reduced to around 20°
- Alkalinity – kept at PH level 7-8, most neutral
- Mechanical action – is reduced dramatically
- Detergent – is the most sophisticated part of the technology whereby coats the fabric during cleaning cycle stopping water from penetrating into the fabric minimizing shrinkage and other possible risks
