The fundamental difference between dry cleaning and laundering is water; dry-cleaning does not use water, while laundering on the other hand, does.
The dry cleaning process is done with a non-water-based cleaning solvent to remove stains and grease from clothing.
Laundry – also called wet cleaning – uses cleaning agents such as soaps, detergents, or softeners, along with water to remove any dirt from your clothing.
Another important difference is fabric. Dry cleaning is typically more gentle on fabrics and targets certain types of stains.
