Hand Washing involves soaking the item in water and detergent to gently remove soils from the fabric. This method is very restrictive, and has very little or no agitation.
Machine Washing garments are cleaned in a machine with water and detergent. Bleach and/or other laundry additives may be used. The garments are subjected to mechanical action by an agitator. Although there are several different cycles available on most washing machines, they are not as gentle as hand washing.
Drycleaning uses fluids to remove soils and stains from fabric. The term “drycleaning” is misleading; it is called drycleaning because the fluid contains little or no water and does not penetrate the fibers like water. Solvents currently used for drycleaning include perchloroethylene (“perc” for short) and petroleum. In most cases, garments are cleaned and dried in the same machine — they go in dry and come out dry. This process is followed by finishing procedures using special equipment, such as presses and puff irons.
