2. Identification of the stain
Based on Colour clue.
Blue, black or red may be ink-stains.
Reds or pinks may be lipstick, rouge or nail polish.
Based on Appearance
Wax and paint stains build up on the surface of the fabric.
Oil and fats cause transluscent stains.
Medicine stains, food stains, and perfumes may leave specific odour.
Based on Touch.
Stickiness may be due to gum or glue, stiffness may be egg or some
other albuminous stain, paint may give a smooth feel.
In sophisticated laundries stains can be identified by X-ray diffraction
and other methods.

What is not said on a care label is also important.
If the label does not say that you cannot do something, you can assume that you can
do it.
For instance, if a care label gives washing instructions but does not warn against dry
cleaning, you should be able to dry clean the garment.
Some retailers have their own care-labeling programme. One consists of a simple
letter code that identifies five basic cleaning methods.
MH Machine wash hot. Tumble dry.
MW Machine wash warm. Tumble dry.
MG Machine wash gentle. Tumble dry, low heat.
HW Hand wash warm. Line dry.
DC Dry clean only.
