Claims (24)

1 . A stain removal system for treating a stained area on a cloth, the stain removal system comprising:

a container for containing a bleach chemical, wherein the container is a removable cartridge;

a system for carrying the bleach chemical to the stained area under a liquid form; and

a light source for generating light radiation over the stained area.

2 . The stain removal system as claimed in claim 1 , wherein said light source is a light emitting diode (LED).
