We all have experienced flustering moments like in situations when white shirt gets ink on it, stew got on shirts and when coffee was spilled on skirt. These are certainly not desirable moments but we all know that most people try to get the stain off immediately not to leave a permanent mark by rubbing. This is where we got the idea for the invention of a thimble-type stain washer. It's used just like a thimber on a finger that controls power and direction. Movement of a finger washes more delicately than simple on/off of washing machine. Detergent and water are condensed in the form of a pill which is to be dropped in the machine in washing
