Abstract
This project was done to enhance an individual image through body scent. Past odour-related journals were analysed and found that the bacteria and mildew are the cause of the odour. Hence, this current study aims to investigate the effectiveness of the sunlight in removing the odour and mildew and finding alternatives in replacement of sunlight by using salt, vinegar and baking soda. In the experimental procedures, dynamo was added to five sweaty shirts. Salt, vinegar and baking soda were then added to the three shirts respectively during washing. Repeatedly, the experiment was carried out in sunny, cloudy and windy conditions to obtain a better accuracy in results. The comparisons were then made between the shirts dried under sunlight and the shirts which were added with additives, dried indoor with proper ventilation. It was observed that the shirts laundered under sunlight were in absence of odour and mildew. Similarly, the three addictives were able to remove the odour and mildew under the condition without sunlight and vinegar was found to be a stronger additive, followed by salt and then baking soda. In short, sunlight, vinegar and salt were more effective than baking soda in inhibiting the growth of mildew and bacteria and eliminating the odour from washed clothes. The obtained results will allow households to have better alternatives during rainy days to remove the odour of washed clothes. Lastly, future research can focus on the identification of mildew on washed clothes in the interests’ of the society.

1. Introduction
1.1 Background Information
With society becoming more modernised, most people are becoming more aware of their personal image. One of the many important factors that contribute to personal image is body scent. It allows people to present themselves better in front of others. [1] On the other hand, body odour is almost a certainty to lower one’s personal image. It is thus necessary to consider body odour along with personal style and appearance. Body odour, or body smell, is caused by bacteria growing on the body which multiply rapidly in the presence of sweat. [2] It is a natural process involving sweat that occurs on the skin's surface. Though sweat is odourless, when it is left on the skin, bacteria that also exist on the skin will feed on the sweat and break it down. This process releases chemicals that cause an unpleasant smell. Scientific study has shown that some areas of the skin, such as the armpits and genitals, are more likely to produce body odour because these glands...
