Senior High School, College of Education, Cavite State University, Indang,<br/>Cavite. May 2019. Adviser: Mr. Oliver P. Matunog<br/>This study was conducted from January to May 2019 among 30 housewives from Indang,<br/>Cavite to formulate a rust stain remover from the different treatments of pomelo extract, white<br/>vinegar, and salt and test its effectiveness with rust stain on white fabric. Specifically, this study<br/>aimed to: 1. determine the ability and effectiveness of pomelo extract to remove rust stain from<br/>white cotton fabric; 2. determine which among the three treatments is the most effective in<br/>removing rust stain on white cotton fabric; 3. determine the consumer's sensory evaluation and;<br/>4. determine the consumer's level of acceptability/satisfaction, and its potential for marketing.<br/>This study employed experimental research design because the study needed a scientific<br/>approach to be conducted, wherein a set of variables are kept constant while the other set of<br/>variables are being measured as the subject of experiment. Mier conducting the study, the<br/>researchers have formulated a rust stain remover from the different treatments of pomelo<br/>extract, white vinegar, and salt. It showed that the treatment that has the highest amount of<br/>pomelo extract appears to be the most effective in all the treatments. It appears that the smell of<br/>vinegar caused the sour odor of the rust stain remover and the number of pomelo extract mixed<br/>in each treatment affected its ability to remove rust stain from white cotton fabric<br/>Based on the results of the study the following recommendations were made to include<br/>the pomelo peels in extraction process so that the acidity level of the produced stain remover<br/>will increase thus, making it more effective; test the chemical properties of the product to further<br/>improve or increase its shelf life; further study should be conducted in order to test its capability<br/>to remove different kind of stain like ink, food oil, etc. and; have a larger population so that the<br/>data to be gathered will be more accurate.
