Development of an organic de-limer and polisher using the acid from averrhoa Bilimbi (Kamias Fruit): A sustainable solution for industrial cleaning

The central aim of this research was to explore the feasibility of utilizing an organic cleaning solution as an alternative to chemical agents for eliminating watermark stains on stainless steel kitchen countertops, windows, and equipment. The primary objective was to mitigate the adverse environmental impacts associated with descaling agents. The research employed an experimental design to test formulations of Kamias delimer solutions for their total acidity and the reduction of pathogens such as salmonella, E. coli, and staphylococcus. Maintenance employees and culinary students familiar with standard cleaning processes were surveyed to gauge their opinions on the product's use. Averrhoa bilimbi, with its high citric acid content, presented as an effective solution for removing tarnish, stains, and oxidation from metals, leaving a remarkable shine. The Kamias Delimer, with a total acidity of 5.69 pH, proved effective in reducing pathogens by up to 99.99% within a 10-minute contact period. Survey respondents positively endorsed the use of the kamiasdelimer solution. The findings from this research initiative will provide valuable insights in Barangay San Ildefonso, Alaminos Laguna, contributing to the development of eco-friendly and sustainable cleaning solutions suitable for the local community. This investigation adds to the expanding knowledge about sustainable cleaning methods, aiming to optimize the utilization of Kamias fruit.
