Experimental Procedure

 Experimental Procedure Step 1: Begin by outlining multiple 10cm x 10cm  on a clean white cotton shirt using a marker, ensuring precision in your markings. Step 2: Carefully cut out the marked squares on the shirt, creating designated areas for stain application. Step 3: Delicately dispense 5 ml of red wine, 5 ml of coffee, and 5 grams of tomato sauce onto separate squares, ensuring even distribution for accurate stain representation. Step 4: Craft the homemade stain remover by combining a concoction of baking soda, liquid dish soap, and hydrogen peroxide in a bowl, blending the ingredients thoroughly to form a potent stain-fighting solution. Step 5: Employ three distinct stain removers—Bleach, Vanish, and a homemade stain remover—on each respective spill, allowing for a comprehensive assessment of their stain-removing capabilities. Step 6: Develop a nuanced and graded color scale for each stain remover, capturing the spectrum of stain removal effectiveness, ranging from mi...

Conclusion

 Conclusion After a series of tests on the effectiveness of different stain removers, namely bleach, baking soda and lemon, and soap and water, on various stains such as coffee, ketchup, and soy sauce, we have come to the realization that our hypothesis was incorrect. Bleach removes the stain but leaves a slight residue on the fabric. Baking soda and lemon worsened the stain; we tested this in two ways: firstly, by creating a homogeneous mixture of baking soda and lemon and applying it to the stain, and secondly, by applying baking soda first followed by lemon. Soap and water, which exhibited the most effectiveness, involved applying the soap, scrubbing, and then rinsing with water to remove the soap. As a recommendation, I would suggest allocating more time and organizing the process more efficiently for future experiments.

Abstract

 Abstract Stains are a common household challenge, but with the right approach, they can be effectively removed. This project investigates the science of stain removal by examining the reactions of different types of stains to bleach and homemade stain removers. Through carefully controlled experiments, utilizing coffee (protein-based), soy sauce (oil-based), and ketchup (pigment-based) stains, we observed the effects of bleach and homemade stain removers over time. Our results indicate that while bleach showed efficacy in some cases, homemade solutions, particularly a combination of soap and water, demonstrated superior effectiveness overall. This study provides valuable insights into the chemistry of stain removal, offering practical solutions for tackling stubborn stains in everyday life.
