 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.
