I investigated if more expensive laundry detergent was better at removing stains then a cheaper one or any detergent at all. I tested if Woolite detergent was the same, better or worse then tide detergent at taking out a fresh coffee stain. How do the two detergents compare to just water? There was a significant difference between the cloths that were washed detergent to rather being washed in only water. After the clothes were taken out of the solutions and dried I was able to see that there was a slight but noticeable change between the Woolite and Tide detergent and a very significant change compared to the water.After conducting this experiment I believe the more expensive detergent had the best results.
