This study compares four home dish soaps for cleaning. Dawn Ultra, Palmolive, Gain, and Ajax dish soaps are under scrutiny. A simple wash test, possible hydrogen testing, and dish-drying bacterial growth will compare their cleaning ability. Dish soap should remove stubborn grease and prevent animal oil contamination. Dish soaps with a pH lower than 9-10 are less effective. Dishes may still contain stomach-irritating microorganisms like E. coli and Salmonella after cleaning. Foodborne pathogens may stay on plates after washing, and towel-dried words have more germs owing to pre-contaminated towels. A consistent approach will evaluate each dish soap’s cleansing and bacterial growth. After pH testing, each soap will wash dishes with the same food residue using distinct sponges. A cloth mat will dry the dishes. To cultivate bacteria, sterile swabs will gather and streak bacterial samples onto agar plates for 24 hours. Counting bacterial colonies on each vessel will provide quantitative data (Central et al., 2019). This research compares four dish soap’s bacterial growth and cleansing capability to find the best one. The data will help choose the finest dish soap for successful dishwashing and home hygiene.
Methods and Experiments
In this study, the cleaning efficiency and capacity to reduce bacterial growth on dishes of four different dish soaps—Dawn Ultra Dishwashing Liquid Dish Soap Original, Palmolive Dish Soap Original, Gain Dishwashing Liquid Original, and Ajax Dishwashing Liquid Soap Yellow Lemon—was assessed. The experiment’s three main parts were a real wash test, potential hydrogen (pH) testing, and bacterial collection and analysis. To start, the basicity of each dish soap was assessed by measuring its pH on litmus paper. A dish soap was deemed successful if its pH was between 9 and 10 since a lower pH might mean less effective cleaning.

The same food residue was created in four identical containers, each dirty. Each dish soap was given its own dish sponge to provide a fair comparison. The dishes were cleaned with the same quantity of soap in water that was kept at a constant temperature of 80 degrees Fahrenheit for a predetermined period—one minute (Jamaludin & Deurenberg, 2020). To determine the effect of the drying technique on bacterial growth, the dishes were air-dried on a fabric mat after being washed. Due to pre-contaminated towels, towel drying was found to have a greater possibility for bacterial contamination, while air drying was anticipated to result in less bacterial development.
Sterile swabs were used to collect bacterial samples from each plate after it had dried by air drying, swabbing each surface for around 30 seconds. The four-quadrant approach was used to streak the swabs onto agar plates. Bacteria were allowed to grow for 24 hours on four agar plates, one for each kind of dish soap. The agar plates were checked after incubation to see what types and how many bacterial colonies had grown. Bacterial growth on each scale was quantified by counting the number of bacterial colonies (Josep, 2021).
Standardized controls were used in the experiment, including the exact water temperature, equal time spent washing dishes, and a fixed quantity of each soap. Easily accessible home goods and dish washes from stores were used in the investigation, which cost $27.48 in total in supplies. This research attempted to identify which dish soap demonstrated the most efficient cleaning power and the least amount of bacterial growth after drying by comparing the cleaning efficacy of the soaps and measuring the bacterial growth on the agar plates. The results provide helpful guidance for choosing the best dish soap for everyday usage in the home, considering both cleanliness and bacterial control.
Discussion and Result
Analysis has been done on the findings of an experiment comparing the bacterial control and cleaning power of four dish soaps: Dawn Ultra Dishwashing Liquid Dish Soap Original, Palmolive Dish Soap Original, Gain Dishwashing Liquid Original, and Ajax Dishwashing Liquid Soap Yellow Lemon. The dish soap’s cleaning efficacy was assessed based on how well they cleaned stubborn grease off dishes and animal oil splatter (Josep, 2021). The experiment used the same quantity of each soap and the same water temperature, washing soiled dishes for one minute. The findings showed that Dawn Dish Soap, made primarily for cleaning difficult grease and oil pollutants, worked very well. Although not as effective as Dawn, Palmolive, Gain, and Ajax also displayed acceptable cleaning efficacy.

According to the results of the pH tests, Dawn Dish Soap has a little higher pH than the other three soaps. This suggests that Dawn is more basic, consistent with the pH range anticipated for efficient dish soaps. The proper pH levels of Palmolive, Gain, and Ajax indicated their potential for cleaning effectiveness. The agar plate technique was used to evaluate the development of bacteria on the cleaned and air-dried plates in terms of bacterial control. The bacteria colonies were observed and studied 24 hours after incubating the agar plates.
The results showed that all four dish soaps had some degree of success in controlling bacterial growth. On the other hand, Dawn Dish Soap showed the fewest bacterial colonies, demonstrating its greater capacity to reduce bacterial contamination on plates (Trupp Gil, 2018). According to the testing results, Dawn Ultra Dishwashing Liquid Dish Detergent Original was the best dish detergent for cleaning and bacterial control. While limiting bacterial development, it effectively removed challenging grease and oil pollutants. Despite having a respectable performance, Dawn outperformed Palmolive, Gain, and Ajax. These findings provide customers with helpful information to help them choose the best dish soap for their requirements. For people looking for a dish detergent with exceptional cleaning power and bacterial control, Dawn Ultra Dishwashing Liquid Dish Detergent Original is advised.
