2. Main Wash
This is where the bulk of the cleaning happens. The dishwasher jets spray hot water mixed with detergent, effectively removing grease and grime.
3. Rinsing
After the main wash, the dishwasher rinses the dishes with clean, hot water to remove soap residue.
4. Drying
Finally, some models include a drying cycle that uses a small amount of water to create steam, helping to eliminate any leftover moisture.
Water Usage of Hand Washing
On the other side of the spectrum is hand washing, traditionally considered the go-to method for many households. However, this method can vary greatly in terms of water usage:
The Hand Washing Process
When washing dishes by hand, the amount of water used can differ significantly based on the technique and mindset of the individual doing the washing:
1. Continuous Flow
Many people leave the tap running continuously, which can waste as much as 8 to 10 gallons of water per load.
2. Fill-and-Soak
Some environmentally conscious individuals fill one basin with soapy water and another with rinse water. This method can use about 3 to 7 gallons in total.
Comparative Analysis: Hand Washing vs. Portable Dishwashing
When we analyze the water usage of both methods, the following picture emerges:
