Final answer:
To properly clean cutlery, Shawn should scrape leftovers off before washing, use specific dishwasher detergent, and arrange items for optimal water flow. Vinegar can be used to clean lime buildup on appliances. Water alone doesn't remove oil from dishes due to a lack of detergent.
Step-by-step explanation:
When it comes to cleaning used cutlery, the correct process involves specific steps to ensure they are adequately safe and clean for their next use. Initially, Shawn should scrape leftover food from the dishes before placing them in the dishwasher. He must arrange the cutlery in the dishwasher in a manner that allows the water to flow freely over the surfaces of each item. Utilizing a special detergent designed for dishwasher use is essential in this process.
When Shawn notices a lime buildup on some kitchen equipment, the solution to cleaning it involves running vinegar (dilute acetic acid) through a cycle to dissolve the deposits. This method is particularly effective for appliances like coffee makers where lime can slow down the brewing process. It is crucial, however, to ensure that the equipment is rinsed thoroughly with water afterward to prevent any remaining vinegar from affecting the taste of beverages.
Regarding the question of why water alone was not effective in cleaning an oily salad bowl, it's important to understand that oil and water do not mix. The presence of an oily film after rinsing indicates that there was no detergent to emulsify the oil, which would allow it to be rinsed away effectively by water.
