Should I use the sanitize option on my dishwasher?
When it comes to the sanitize option on your dishwasher, the short answer is yes, you should use it if available. This feature typically raises the water temperature or uses additional cycles to kill bacteria, making it especially useful for cleaning items like baby bottles and food storage containers. Sanitizing can help prevent the growth of harmful microorganisms that regular washing might miss, which is particularly beneficial for households with young children or elderly family members who may have weaker immune systems. To make the most out of this feature, it’s a good idea to run the sanitize cycle at least once a week or more frequently if there are concerns about germ exposure.
Can hard water affect the dishwasher’s ability to heat water?
Can hard water affect the dishwasher’s ability to heat water? Indeed, it can. Hard water contains high levels of minerals like calcium and magnesium, which can buildup inside your dishwasher over time, particularly around the heating element. This buildup acts as an insulator, reducing the dishwasher’s efficiency in heating the water to the necessary temperatures for effective cleaning. Consequently, the dishwasher may struggle to reach the optimal washing temperature, leading to less effective cleaning cycles. To mitigate this issue, regularly descaling your dishwasher with a suitable cleaning agent can help remove mineral deposits and keep the heating element functioning properly. Additionally, using water softeners or conditioners can significantly reduce the impact of hard water on your dishwasher’s performance.
