It’s not totally necessary but you’re using a fair bit of detergent if you’re not and making dish life a lot more difficult for yourself. You really should be if you can and as hot as you can stand it. Hot water alone is one of the best solvents out there, I even use it to help break clay down.
You don’t need hot water though? in my family, and guessing my entire culture, we wash with tap water and just scrub until it’s clean
You don’t need hot water, it just makes stuff more soluble faster, is more pleasant to wash with, and makes rinsing off the soap WAY faster.
Also, if you rinse off your dishes as soon as you’re done eating, or soak them in hot water, you barely need to scrub.
So, you don’t NEED hot water, it just saves a ton of time. I spend maybe 20 minutes a week total doing dishes. Having a dishwasher helps a lot, too.
