Eli5 Why does it matter what temperature the water is when we do laundry?

I’ve been a “throw everything in and wash on cold” person forever, but I started to notice certain things such as towels that typically require hot or warm water didn’t feel right anymore. Once I switched back they came out feeling soft and fluffy as usual. Why does it matter?

Laundry is as much a chemical reaction as it is mechanical agitation. A warmer chemical bath means superior cleaning action.

And as a frequently filthy trades guy, I am in the warm or hot laundry camp. Even with a modern efficient front loader you just aren’t killing off all that bacteria or dissolving stains with cold water.

If you don’t believe me, forget to put that laundry in the dryer and come back in 4-6 hours. The stuff you washed on warm will smell fine. The stuff you washed on cold will stink.
