Why does water temperature matter when washing clothes?

420 views

Visiting my parents, my mom seems disappointed to find me washing my clothes in cold water, she says it’s just not right but couldn’t quite explain why.

I’ve washed all of my laundry using the “cold” setting on washing machines for as long as I can remember. I’ve never had color bleeding or anything similar as seems to affect so many people.

EDIT: I love how this devolved into tutorials on opening Capri suns, tips for murders, and the truth about Australian peppers

Once upon a time, detergents didn’t work so well in cold water. Washing machines had cycles like “Cotton 140F” and “Delicates 100F” and that was how your mom grew up. If you washed in cold water it didn’t work well at getting your clothes clean, and it didn’t rinse well either.

Since she grew up there have been huge improvements in detergent efficacy and you can wash really well in cold water, which is much cheaper for your energy bill and better for the environment too. Far from doing something wrong, you’re doing it right!
