At some point (in a galaxy, long long time ago) I learned to turn jeans, shorts and hoodies inside out when putting them into washing machine. For some reason, I don’t do the same with smaller, simple things like T-shirts and underwear.
I forgot what was the reasoning behind it, but when I think about it, can’t seem to come to a conclusion which way is better.
Is one way better than another and why?
Generally you want the dirtiest part on the outside. I find for things like jeans, I leave them outside-out; T-shirts are often inside-out.
The other reason to turn things inside-out is if there are designs or other features that you want to protect.
In short, whatever is on the outside is going to get the “rougher” treatment.
