It is still the case here. I live in SA.
A lot of people have top loaders (and even twin tubs), and these don't heat the water. If you want a hot water wash, it would have to be plumbed to a hot tap, but most people don't do that. It is a case of take a bucket and fill it with hot water and pour it in, if needed.
So mostly all the washing is done in cold water.
Everything gets washed perfectly fine and not one person I have ever known (and I am in my mid 50s) has ever ailed from washing laundry in cold water. I did refer to different detergents upthread. If you are using a cold fill non heating machine, then the more foamy hand wash powder would be the one to use.
Of course many people have an auto front loader, but these get run on quick washes or 40 max. I have never washed any washing on 90 degrees.
I always read threads here saying things have to be washes on 60 or 90 because.... no, they really don't. It it just taking extra energy and most of all, time.
Granted though, we do hang our washing out on line to dry 99% of the time. Perhaps that makes some difference?
