The same, it needs heat. I seem to remember you saying before that you use cold water in NZ in your washers. IMO cold wash doesn't shift bio stains like sweat very well. I
try to wash a lot of our stuff on 30 degrees, but sheets flannels and towels go on 60 to kill the germs and dust mites, and anything that seems sweaty goes on 40 at least, maybe even 50........
Oh and I have one of those stain removing sprays that I use before stuff goes in the machine.....great for stuff like this
I use a Vanish one, but am not sure what brands you get there?
