OK, here's the pitch: here in Germany all washing machines have
heating rods which heat the washwater to temperatures from 20 to 95° C
(= 70-200° F), with most of the washing done at 30 or 60° C (90-140°
The other day I heard a radio feature that most modern detergents work
well already at 20° C (i. e. normal room temperature), that the notion
that only hot washes were thorough was antiquated, and so much so that
in many parts of the world, such as Australia or the US, washing
machines wouldn't even possess heating rods at all, and just used
water at tap temperature.
So is that the truth, Ruth?
I'd specifically like to hear from Yanks and Ozzies, thanks.
australian person here:
yes, hot washes are mostly a thing of the past - cold washes work perfectly
well for most things & that's what people mostly do.
however, if you want or need to do a hot wash, you just set the machine for
a hot wash, to fill from the hot tap instead of the cold tap. a few
households (e.g. mine) only have a cold laundry tap so that's not possible,
but that's a bit uncommon too to only have one tap.
frankly, a machine that heats the water is the most odd thing i have heard
of for a while! not least because i was under the impression that germany is
a rather ecologically-responsible nation.
