Some times of the year I couldn't wash in 20°C water unless I refrigerated it first for a while. Tap cold at the moment is running 31°C.
Would you wash at 20?

About the notion that top loaders use 'extremely' large amounte of water - that is nothing more than a moot point. On the basis of that argument it would then also be fair to say that modern front loaders and other high efficiency machines are performing less than optimal due to insufficient water use. In the past, European front loaders used up to 160 liters or more per cycle, to wash and rinse 4.5 to 5 kg of laundry.
This would sum it up better for me
"Hygienic quality of washing at lower temperatures
The results show that the hygienic quality of the washing processes at low
temperatures (i.e. 15°C and 30°C) leaves something to be desired. A small
reduction of the Total Plate Count is achieved only in some cases. The contamination
level after washing is still relatively high. A significant temperature
effect on the hygienic quality is found (ANOVA-One Way, á = 0.05):
from a hygienic point of view a 30°C washing process is better than a 15°C
washing process. There is no effect of the bleaching agent on the hygienic
quality. The hygienic properties of the detergents in the dosages used have the
same level in the four European countries. No significant differences were
found at 15°C and at 30°C."
"A very general finding in this research is that in daily laundering, the cleaning
properties expressed as washing efficiency are worse at lower temperatures.
Lower temperatures mean lower hygiene levels. This is due to reduced germ
elimination combined with increased cross-contamination."
"The boil wash laundering process, which was used traditionally, showed appropriate
cleaning properties combined with excellent hygiene efficacy. As
mentioned in the previous sections, lower wash temperatures result in lower
hygienic quality. Thus it may be assumed that for domestic textile laundering
the measures to reduce energy consumption may have stressed the conditions
for proper hygiene."
But, as with any studys or statistics one is always free to pick out only the parts that suit oneself *LOL*
I wonder if in Spain might be higher concentations of chlorine in the tab water as an explanation for the different results besides the high sudsing detergents and possible extra rinses.
I also found it little surprising about liquid detergents` rinse efficiancy. We all know that liquids have a much lower pH when they contain enzymes than any heavy duty powder. So of course the risidual alkalinity test shows better results for the liquids...

I washed at 20-
had to, because at 20, I was at university in the halls of residence.
I even washed at 11, to relieve my hardworking mother of a big task she found sometimes burdensome.
Contact time, activity, temperature, and chemicals all have to be balanced for a good wash. Lee McMichael/Mac said it, Our darling Laundress says it, and I believe it. That should settle things.

Don't come the raw prawn with me...
...and then LOL me.
If I picked out the parts that I liked best, what did you do? Just like you, I cut and pasted part of the report's summation without altering the words. It's there for everyone to read and draw their own conclusions.

No offence intended at all !
It was exactly my point that everyone draws their own conclusions by reading what they want to see and overlooking what they don`t like. I didn`t say I was better than anyone else in this perspective.
Again no need to feel attacked.

@rapunzel: You just cant compare these washers with todays ones. But if you say that these are not your points, why do you say we have to depend on the washer type? And on, after i took my statement, you again say that we dont have to take the type of washer into view because there were washers 40 years ago which used even more water. We are talking about today. Washers made 40 years ago are a moot point, too. Both US and EU washers washed at higher temperatures 40 years ago, but the amount of water AND the temperature was reduced over time in the EU, but US still common type of traditional toploader still uses the same amount of water. And on, when did I say that EU has higher hygenic standards that the US? And as you told mrboilwash, everyone can draw their own conclusions.
And now a fact: YOU told BY YOURSELF: Extra rinses give better hygenic results. An extra rinse uses more water to solve all kind of bacteria and rinse it away. So why is it a moot point to say US toploaders use more than twice as much water? And again, espacily becaus EU frontloaders use lower amounts of water, you need a higher temp OR more chemicals OR longer washtimes to get the same cleaning results.

washers depending on where they are made are diffrent
rapunzel i have read the article seems that article dates from 2003 not all washers are made the same each brands are unique and if you look at us top load washer not all washers have an extra rinse option me in my case i had a set like this from 1993 to 2004 it was a direct drive washer and i did not have an extra rinse option and washing machines with years the model changes so in a way you might have what is top of the notch in your brand of washer for the current 2012 2013 years of production but that do not mean that next year the same washer you have same model will be its like the us canadiens washers if you look at the top load models of today the temp is dumb down like what was a true hot water before the changes in energy star qualification might be warm today warm water on today might be cool water and there auto cold with the possibilaty of hot water adding to disolve detergent and there tap cold for true cold water wash.

I wouldn't
20 degrees is grose, 40 for colours and whites and 60 for Towels and Sheets.
I only use 30 for something that I have only worn once.
I use Gels for Colours and Powders for Whites/Sheets and Towels.

That's just how i do it. But, of course, 30° for some delicate stuff and wool.

washing in 20c/68F . . . . . . I can just imagine what all
Are there any these days??

Nappies
Lots of them, big business these days given the non eco disposable variety...they do reccommend washing @ 60d.....
60d and 40d for me with an occasional 90d

Another past blast !!
When I was a young Father of two back in the late 80,s we determined then it was cheaper to use the washer and dryer every other day than to buy disposable nappies, it also saved having to go down to the bins too often as we lived in a first floor flat, I believe it was washing those pesky critters that killed our beloved Servis Quartz...
