What? No more warm water?

[yogitunes]

this is not 1963, nor are you washing clothing from 1963, or using detergent from 1963.....just the machine!

detergents and materials have obviously changed drastically....

not saying that I would wash in COLD either......

we did wash in Luke Warm water in the 70's when COLD POWER was available for saving energy.....

but with a HE machine, the most your using in a HOT wash is a few gallons, more than enough saving right there compared to a 20 gallon tub of regular TL machines...

I would love to have all those temp options. But notice how 'Cold' is 85ºF? Most new machines are below 70ºF on cold now. That won't cut it on 90% of our loads of laundry. They claim there is no difference in cleaning. I beg to differ.

It will be interesting to see if this ever catches on, especially in Europe.

A couple of thoughts:

Tide is expensive and not everyone can afford it on a limited budget. I personally have sworn off P&G products, and have for a number of years, as I don’t trust the chemicals they use. Last 2 times I used Tide I broke out in painful hives that took a week to get rid of. Never again.

In 2018 I made an extensive trip to visit relatives, I wrote about the experience when I started a thread about visiting relatives. The most disgusting towels and sheets that was offered to me had been washed in a lower shelf detergent and cold water. NOTHING smelled remotely clean, so much so I slept in my jeans and day clothing at one household. Towels smelled like soured vomit. Of course I was gracious and said nothing. Couldn’t wait to get to a motel.
All of this cold water bit reminds me of the energy crisis of the early / mid 1970’s when people started washing in cold water.....and some never went back. Hence the older relatives in my family.

Lastly, I’m thinking of staph infections, jock itch, athletes foot, kitchen towels, bath towels, bacteria. Need hot water for that.
My 2 cents.

Hell, I don't even rinse in cold. Warm always. Cold water here during the winter comes out virtually frozen from the tap.

 

 

[ozzie908]

So would a warm rinse

Equate quicker drying? Also if you have a machine with a spray and then deep rinse surely warm rinses remove suds easier as the threads of the garments are more relaxed???

Just my 2cents

Not feeling oats again

this morning, I use hot water if not the "STEAM" option usually. That is not a boil wash, but hot enough to stave off bed bugs and the like I presume.

 

[foraloysius]

Dust mites are stubborn cooties. If you really want to get rid of them, the temperature of the wash needs to maintained for an hour at 140F. That's without the effect of the detergent, but some detergents are better at killing dust mites than others. Steam may help, but it's the temperature of the laundry that counts in the end.

Warm Rinse

I remember Hoover-Candy had a 'Quattro' frontloader - I think it was - which had a warm final rinse before the spin cycle. It was supposed to give a better spin efficiency. This was around the time when 1600rpm was still only a 'B' grade efficiency on some manufacturers' machines.

Warm rinse

Commercial/industrial laundries most always use warm water for rinses. IIRC rationale is that chemicals and other substances flush more easily out of fabrics in warm water as opposed to cold. The latter causes textile (natural at least like cotton or linen) to constrict which could trap things in fabrics.

There is also the theory that more water is extracted from fabrics at warm versus cold. Finally laundry emerging warm from washer uses less energy for driers or ironers since neither has to deal with warming up "cold" laundry.

Read years ago in Consumer Reports that while yes, warm water rinsing is slightly better for tumble dryers, the higher cost of using heated water versus dryer having to run a bit harder initially to warm "cold" laundry negates any benefits.

Warm rinse option was common on American washing machines until 1970's or so; then energy crisis and tree huggers got at manufacturers and thus it has all but vanished.

Cold Wash: Not a chance!

My SQ FL does 99% hot (140 water washes) with an occasional warm. This cold wash bullshit is nothing but that.

Won't use Tide, will use warm/hot.

p.s.- Gansky- is that a 1900 series Novatronic?

 

[pierreandreply4]

i can't use tide anyway

i had to switch brand i can ot use tide anyway give me rash on my skin and smell is to strong i switch to la parisienne and sunlight

 

[petek]

I also can't use Tide because of itches and rashes.

Current tap temp in CF

Would any of you use this cold water for a wash? I certainly wouldn’t but there are thousands of people who unknowingly do.

 

[adam-aussie-vac]

Now, you’ve got me thinking if there are such things as

Warm rinse, and cold rinse, why not a hot rinse?

 

[mrboilwash]

Some early European automatics (Constructa?) had a separate built in boiler tank to provide hot water for a hot-warm-cold rinse procedure at a time when soap based powders were still king.
Americans seem to have always been more practical in terms of cutting unnecessary corners.

Warm rinsing

Energy efficency wise, it is pretty much the worst thing.

In todays laundry there are very few reasons to put up that energy.

Laundry is all about dissolving things into other things.

Warm water is better at dissolving stuff in general.
So a warm rinse is technically better at rinsing.

However modern detergents rinse very easily.
They are basically 100% dissolvable, they don't produce solid seperates like soap used to (soap scum etc.).

So even there, a proper extra rinse and enough agitation are usually better.

Warm rinses do help with extraction.

Miele professional over here lists extraction performance for warm and cold rinsing, and rinsing in warm water usually drops residual moisture by 4-8% from what I remember.

That can be helpfull if warm water is readily available, cheaply heated, laundry goes into the dryer ASAP and if dryers run on suboptimal fuel (electric resistive).

Otherwise it can waste time if water needs to be heated first and expensive if you let the laundry cool or water is heated expensive.

I know of 2 companies that offered warm rinses in the EU:

LG and Whirlpool.

LG called it "Medic Rinse" and Whirlpool just "Hot Finish".

My LG needed 20min to heat the water and that basically doubled the energy usage on an otherwise efficent 40C cycle.

And for extratcion, those 5% less moisture mean about 5% less energy usage for drying - not worth that often.

 

[yogitunes]

a few Whirlpool DD machines offered a WARM rinse.....

but in actuality, the deep fill was cold, the spin spray was warm.....not the greatest, but it did take the edge off of a chilled rinse....

problem for some was by the time the hot water reached the machine, the water shut off....

Just saw ......

a commercial for new Cascade DW pods.

 

"Pre-rinsing wastes up to 20 gallons of water, so don't pre-rinse and just use new Cascade!"

The clear glass baking dish they were showing as an example looked like it was still full of food. UGH!

 

Last I checked my DW doesn't have a built-in garbage grinder.

 

BTW, I waste a couple of gallons of water priming the hot water up to the sink so I know I have hot water going into the start of the DW cycle.

 

Next thing they will be encouraging you to hook your DW up to the cold water line instead!

 

[henene4]

...

I dunno, but I never prerinse and almost all DW over here are cold hookup.

Sure, we could run much higher wattage heating elements.

But most run around 1800W top.
You could probably still run 1100-1200W depending on design.
That is a difference but given the difference between washer and dishwasher, cold water hookup for DWs in the US aren't that incredibly improbable to pull off with barely any difference in performance - given they were designed and more so programmed that way.

Actually, for many US DW, pre rinsing by hand seems even less useful.

Sure I would recommend scraping most stuff off.

But from what I understand, many DW run prerinses depending on incoming water temp.
So if it is low, it would just add another short prerinse.
And for that matter depending on the timing water temp might be down significantly again once the main wash happens.

I think with DW the debate is much more differentiated compared to "wash your week long damp stored towels in cold".
