Cold water washing has arrived

Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

Help Support :

Tested powdered Tide Professional on a purposely stained kitchen towel, this time using cool water. I paused the washer as it began to drain the wash water—it still drained the rest of the water, but I was able to stick an instant read thermometer into the load and it registered 74 degrees F. As it had just completed a 50 minute wash tumble, I assume the water was at least a few degrees higher earlier in that portion of the cycle.

Interestingly, although it may be hard to discern in the photos, Tide Professional was slightly better at removing the very tough stains in warm water—around 100-105 degrees F.

Several other items in the load had smaller, garden variety stains on them: chocolate syrup & Rao’s marinara on a cotton/poly blend shirt; soy sauce, blood, blue shaving cream and Colgate charcoal toothpaste on kitchen and bath linens. All of those stains were completely removed.

FYI: Cold tap water here—having purged the pipes of the warmer “indoor” water—is currently 57 degrees F. Since the cool water test was not an improvement on the warm water test, I’m not going to bother testing Tide Pro in tap cold.

For this latest—and last—test:
Washer: front-loading Speed Queen model 7009; Normal cycle; max soil level (50 minute wash tumble); cool water setting.
Detergent: 60g powdered Tide Professional detergent.
Kitchen towel was stained, then allowed to dry for 12 hours before laundering.

So Jon & Eugene, is the Tide Profssional outperforming the Tide w/Bleach powder, a tie, or the Tide w./Bleach the best? And Eugene you've done so many tests throughout the years.

This is why I can't stand today's washers except Speed Queen Laundry. In addition to forcing cold water washing, they don't fill up completely and the wash action is weak. How else will laundry get clean? This is a big culprit when trying to wash sturdy cottons like t-shirts and jeans.
 
Remarkably, I ordered a box of Tide Professional AND THEN found this thread. It's always nice when the Internets are all thinking the same thing, about the same time.

Rookie question with this: Is there any harm in washing on warm? That is, will I be deactivating or not-optimally-activating whole groups of ingredients by turning up the temps just a bit?

Thanks!
 
For reference, I just found the service manual for my washer - GFW450SSM1WW, and it states the following about temps:

* Cold can be tempered by cycling of hot water valve to achieve target temperature of 70°F (21°C).
* Warm can be tempered by cycling of hot and cold valves to achieve target temperature of 86°F (30°C).
* Hot can be tempered by cycling of cold water valve to achieve target temperature of 110°F (43°C).
* Sanitize can be tempered by cycling of cold water valve, or heater operation, to achieve target temperature of 160°F (71°C).

...which reads like what P&G is looking for is actually what GE calls "warm" anyway. Figures.
 
Yeah, at least knowledge is power here.  

Honestly, though, with both boys now off in college, and only one home for the summer, the overall Cleaning Power Required (so to speak) is generally a lot lower than when they were both here, a lot younger, and we were all camping at least once a month.
 
I’m pretty sure cats feel the same way when they find out you only wash in cold like in reply #109. Cats like to be extra sure there’s no fleas on their blankets and such.
 
I drank the Kool-Aid !!!

Who could resist the Mother General of Aworg? Bought Saturdee on Amazon, it arrived yesterday, and I opened it immediately and started a small load of nasty stuff hampered in the kitchen Visimatic. Pete is right:the smell is intense which was surprising since the Amazon ad said unscented. Puzzling. But I like the scent; it's pretty much Tide with Bleach Powder.

The load of sox and towels and Roxy's kerchief were--as my Aunt Helen would say, "filthy, maggotty dirty," and I threw in some dark colored socks to follow Jon Charles' new commandment to wash cold with darks and whites together. I rinsed the load this morning in my Canadian Beatty for Pete and Paul.

So busy training Roxy, I missed this classic wonderful thread last week, but there she is in the last pic--LEASH FREE.

PIX in a moment. The Proof is in the Pudding.
 
Mickey!!!

I am glad you drank the Kool-Aid.  After all the testing I just ordered my second box.

 

Mother General is so Proud of you! Those washers are lovely and the cleaning seems stupendous LOL ! Who would have thought COLD would ever come CLEAN ???!!

 

Love that Easy Spiralator in the Beatty !!! 

 

Roxy looks like a DOLL! Congratulations, I am now owned by Pegasus - completely!

What a handsome guy! Artey's looking down smiling at you two, and isn't it nice, for us mid-century men, to know that our new best friends might outlive us or check out when we do. Hallelujah !

"Who would have thought cold would ever come clean." What a great quote--one for the books. Bartlett is envious.
 
Thank you Mickey

So you wash in the Kenmore, and have the Beatty standing by for the rinse !! COOL!

 

Oh sorry I mean COLD !

 

Peg, she was born a tripod and you'd never know it ! Fast  fast, they named her Pegleg, which when I rescued her I didn't like, and she got out in the backyard one day and flew around the yard! SO I changed her name to Pegasus the Flying Horse !!!
