oxy clean and the bleaching effect

[bpetersxx]

boy I am stupid

I washed my black jeans I wear to work in the Calypso

Hot water oxy and detergent

It washed almost all the color out

well i will not do that again

especially on my new black jeans I got for work

One reason Henkel and other detergent makers in Europe had to come up with "color" products as because oxygen bleaching systems in normal products faded colors. More so with repeated or frequent use.

While sodium perborate is more forgiving than sodium percarbonate (the cold water oxygen bleach), both can cause fading.

Detergents for colors and or "darks" usually contain one or more substances meant to counteract chlorine found in municipal tap water. Ironically one substance commonly used is small amounts of oxygen bleach.

Dark colors like that should not exceed 85-90F and use no oxygen or chlorine bleach. Detergent only.

Liquid abd powder oxygen bleach

Actually liquid oxygen bleach here is recommended for colours (it's called "delicate bleach"): it is just hydrogen peroxide.

The problem with powder oxygen bleach (sodium percarbonate) is that when it dissolves in water it produces oxygen (and here we are fine) but also washing soda (sodium carbonate) which is not colour-friendly at all

All of my dark regularly go beyond 90°F, They normally get washed at 140°F, The only thing that I’ve really had happen what a bunch of bleach and rust looking stains from when I washed my laundry in dads washing machine even though we don’t use bleach, all that was used was regular detergent and fabric softener

(I’ll post some photos if I can find the stains)

Reply #3 makes perfect sense. Washing soda instructions usually discourage use for colored laundry.

But then again it all boils down to the quality of dye we`re talking about.
Some dyes hold up amazingly well even to boilwashing, bleaching, high pH and UV ray exposure while others fade quickly even in gentle cold washes with a mild detergent.

I often find it difficult to predict how a garment will turn out quality wise, but try to avoid "wash separately in cold water" items whenever possible.

USA long has had liquid hydrogen peroxide bleach often touted as "color safe" or "for colors".

Being as that may any oxygen bleach liquid or powder can cause fading if dye used is susceptible. Proof of this is one can soak items using a solution of liquid hydrogen peroxide (3% found at chemists of store bought brand of liquid oxygen bleach) to remove all sorts of dye stains from red wine to dye transfer.

When activated oxygen bleaching systems first were developed and hit market back in 1970's or so there soon was a chorus of complaints from consumers. Persons claimed the detergent or other product containing AOB faded dyes or otherwise caused harm to colors. Makers of said products, washing machines and textiles all engaged in finger pointing including toward consumers who were "uneducated". However studies were done to get at bottom of things.

Extensive research showed that oxygen bleach or AOB systems did affect certain dyes more than others. Upshot to this was many textile or garment makers switched to dyes known to be more stable to oxygen bleaching. This and or better labeling was given out telling consumer if things could be bleached, could be bleached with non-chlorine bleach, or simply "NO BLEACH" across board, period.

Detergent makers for their part came out with products for "colors" that either contained no oxygen bleach, less aggressive AOB systems, or no AOB at all.

Problem with AOB systems is they often are too good at their job; many can and will remove marks in warm, cool or cold water. No surprises since whole point of AOB systems was to enable (or get) consumers to "turn down the dial" temperature wise. Persil, Ariel and rest gave same results as with boil wash but at temps of warm or cold water. Problems solved. Well not exactly for items that are coloured or darks.

Well Pete

There’s been lots of decisions here over the years as to how effective Oxy Clean is for bleaching..especially since it does not contain a AOB.
But between the sodium percarbonate and sodium carbonate contained therein..and along with hot water?
Guess the black dye didn’t stand a chance.
Next pair of black jeans.. launder turned inside out in cool water with a mild liquid neutral detergent with no optical brighteners, and hang dry. (Shady spot)
That’s about the best you can do to control fading.

Alkalinity will increase power of hydrogen peroxide or oxygen bleaches based upon same (sodium perborate and percarbonate).

Professional launderers or dry cleaners will kick up power of spotting with hydrogen peroxide by adding bit of ammonia which has a base pH.

In theory sodium percarbonate doesn't need addition of sodium carbonate because it brings its own to party. However cutting sodium percarbonate with washing soda allows less of the former (which is more expensive) but can give same performance. Borax being a weaker base does benefit from sodium carbonate, sodium metasilicate or other alkaline substances.

In UK and other parts of Europe laundries until rather recently removed blood and other soils by washing in soap, sodium perborate and sodium metasilicate. Famous PerSIL is soap, sodium perborate and silicate...

Thing all oxygen bleaches have going for them is one can control things via temperature. For each ten degrees F increase in temp oxygen bleaches will about double in power. This is where "color safe" comes in...

Going back to days of Snowy and other oxygen bleaches that were sodium perborate or liquid hydrogen peroxide people obviously weren't going to be washing colors in hot or very (as in boil wash) temps. Sodium perborate requires temps at or > 140F to really get going, ditto basically for liquid hydrogen peroxide. Thus washing in warm or even cool water using said oxygen bleaches in theory shouldn't harm colors.

As noted above then came AOB systems which changed everything...

Sodium percarbonate on it's own is known as "cold water" oxygen bleach. Owing to its washing soda content it SPC is bit more powerful than sodium perborate thus will work at lower temps.

Yes during my time in Pro Laundry and Dry Cleaning Aqua Ammonia was used for the reasons Laundress has mentioned above.
Sodium Perborate was used mainly at the spotting board so spot could be slowly heated with steam then flushed away and air gun used to dry..provided fabric could take the treatment)
For white loads of laundry (not dry cleaning) professional powdered detergent with ABS was used along with a sour for final rinse.
If you decide to look for neutral liquid detergent for your darks..they’re a little harder to get.
You won’t necessarily find on supermarket shelves
All Free n Clear (military) you may have to order online
Seventh Generation free n Clear
Bio Kleen
Woolite for Darks.
Laundress may have a more comprehensive list or further recommendations if you choose to go that route for your darks (blacks & reds)

The Swiss consumer magazine K-Tipp tested black underwear for men by washing them 30 times at 60 °C (140 °F) using an oxygen bleach containing "Universal" powder.

According to their professor for microbiology and hygiene the high temperature and bleach are necessary to kill germs in those textiles.
No surprise only 3 out of 16 undies tested held up well.
Personally I wouldn`t use a Universal powder for my black undies because of excessive fading from the bleach plus the damage the the high pH of a powder would do to the spandex fibers.
So I wash my black undies even higher than the 60° their care tag suggests but I only use a liquid detergent to keep them in good shape and to protect the color.
My favorite brand of underwear last me at least three years so I think I don`t do anything terribly wrong.
The bottom line is you can`t have it all. It`s either clothes that look like new for the longest time or really clean clothes.

You have to pay for the whole article, the German Consumer magazine briefly reported about this test too and with Google translate you get the idea.

It is really difficult to shift many marks or soils without using some sort of oxygen bleach.

 

[qsd-dan]

One can use ammonia and skip the bleaches, even on dark colored fabrics. Ammonia is caustic and corrosive to certain metals, so keep that in mind.

 

Ammonia can be used in small amounts on septic since it doesn't affect the bacteria, but use it sparingly under those circumstances. Let 'er rip if you're on city sewer.

 

[launderess]

Ammonia is merely a gas (ammonium hydroxide) suspended in water. If left out long enough said gas quickly liberates itself back into air. That is what gives the tell tale ammonia whiff.

Good part of ammonia used in laundry say in washing machines will thus liberate itself into air (again that whiff). This is why vintage manuals on laundry never really suggested using ammonia as an alkaline source for soaking washing. Spot removal was another matter.

By time waste water from washing machine drains into sewer or septic system much of ammonia should have liberated itself. What remains will further reduce due to natural ventilation systems built into all waste water/septic systems.

Far more ammonia comes out of humans (via urine) than ever is used for wash day.

Urine odor Causes

Urine that smells odd might point to an underlying disease or condition.

Yes there is still that toxic "Hygienespüler" if everything else cannot be done, but Kudos to the Swiss for ignoring the care tags from the globalists like Calvin Klein or Hilfiger who think they can turn s**t into gold and get away with it.

They use common sense and traditional laundry methods instead and demand quality clothes for their hard earned Franken which a cheap local store own brand among others apparently deliver.

"Waschtag beim Haushalts-Check! Wer heute Waschmittel kaufen will, wird mit Neuheiten erschlagen. Im Drogerie- oder Supermarkt finden sich Streifen, Tücher, Blätter und vieles mehr. Was können sie? Das checkt Yvonne Willicks mit einer Haushalts-Check-Testfamilie.

Im Schnitt verbraucht jeder von uns acht Kilogramm Waschmittel jährlich. Ein großer Markt also – Hersteller und Handel erweitern die Produktvielfalt stetig. Doch mit der Wahl wächst für die Verbraucher:innen auch die Qual. Brauchen wir das alles? Was kosten die "coolen" Produkte? Wie gut sind sie für die Umwelt?
Wasch-Tabs, Wasch-Pods und Waschblätter – Innovationen, die das Waschen vereinfachen sollen. Wie gut sich die neuen Waschmittel in der Trommel schlagen, testet eine fünfköpfige Familie im Alltag für Yvonne Willicks. Im Labor lässt sie außerdem testen, wie effektiv sich Flecken mit Pods, Tabs und Co. entfernen lassen.
Waren es früher meist 65- oder 90-Grad-Wäschen, versprechen die Hersteller heute saubere und bakterienfreie Ergebnisse bereits bei 20 Grad. Geht das überhaupt? Gemeinsam mit Mikrobiologe Prof. Dr. Dirk Bockmühl klärt Hauswirtschaftsmeisterin Yvonne Willicks, wann man Wäsche auch mal kalt waschen darf und wann es richtig heiß werden muss.

Washing day at the household check! Anyone who wants to buy detergent today will be overwhelmed with new products. You can find strips, cloths, leaves and much more in the drugstore or supermarket. What can you? Yvonne Willicks checks this with a household check test family.

On average, each of us uses eight kilograms of detergent per year. So it's a big market - manufacturers and retailers are constantly expanding the product variety. But as the choice increases, so does the agony for consumers.

Do we need all of this? How much do the “cool” products cost? How good are they for the environment?

Washing tabs, washing pods and washing sheets – innovations designed to make washing easier. A family of five tests how well the new detergents perform in the drum in everyday life for Yvonne Willicks. She also tests in the laboratory how effectively stains can be removed with pods, tabs, etc.

In the past, washing was usually done at 65 or 90 degrees, but today manufacturers promise clean and bacteria-free results at just 20 degrees. Is that possible? Together with microbiologist Prof. Dr. Dirk Bockmühl explains to housekeeper Yvonne Willicks when you can wash laundry in cold water and when it has to be really hot.

Cannot find link atm, but some time ago German consumer testing group stated detergents for "blacks" or "darks" just weren't necessary. A good "colour" detergent was all one required.

That commercial is hilarious, isn`t it? Try to air something like this in the US and wait for excited reactions of various religious and "family" groups. LOL
