Peroxide in washing machine?

Posted by beanwabr (My Page) on

I remember reading something a while back about using peroxide rather than Clorox in the wash to whiten your white clothing...that its safer than bleach as well as cheaper...just use in the bleach dispenser as you normally would have done with bleach. Anyone heard of this, or do this?

I've heard of this. I don't think it would be a problem as long as it's WHITES only. I've heard that peroxide also kills mildew. There is even a recipe for daily shower cleaner I found on the web. Mix 1 part rubbing alcohol to 1 part peroxide, a couple of drops of plain dish liquid and a teaspoon of jet dry or rinse aid and a drop of essential oil for scent if you wish.

Several of the "green" liquid oxygen bleaches are mainly hydrogen peroxide. Not sure of the % strength and if they are any weaker or stronger than the inexpensive brown bottles you can get at the drug store.

I've seen it talked about and I think I did use it once or twice many many years ago but I quit using it because it wasn't cheap and guess bleach did fine when I needed it. Around here, peroxide is far more expensive than bleach.

On another forum someone used the Oxy laundry spray in and around her tub. She said everything including grout got clean. She couldn't achieve that using bleach.

Hydrogen peroxide isn't only in the "green" bleaches. It's also in Clorox 2.

It's the active ingredient in VIVID all color "bleach".

Hydrogen peroxide is "oxygen" bleach. I wasn't very good at chemistry, but here goes. Liquid all fabric bleaches generally contain peroxide as the active ingredient, often diluted with other surfactancts, sodium citrate, enzymes or plain water. Powdered bleaches have the ions attached to either washing soda or borax, to become sodium percarbonate or sodium perborate and are often mixed with other surfactants, sodium carbonate, enzymes and brighteners.

A friend of mine runs a commercial laundry that washes linen for a number of large hotels. He mentioned once that one of the chemicals they use in the very large front loaders there is hydrogen peroxide. He said it was because it does a much better job of removing stains and making stuff white compared to chlorine bleach.

Well my next load of whites is gonna get peroxide in the bleach dispenser instead of bleach. I'm curious to try it. I have white wash clothes that are stained from using body wash. I wonder if that small amount will be enough since we're talking peroxide and not bleach.

"Well my next load of whites is gonna get peroxide in the bleach dispenser instead of bleach."

chlorine bleach dispense from bleach dispenser at First rinse...

hydrogen peroxide or sodium percarbonate or sodium perborate are mixed with Other detergent ingredients in Main wash dispenser....

Because oxygen bleach will NOT work on cold rinse water....

Thanks :) That's good to know!

How much peroxide shall I use in a FL washer at the start of the cycle?

Quoting from the link below: "Water temperature affects the bleaching rate of oxygen bleaches. Hot water accelerates the bleaching action. As water temperature decreases below 130 degrees F, exposure time must be increased substantially." So the chlorine bleach dispenser indeed isn't the right place for peroxide, whether your machine dispenses it near the end of the wash, or during the first rinse.

The link also makes it clear that non-chlorine bleaches either contain hydrogen peroxide (liquid bleaches) or form it when added to water (powdered bleaches). So this tip about peroxide really doesn't seem to be such a great discovery :-)

The mention of 130degF contradicts the propaganda that hot washing isn't necessary anymore. This is the official web site of the detergent manufacturers' trade association, after all. What's more, go to the list of page numbers at the top, and click on "7". This page actually defines hot as "130 degrees F (54.4 degrees C) or above. White and colorfast fabrics, heavily soiled loads and diapers." Anyone care to contact the washer manufacturers, and see what they say about this? :-)

That is true. In the hotel case that I mentioned above, they are required to wash linen and towels at something like 185 degrees to meet health dept. requirements. Hot enough to activate the hydrogen peroxide I guess.

FYI... Wal-Mart (of all places) has a house brand "Free" liquid bleach (in a pretty pink plastic label wrapper) that is peroxide. No dyes, colors or enzymes.

Haven't been able to determine what the actual concentration is but it works well for me in my FL. I add a 1/2 to whole cup through the main detergent shoot once the load gets started.
