One Must Also Remember
Oxygen bleaching depends upon contact time and water temperature. Even with activated perborate bleaches, washing at temps of <110F is gives a much gentler action than say the same product at temps >140. For about ever 10 degrees temperature increases,there is about a 20 percent increase in bleaching action, or thereabouts.
European front loaders have much longer washing times than American top loaders, the main washing machines in the United States, and for which products like Tide with Bleach, CloroxII and most all other oxygen bleaches boosters were designed. Longer contact times equals greater bleaching by simple lenghth of contact time. This is why stains articles are often soaked in oxygen bleach pre-soaks or detergents to shift tough soils and stains. Even with the new "HE" oxygen bleaches, what P&G and others mostly have done is replace high foaming surfactants, with low foaming ones.
If you ever wish to see just how fast and strong oxygen bleaches are as water temperature increases try this experiment:
Place on range one large canning or boiling pot 3/4 full with cold water and add a few tablespoons of oxygen bleach, stir to disslove. Add a few badly stained or discoloured items, and then turn on the range to medium heat to slowly bring the water to a boil. WARNING: Keep an eye on the pot since as the water heats with oxygen bleach will begin to relase oxygen causing foaming and will boil over.
Stirring every now and then watch what happens as the water temperature goes from cold to warm to hot. Once the water starts boiling, turn the flame down to low and allow to "boil" for no longer than 10 minutes. By the end of the process you should have some mucky brown water, but very white textiles.
To remove the laundry from the hot pot, use tongs, a dolly stick or something to lift the hot and wet laundry into another pot or sinkfull of warm water to gradually cool down,rise. Continue rinsing with warm to cool water, or simply wait until the items have cooled enough to touch, and bung into the washer and let it take care of rinsing.
