Oxyclean ball
Hi all of you!
The "secret" of that ball should be the same as with the "Tabs" here in Germany for the dishwashers. There's a coating arround each layer of detergent that has a special point of temperature to dilute. With the "Tabs" here, the first layer melts in cold or luke-warm water for the pre-rinse. Next layer dilutes only at temperatures higher than 50°C for the cleaning, finally there's a little red ball inside the "Tabs" which only melts at 65°C and which contains the rinsing agent. Unfortunately there are also cycles with 70°C or gentle programmes with only 45°C in which the mechanism doesn't work!!
The Oxyclean-balls, I think though, do not dilute in cold water but in warm or hot water, so the first layer of detergent dilutes in the first wash-water down to a second layer of protection film which melts only in cold water. This protects the next layer of warm-dilutable film underneath from diluting during the first wash. When rinsing takes place, the cold-diluting layer gets washed away but the next hot-diluting layer can't melt in the cold rinse-water. So up to the next wash, nothing happens. And so it goes on layer by layer, until all the detergents have washed away....
That works as long as you do not pre-wash, neither rinse with warm water, nor wash with cold water....
So, I'm asking here: what is it worth for? To me it's a toy for adults!
