whitest whites
These are all intersting news - but have to be transmitted and modified for their use in Germany as we have different products here..
But let me please give you a hint to what I found out by chance. Once I had some badly stained table-cloths and table-napkins to clean and did so in the washer with all the powders and stuff and they came out bright white and spotlessly clean. Really spotlessly? There were still some stains on them, yellow ones, pale but still to be seen, especially when holding the item against the day-light at the window...
I remembered the way people used to wash in the old days here in Germany and took a big pot out of the kitchen cupboard, filled it with luke warm water, added some washing-soda which I disolved first to soften the water and added grated bar soap. After having disolved the soap I added the napkins.
At least I brought it to the boil on the kitchen stove within half an hour on medium heat, switched to low then and finally let it simmer for another half an hour with the lid ajar, stirring occasionally.
After that time I removed the lid and was totally astonished to see the change of colour of the suds. I had started with an opaque-white foamy wash-water which was now yellow-brownish-grey and the foam had totally disappeared!
I took the napkins out and rinsed them in tap-hot water first, then in warm and finally in cold water until water stayed totally clear. The stains had completely disappeared!
But what on earth had made the suds become so ugly looking? The items seemed to be clean before...
So, I got in mind it could have been a chemical reaction during the boiling process or maybe one with detergent residues in the fabrics.
I did the whole process again without adding any items to the suds. But even after let the suds boil for 3/4 of an hour and finally adding some detergent and letting boil it again for half an hour, the suds didn't change at all. They stayed opaque-white and only the foam had disappeared after having added the wash powder as these contain some additives against overfoaming in German FLs.
So, I came to the clue that all that yellow-grey stuff must have been still in the fabric although it seemed to be clean. Also I think that, if we wouldn't have all these OBAs in all the detergents nowadays, we would actually SEE how badly washed our fabrics are today, compared to those which were soaked, boiled and lawn-bleached and finally re-washed, rinsed and blued in the old days of our (great)grandfathers...
And last not least it should be mentioned that fabrics treated like that, were DEFENITELY GERMS FREE at all - without disinfectants or chlorine bleach or any silver nano technology and stuff!
Happy New Year to all of you!
