Hi oomis 1105! Thanks for all the info. Where would I get Sodium HYPOChlorite? Is that the generic name? Would I have to ask in the chemist? I use the St. Motitz Well Done on whites and colors and all the collars and cuffs and any spots and it is fantastic. Then I wash on 40 degrees C and add the washing liquid to machine with vanish powder. There is a pink tub of Vanish for colors and a white tub for whites. Everything is like the day I bought it! B’H! I wash shirts by themselves, whites and colors seperately and when they are wet, I take them out from the machine, hang them on hangers and while wet spray with Faultless Regular Starch (from Costco), on the collars, cuffs and a quick all around, and leave to dry naturally. Then I iron with a steam iron. When one of my sons, came back from Yeshiva in Eretz he was so used to giving the shirts there to the launderette that he started to do it here. It is very expensive in London, and he stopped. He just gave me a compliment, “that no one does shirts like you, Mom, keep up the great work!”
I even use Well Done on the tablecloths, it is an amazing product and due to the accidents in Eretz and USA with it, they only have it in a few Kosher grocery stores.
And, yes I do lock it up in the garage and no one else has the key! You can soak tablecloths or whites (shirts) in soda cystals that have been dissolved in water to get out stains, in the last resort.
Wishing everyone a gutten erev Shabbos!
