Years ago, my moms neighbour was over for tea. They were in the front sitting room(you know, the room NOBODY is allowed in, except older ladies having tea), and the conversation moved onto cleaning. Anywho, my mom asked the neighbor how she cleans her drapes/shears. The response was, 'oh, I take them down, and soak them in a Borax solution'. Well..... the next time my moms cleaning lady came over, she relayed this information. I guess the cleaning lady thought more was better, and added THE WHOLE BOX. She let them soak for most of the day. When she went to pull them out of the soaking tub, all that was left was long strings, and shreds of fabric..... moral of the story, don't always listen to old wives tales.....
