The Cora Ball is a microfiber catching laundry ball.Here is almost everything you need to know to begin washing with your Cora Ball: 1. It's easy: toss, or put, your CORA BALL in your washing machine. The Cora Ball is safe to use in any washing machine, front loader, top loaders (with or without a center spindle), a hybrid, or whatever you have that washes your clothes. 2. READ THIS, your lace will thank you. The Cora Ball works best with your everyday clothes. Please separate your delicates, knits, fine fabrics, anything with tassels, fraying threads or spaghetti straps. There is a chance that these clothes, fabrics, threads or straps work their way into the stalks and wrap, pull or worse. Just keep your Cora Ball on the shelf when you wash these fabrics and delicate garments. If something, like a thin strap, does wrap in your stalks, carefully unwrap. Unless it was made of lace or extremely delicate fabric or had fraying threads, it will be fine. 3. Clean your CORA BALL. Cleaning is easy and similar to cleaning a hairbrush. When you see fuzz/lint balls that are big enough to grab, simply pull them out and throw them in the trash bin (we are working on finding a way to upcycle or recycle them, until then just do the same thing with this lint that you do with your dryer lint). Frequency: it will take some time, weeks even, for you to see the fuzz / lint (see below for what to expect). We recommend having a look every bunch of washes and when you see a big fuzz/lint ball, take it out. Don't worry about cleaning the whole Cora Ball. Those little tangles of hair and fiber will attract more hair and fiber and grow big enough for you to grab easily. 4. Know your fuzz / lint quotient and how much you are likely to collect. There are a multitude of factors that determine both how many microfibers your clothes produce and how much of that fuzz/lint your Cora Ball is likely to collect. They range from the type of washing machine and soap you use, to the settings, water temperature and even the hard or softness of your water.For more, The Cora Ball FAQ
