I haven’t tried these yet but did some research when I was looking at buying them, looks like you can re-use, some people tear them in half to get more mileage from them and I’ve checked out the DIY ones which I might try.
I re-use my colour catcher sheets constantly. Slowly but surely they turn grey and when they start to disintegrate that is when I dispose of them. This is a fantastic product and I sing its praises long and loud. Don’t try cheaper versions as you will be wasting your money (voice of experience talking).
Good old google has the answers you seek.
Also apparently you can make your own by soaking a white cloth in washing soda crystals and then drying the cloth.
I wouldn’t think so & I wouldn’t be game to. You risk the colour leeching from catcher onto something else or not being as effective in catching the other colour.
