I think you can only use them twice then get new ones.

I believe they can be used again, but not sure how many times.

They can be used again. I re use mine, they go a bit grey,must work ok. When they start to disintegrate, I get rid of them

They can be used again.

You can but they don’t work as well

I reuse it for a couple of times before I chuck it.

I did – several times and without a problem

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).

I reuse mine for a couple of washes. I put it folded in the drawer where the powder goes in

Thanks everyone for your help. Oh make your own ?? I like the sound of that !!

Would be worth trying but only on something that doesn’t matter if you get colour run

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 have actually used it twice by accident and my clothes were fine

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.

If you reuse them you won’t get the same result as before

Sorry but I don’t know what a colour catcher sheet is so not sure if you can use it again ;/
