I accidentally washed a white bra with a load of red jumpers the other day. I put a colour catcher in out of habit. The bra came out white but with some purple blotches on, which I thought was a little odd as I thought it would all go pink, but whatever. Today I washed a different bra with an old purple and white top (so the purple shouldn't run). Bra came out with purple blotches on it again. Same shade of purple as the other bra, despite being in with different colours. The colour catcher sheets I used are this exact shade of purple, so I'm thinking it must be the colour catchers have done it? Has anyone else had this? And why are the sheets purple now when they used to be white? I don't really care about the bras but I'm glad it didn't happen to any of my other clothes!
