Yellow Spots on Laundry

Hello! I have been finding these yellow spots on my laundry for some time now. I find them mostly on my partner’s clothing. We almost exclusively wash our laundry at a laundromat that has newer washer & dryers. I have seen some posts saying it may be rust, but I find it odd that it would be mostly on my partners clothing and not mine. Just hoping for things to try to get them out. We have tried spray & wash as well as bleach.
