Clothes wash still smell pee

[Rumham]

My laundry is being done in the same machine (not at the same time) that washes my kids pee blankets and clothes and even doing a rinse wash between I still smell the pee smell in my clothes when I’m getting hot and sweaty. How can you stop this? Any advise… my mom has tried everything and it just keeps happening. And it’s not like they have pee clothes in there all the time it’s maybe six to eight loads a month and the machine makes all else with a hint of pee
