I rent my house out on Air B and B in the summer.
We had a new carpet fitted and the first bloody guests got a big white stain on the carpet. It is outside the bathroom door so I'm assuming it is shower gel or body lotion.
I have tried carpet cleaner 4 times now and it is still there. The most recent guest has mentioned it and it doesn't look great to be honest.
There must be a way surely? It doesn't look bleached really, but I guess it could be.
