Stained toilet seat
I have an account that is a small office with a shared bathroom with another office. In the women's restroom, on the under side of the toilet seat are stains that I cannot get out. They appear to have been made by blood. I can get them quite a bit lighter but when I go back in the next day, they are back.
I have tried peroxide, bleach, toilet bowl cleaner, simple green.
Does anyone have any other ideas as to what I can try on this seat?
Thank you in advance for any advice you have.
