How to remove this brown stain from my shower tray

Hi,

Can anyone recommend how to remove the brown stain from my shower tray in the attached picture?

I have tried bleach&lots of scrubbing as well as salt and lemon juice, both with no visible effect.

Thanks

Would help to know what caused it ? Acrylic bath cleaner should polish it out .

Thanks - will try that. Stain was already there when I purchased the house so cause is unknown.

If it's a burn mark, you can't remove it. For anything else, cream cleaner should work. Stronger would be a polishing compound.

Have you tried bartenders friend? Whilst I haven't used it on the shower, it is amazing for removing difficult marks and stains.

Will try the creamer that foxhole suggested - just wanted to start with something cheaper first.
