Shower tray needs brightening up!

[MrsBean21]

Shower tray is dull. Any suggestions what I can use to brighten it up again?
I’m thinking white vinegar, but if you know of something that will definitely work with m all ears! Plan of sprucing up the tray tomorrow.

thanks for reading

Is it plastic? Is it white? This is what I have in the caravan. I bought pink stuff bathroom foam and sprayed it on and left it for several hours. Shower tray was completely different colour afterward I wish I'd done a before pic! Scrubbing did nothing - only spraying and leaving.
In my plastic bath HG mould spray will do similar.

@pastypirate thank you! Yes it’s white and plastic. I will look and see what I can but to spray and leave on.

Barkeepers friend but make sure its the powder
amazing stuff

Thank you @whatsthestory123
