LOL Sorry. Is there a question or are you just sharing? Looks like red wine stain that someone tried to clean improperly. If so, perhaps hot water or soda water...
Sorry I did post the message but it’s in the cloud somewhere. 😉 This was after 24 hours in a beach mix.
I wanted to thank those people out there with those life hack savers. Nail varnish remover completely removed it. The guests said it wasn’t them and that there was already a stain there lol.
