What is this?

[Brunolarge]

my sons room smells like gone off fish and this stain was under his bed
any idea what this could be? And how best to clean and get rid of the smell please 🙏🏻

Sorry forgot to add pics

Ask him what he thinks it might be? Is the fish smell definitely coming from that stain?

You can use enzyme cleaner like the ones to clean animal piss, shit and vomit. But you need as much info as possible as to the source of it.

Assuming son isn't physically disabled, he should be at least helping you clean.

He doesn’t have any clue what is it or how it has happened

I could cry 😭

Do you have pets? I immediately wondered if it was pet vomit / poo or god forbid they brought in a dead mouse or bird.

No idea but bicarb of soda is excellent for smells. Sprinkle it over the stain, leave for a while then hoover up.

Thank you ☺️

Dead mice smell like fish 🫤

Tomorrow my mum and brother are gong to come up and help me move everything out and deep clean the underneath of his bed. I hope it isn’t a dead mouse 🤦‍♀️😭

What age is your son? Could he help move everything?

Electrics can smell like fish, always good to check sockets and things with any fish smell.

This!

I was just about to write this! Happened to my parents a few years ago in their bedroom. It took them weeks but eventually they found out it was when the bedside lamp was switched on. It was the bulb.

Hope you find out what it is and get it sorted.
