Smelly soil

[DrFoxtrot]

Hello, I'm not sure if this is the right topic for this!

There was a very stinky patch of soil in DP's garden that I think has resulted from anaerobic bacteria, the smell was like rotting teeth/ very bad breath . My main problem is that the stink is on one of my trainers soles and I can't get it out despite the sole looking physically clean. I've tried white vinegar and washing several times in the washing machine.

I've chosen the gardening topic as I thought some gardeners may have had a similar problem. Any tips for getting rid of the awful smell?

Bicarbonate of soda is recommended for fridge smells. Try putting the trainer in a bag with bicarbonate?

My Little Friend pet cage disinfectant spray. I use it in our food waste bin and it seems to be able to get rid of any smell that has permeated into the plastic.

Thank you! I'll give the suggestions a go
