The kitchen sink in our home has recently been producing an odd aroma - depending on the day, it's a mix of boiled eggs, sulphur, brackish water, or old food.
What we have tried
- garbage disposal cleaner
- regular dish soap
After any of our attempts so far, the smell returns within 1-2 days - even with no dirty dishes anywhere to be seen.
What we can't do* (it's a rental home)
- replace the sink
- major plumbing
What can we do to address this issue?
* if it requires anything "major", it will need a maintenance request, but we're hoping to avoid that and find something simpler
