Not sure if it’s overkill, but it seems to help.
Mineral oil’s clever, but I’m a bit wary about pouring anything down the drain that isn’t water. Here’s my take:
- Try just running a splash of water every couple weeks. No chemicals, no oil, just old-fashioned H2O.
- If you’re worried about forgetting (I always do), stick a post-it on the washer or something.
- “Rotten eggs” is bad, but “mineral oil soup” isn’t exactly eco-chic either.
I get the appeal, but sometimes simple’s best.

I hear you on the eco concerns. Honestly, water’s usually enough to keep those traps from drying out, unless you’ve got a spot that never gets used. I’ve seen folks go overboard with all kinds of stuff—sometimes it just makes a mess. If it’s a drain that sits for months, maybe a splash of oil helps, but for most people, just running water every so often does the trick.
Yeah, I get where you’re coming from. I’ve tried the mineral oil thing before, but honestly, just running the tap every couple weeks has worked fine for me. Less mess, less cost. If it’s a drain that never gets used, maybe a little oil makes sense, but for most spots, water’s cheap and easy. No need to overthink it.
- Had a similar issue last winter with that sulfur smell creeping up in the basement.
- I get the appeal of just running water, but I learned the hard way that sometimes it’s not enough—especially if you’re dealing with a floor drain that basically never sees use.
- Tried just topping it off with water every few weeks, but after a long trip, came home to the full-on rotten egg stench. Turns out, the water in the trap had evaporated faster than I thought.
- Tossed in some mineral oil after that (just a couple tablespoons), and honestly, it kept the trap from drying out for months. No more stink.
- Not saying you need to do this for every drain, but if you’ve got one that’s basically decorative at this point, the oil trick is a solid backup.
- Quick heads up: if you’ve got kids or pets, keep the oil bottle out of reach. I had a minor panic when my dog got curious—luckily, crisis averted.
- Also, double-check for any leaks around the trap or pipe joints. Sometimes the smell isn’t just from a dry trap but a tiny crack somewhere. Learned that after chasing phantom odors for a week...
- Agree, though—no need to overthink it unless the smell keeps coming back. Then it’s probably worth digging a little deeper.
- One last thing: if you’re in an older house, sometimes the venting is weird and can siphon water out of the traps faster than you’d expect. Happened in my place after a big rainstorm. Just something to watch for.
Not trying to make it sound more complicated than it is, but after dealing with a few surprise "sewer perfume" moments, I’m all about playing it safe.
Mineral oil in the trap is a game changer, honestly. I used to just pour water down every couple weeks too, but it never lasted. One thing I’d add—if you’ve got a sump pump nearby, sometimes those can dry out traps faster than you’d think. Learned that after a tenant called about “mystery odors”... turned out the pump was pulling air through the floor drain. Never would’ve guessed.
