Totally agree about the hair dryer—tried a heat gun once and nearly warped the plastic ring on my old heater. The lower heat from a hair dryer feels a lot safer, especially when you’re not sure how brittle the plastic’s gotten over time.
The vinegar trick is gold. I used to go straight for WD-40, but after seeing what it did to one of my rubber washers (turned it into mush), I switched to vinegar and haven’t looked back. If anyone’s curious, I usually soak a rag in vinegar, wrap it around the stuck valve, and let it sit for an hour or two. Sometimes I’ll tap the valve gently with a wooden spoon to help break things loose—nothing fancy, just enough to jostle the buildup.
One thing I’d add: if you’re dealing with a really stubborn valve, try running some hot water through the tank first (if possible). Seems to help loosen things up before you even start with the vinegar. Not sure if that’s just luck or if there’s some science behind it, but it’s worked for me more than once.
I’ve had mixed results with the hot water trick, honestly. Sometimes it seems to help, other times I feel like I’m just wasting water and time. Maybe it depends on how much mineral buildup you’ve got in there? I do agree with this though:

WD-40 is great for a lot of things, but I learned the hard way that it’s not worth risking the seals or gaskets—especially if you’re trying to avoid extra costs down the line. Vinegar’s cheap, safe, and you can use it for a bunch of other stuff around the house.
Has anyone tried using a silicone-based lubricant after cleaning off the valve? I’ve heard it can help prevent sticking without damaging plastic or rubber, but I’m always wary about introducing anything new that might cause issues later. Curious if that’s overkill or actually worth it in the long run...
Hot water trick is hit or miss for me too—sometimes it’s like magic, other times I’m just standing there with a bucket, wondering what I’m doing with my life. I’ve definitely seen it work better when the buildup isn’t too gnarly, but once you’ve got a full-on mineral fortress in there, it’s basically just a warm bath for your frustration.
Vinegar, though? That stuff’s the MVP. I once tried WD-40 on a sticky valve and ended up with a washer that looked like a chewed-up gummy bear. Lesson learned.
As for silicone lube, I’ve used it a couple times after a deep clean. Here’s what I noticed:
- It keeps things moving smooth for a while, especially on older valves.
- No weird reactions with rubber or plastic (at least not in my experience).
- Just don’t go overboard—too much and it gets messy, plus you don’t want it gumming up the works.
Honestly, it’s probably not necessary every time, but if you’re already in there and have the stuff, it doesn’t hurt. Just my two cents...
“sometimes it’s like magic, other times I’m just standing there with a bucket, wondering what I’m doing with my life.”
That line hits home. Been there, staring at the drain and questioning my choices. You’re spot on about vinegar—it’s saved me more than once, especially when the buildup isn’t too far gone. I’ve also learned the hard way that WD-40 and plumbing don’t mix. It’s tempting to grab whatever’s handy, but sometimes it just makes things worse.
Silicone lube is a good call after a deep clean, but I’d echo your caution—less is more. I’ve seen folks go overboard and end up with a slippery mess that attracts dust and grime. If you’re already in there, sure, but I wouldn’t make it a routine thing.
Honestly, you’re doing everything right by experimenting and learning as you go. Just remember to turn off the power or gas before poking around the heater—safety first. Sometimes these “quick fixes” are more about patience than anything else...

- Can confirm, buckets are now my best friends.
- Tried vinegar—worked, but the smell lingers way too long.
- WD-40? Regret. Learned that one the hard way.
- Not sure about silicone lube. Feels like adding more problems if you’re not careful.
- Turning off the power is key... learned after a tiny zap. Won’t do that again.
