How do you usually fix stuck or squeaky window locks?

- You’re spot-on—trial and error is pretty much the name of the game with these fixes.
- Silicone spray is efficient, just gotta watch that overspray like you said. Masking tape’s a lifesaver for that.
- I’ve also ended up with graphite stains... not worth it unless you’re desperate.
- Candle wax never did much for me either, but hey, if it makes the place smell better, not a total loss.
- Small tweaks can add up to smoother windows and maybe even a bit more energy saved. Keep at it—it’s worth the effort.

- Agree on the masking tape—saved me from cleaning up more than a few times.

“Candle wax never did much for me either, but hey, if it makes the place smell better, not a total loss.”

- Masking tape is definitely underrated for quick paint jobs or when you’re dealing with old hardware. Saves a ton of cleanup, especially with flaky window frames.
- Candle wax—yeah, I’ve seen it suggested, but it’s never held up for me either. Once the temps climb, it just gums up or leaves streaks. Smells decent, but that’s about it.
- WD-40 is a classic go-to in a pinch, but you’re right—it’s a dust magnet and doesn’t last long if there’s any moisture around. I’ve had to go back and reapply after just a couple months.
- Dry PTFE spray actually works better than most wet lubes in my experience. Doesn’t attract as much grime and seems to handle humidity without turning sticky. I used it on some old double-hungs last year and they’re still sliding pretty well, even after a wet spring.
- If you’ve got swelling sashes, sometimes a light sanding on the contact points before applying PTFE can help too. Not always practical if you’re renting, but worth it if you’re doing a bigger fix.

Humidity just seems to find its way in no matter what… but PTFE has been the least fussy so far for me.

PTFE’s definitely the MVP for me too, especially with old wood windows that swell up every time it rains. WD-40 just made mine sticky after a while—felt like I was attracting every dust bunny in the house. Never had much luck with candle wax either… just made things smell weird. Sanding’s great if you can swing it, but I’ll admit I get lazy and just hit it with the spray most days.

I’ve wrestled with sticky wood windows for years—our house was built in the 50s, and those sashes seem to have a mind of their own once the humidity kicks in. PTFE spray is decent, but I’ve got mixed feelings about it. It’s quick, sure, but sometimes it leaves a weird film that makes me wonder if I’m just masking a bigger issue.

Here’s what’s worked for me (when I’m not in a rush):
1. I’ll pop the window lock off if I can—sometimes you just need a screwdriver and some patience.
2. Then I use a little denatured alcohol on a rag to clean all the gunk out of the moving parts and tracks. You’d be surprised how much old paint and dust gets wedged in there over the decades.
3. After that, I’ll sand down any rough spots on the wood—just enough to smooth things out, not so much that I’m making a mess or causing more gaps.
4. Only then do I hit it with a dry lube (usually graphite powder or silicone spray). PTFE does work, but honestly, it seems to attract less grime than WD-40, which always left things feeling tacky for me too.

Candle wax never did much for my windows either... plus, like you said, it made the room smell like someone left a birthday cake out in July.

The one thing I’d add—sometimes if the swelling is bad enough, no amount of lube will help until you deal with the moisture issue. I ended up running a dehumidifier near my worst windows during storms, which actually made a difference.

Short version: clean first, sand if needed, then lube—but don’t expect miracles if your windows are really swollen up from rain. Sometimes you just have to wait for things to dry out before anything slides again.

I hear you on the PTFE spray—sometimes it’s more of a band-aid than a real fix. I’ve had better luck with graphite too, but it’s messy if you’re not careful. The sanding step is key, especially with 60+ year old windows like ours. Ever tried using a small wire brush instead of sandpaper for the really stubborn spots? I found it gets into the corners a bit better, but I’m not sure if it’s too harsh on the wood long-term.

Ever tried using a small wire brush instead of sandpaper for the really stubborn spots? I found it gets into the corners a bit better, but I’m not sure if it’s too harsh on the wood long-term.

I’ve used a brass wire brush for some of those tough, paint-encrusted corners—definitely gets deeper than sandpaper, but you’re right, it can start to abrade the softer grain if you’re not gentle. I usually follow up with a finer grit paper just to smooth things out. Have you ever tried using a nylon abrasive pad instead? I’ve found they’re less aggressive but still decent at clearing out old buildup. Curious if anyone’s compared the longevity of wood after different methods—does one really cause more wear over the years?

Yeah, I’ve run into the same issue with wire brushes. They’re great for those corners where old paint just won’t let go, but if you press too hard or go over the same spot a bunch, you can definitely end up with grooves in softer woods. I’ve tried nylon pads too—those green Scotch-Brite types—and they’re not bad for lighter buildup, but sometimes they just don’t cut it when there’s years of gunk.

One thing I’ve noticed: after using a wire brush on pine sashes, the finish never looks quite as smooth, even after sanding. Oak or harder woods seem to handle it better. Not sure about long-term damage, but I’d guess repeated heavy brushing could start to wear down the finer details or molding edges over time.

For stuck window locks specifically, I usually try to minimize any harsh scrubbing near moving parts. A little mineral spirits and a toothbrush has worked for me before—less risk of chewing up the wood or hardware. Anyone else ever have issues with brass bristles leaving marks? That’s happened to me once or twice on painted surfaces.

I’ve definitely had brass bristles leave those faint gold streaks on painted trim—always seems to happen when I’m in a rush. Sometimes I’ll reach for a plastic scraper if the buildup isn’t too stubborn, just to avoid messing up the surface. Has anyone tried using those old-school pumice blocks on window hardware? I’ve only used them on tile but wondered if they’re gentle enough for softer woods or if that’s asking for trouble...

- Been there with the brass bristle streaks. I swear, every time I think “just a quick scrub,” I end up repainting trim later.
- Plastic scrapers are my go-to too—less drama, less regret.
- As for pumice blocks, I’ve only used them on tile and one gnarly bathtub ring. Never tried them on wood or hardware. My gut says they’d chew up softer woods pretty quick, but maybe someone’s braver than me.
- For stuck window locks, I usually hit ‘em with a little graphite powder or silicone spray. WD-40 works in a pinch but seems to attract dust after a while.
- Had a neighbor who tried steel wool on his painted sashes—looked like his cat got into a fight with the window. Wouldn’t recommend unless you’re going for “distressed chic.”
- Honestly, sometimes patience and a plastic putty knife are the real MVPs. If it’s really caked on, I’ll soften things up with a hair dryer first to avoid gouging anything.

Don’t beat yourself up about the streaks—it happens to all of us who try to get stuff done before dinner.
