Funny, I was just thinking about this last weekend while cleaning up some corroded window latches. I’ve tried lithium grease too, but it seems to attract dust and grit over time—ever notice that? I’m starting to wonder if a silicone-based spray might hold up better, especially since it doesn’t seem to gum up as much. Anyone tried both and noticed a real difference?
I’ve been down that road too—lithium grease seemed like a good idea until I noticed the window tracks getting gritty, almost like sandpaper over time. Switched to silicone spray last winter, and it definitely stayed cleaner, but I wonder if it really protects the metal as well as lithium does? Maybe it’s just my old 60s windows, but I’m curious if anyone’s had issues with silicone breaking down in sunlight or cold weather...
Funny timing—just last month I had to pry open one of my 70s sliders that felt like it was glued shut. I’d used lithium grease years ago, but it definitely turned into a magnet for dust and grit. Silicone spray is cleaner, yeah, but I’ve noticed it gets kind of tacky in the cold. Not sure about UV breakdown, but my tracks are indoors so sunlight’s not a huge deal. Still, I do wonder if silicone really prevents corrosion long-term or just makes things slippery for a while...
Man, sliders from the 70s are their own special breed of stubborn. I had a set in my old apartment that basically refused to budge every winter. Tried WD-40 at first (rookie mistake), but that just made the tracks all gunky and weirdly sticky. Then I went the lithium grease route too—worked for maybe a year, then it was like someone dumped sand in there. Every time I opened the window, it sounded like I was grinding coffee beans.
Tried silicone spray last spring after a buddy swore by it. It’s definitely less messy, but I totally get what you mean about it getting tacky when it’s cold. Mine felt fine in the summer, but once November rolled around, it started feeling like someone poured syrup in the tracks. Didn’t notice any rust, though, so maybe it does something for corrosion? Hard to say. The windows are still inside, no direct sun, so UV isn’t really on my radar either.
I’ve heard some people use graphite powder instead, but honestly, that stuff just gets everywhere and makes a mess. Plus, my cat managed to step in it and left little gray paw prints all over the sill. Not ideal.
Honestly, at this point I just vacuum out the tracks every few months and hit ‘em with a bit of silicone if they start sticking. Not perfect, but at least they open without a crowbar now. Window tech has come a long way... but those old sliders are gonna outlive us all, sticky tracks and all.
Man, I’m right there with you on those old sliders. First winter in my place, I thought maybe I’d just lost all upper body strength trying to get the window open. WD-40 was my go-to for everything, too—until I realized it just created this weird sludge in the tracks. Does anyone actually know what’s in that stuff? Anyway, I’ve tried silicone spray too, but mine still sticks when it gets cold out. Is there some secret trick I’m missing, or is this just a rite of passage for owning an older house?
Yeah, WD-40’s like the duct tape of lubricants—except, yeah, it gets gunky in window tracks. I’ve had better luck with powdered graphite, but it’s messy and honestly doesn’t last long in my drafty old place. Sometimes I wonder if the cold just shrinks everything tight or if my windows are just warped from decades of use. Has anyone tried actually taking the sashes out and cleaning the tracks? I keep thinking about it but never seem to get around to it...
- Totally get the hesitation—pulling sashes sounds like a hassle, but it actually made a big difference for me.
- Did it on two old windows last fall. A bit of elbow grease, but the tracks were full of gunk I never would've reached otherwise.
- Cold definitely makes things tighter, but decades of settling and paint buildup don't help either...
- If you ever get around to it, just watch out for those old sash cords—they can snap when you least expect it.
I get why folks want to pull the sashes and deep-clean, but honestly, I’ve had more trouble than luck with that approach. Last time I tried, the cords snapped and I ended up with a stuck window for weeks. For me, just cleaning what I can reach and hitting the tracks with a silicone spray has kept things moving and the locks working fine. Not saying a full teardown isn’t worth it sometimes, but I’d rather avoid extra repairs if I can help it. Maybe I’m just lazy, but less fuss has worked out better in my old drafty place.
I totally get where you’re coming from—after wrestling with a jammed sash in my place last winter, I’m not eager to pull anything apart again unless it’s really necessary. Here’s my low-effort routine: quick vacuum in the tracks, wipe down the locks and handles, then a spritz of silicone spray on the spots where the window slides. Takes maybe 10 minutes per window and keeps everything moving without drama. The only time I’d go deeper is if something’s actually stuck or squeaking like crazy. Sometimes “good enough” really is good enough, especially in these old houses.
- Totally agree on not over-complicating things unless you have to. I used to go all in—removing sashes, deep-cleaning every nook—but honestly, it never made much difference for the locks.
- My quick version:
- Handheld vac for loose stuff
- Damp cloth (sometimes just an old sock) for the grime
- Little dab of graphite powder if the lock feels stiff (learned the hard way: WD-40 is a dirt magnet over time)
- I do a “test run” after—open/close a few times. If it’s smooth, I call it a win and move on.
- One thing I noticed: if you skip cleaning too long, old paint chips and grit can really wreck the locking mechanism. Had to replace one last year because I got lazy.
- Not sure about everyone else’s houses, but in mine (built ‘47), sometimes “good enough” is as good as it gets... especially when you’d rather be doing literally anything else besides window maintenance.
