I started scuffing the mud lightly with a sanding block after wet-sanding, but then I’m back to chasing dust bunnies.
Man, I know that dance all too well. I’ve tried those cheap tack cloths—honestly, they’re hit or miss. Sometimes they pick up the fine stuff, but other times it feels like I’m just smearing dust around or leaving a weird residue. One time I even had little fibers stuck in the paint. Lately, I just use a barely damp microfiber rag and call it good. Not perfect, but less hassle than chasing every last speck.

I hear you on that. I used to obsess over every bit of dust, but honestly, it drove me nuts. One trick I picked up: after the final sanding, I run a shop vac with a brush attachment over the wall, then follow up with a slightly damp rag like you mentioned. It’s not flawless, but it keeps the dust bunnies at bay and saves my sanity. I’ve found if you try to get it “perfect,” you’ll be there all day... and still find dust in the corners.
Honestly, I get wanting to save time, but I’ve found if you cut corners too much with the dust, it can come back to bite you—especially if you’re painting with anything but flat. I’ve had a couple rentals where I thought “good enough” was fine, then the sunlight hit just right and every little speck showed up. Sometimes it’s worth an extra 10 minutes to avoid touch-ups later... drywall dust has a way of haunting you if you’re not careful.
That sunlight trick is brutal, right? I learned the hard way in my own place—thought I’d done a pretty good job sanding, but then mid-afternoon rolled around and every swirl mark and dust nib was just... there. I started using a damp sponge for the final pass instead of dry sanding. It takes a little longer, but it really cuts down on airborne dust and helps smooth things out without gouging the mud. Plus, you don’t end up with that fine powder coating everything (and I mean everything).
One thing I’m still figuring out: is it better to vacuum between coats or just wipe with a microfiber cloth? Sometimes I feel like vacuuming stirs up more dust than it removes. Either way, I agree—rushing the cleanup just means you’re stuck doing it again later. And if you’re using low-VOC paints, they seem to highlight imperfections even more for some reason... anyone else notice that?
That sunlight really is unforgiving—nothing like thinking you’ve nailed it, then the afternoon glare shows every last flaw. I’ve been there more times than I care to admit. The damp sponge trick is a game-changer, especially in older houses where dust just finds its way into every nook and cranny.
On the vacuum vs. microfiber debate, I lean toward microfiber for most jobs. Unless you’ve got a HEPA-filtered shop vac, vacuums can kick up fine particles that settle right back down. Microfiber seems to grab more and doesn’t stir things up as much. Sometimes I’ll do a quick, gentle vacuum if there’s a ton of debris, but always follow with a wipe-down.
And you’re spot on about low-VOC paints. They seem to have less “body” or something, so every little imperfection stands out. I’ve started using a bright work light at a low angle while sanding and between coats—it’s not fun, but it saves me from surprises later. It’s tedious, but that extra bit of prep pays off when the wall actually looks smooth in daylight.
