Giving old air vents new life with special cleaning and refinishing — earlier

This post was originally published back in the infancy of my blog – October 2012! Unfortunately, my DIY photography skills dorsum in 2012 were as well in their infancy, and later on nigh a decade of having this article online, those depression-resolution photos didn't serve this tutorial well.

Luckily, the need for air vent upgrades is a common one, so I recently had another opportunity to repeat this DIY. Because air vents are exposed to almost constantly flowing air, the metal seems to pit, scar, and rust much faster than metals and other parts of our homes. My suspicion is that much similar metals used on boats or outdoors, moving air creates a much harsher environment for metal finishes.

Redoing this DIY

Faithful readers know I left Militarist Hill Business firm in 2015 to relocate to Seattle for graduate school, and later on graduating I returned to Missouri in 2021, this fourth dimension settling in an urban neighborhood in St. Louis in a abode I've affectionately nicknamed "Hawk Hill Cottage" as a throwback to the big farmhouse and acreage of the original Militarist Hill for which this blog is named.

Products linked below accept been researched and tested on this project. Equally an amazon associate, we earn from qualifying purchases.

Settling in St. Louis, I purchased a 110-yr-former cottage that had been lovingly renovated over 15 years by the previous owner. Although much care had been given to a renovation that involved gutting the house to the studs, the air vents were uninspired at best and kind of gross at worst. Y'all can see in these images the registers, air intake, grills, and air vents ranged widely in condition from perfectly okay slow brown metal registers to rusty and corroded grilles.

Presently after moving in, I knew this was the opportunity I was looking for to redo my old tutorial on cleaning and painting, this time with high-quality photos and a simple step-by-step tutorial. Once the pigment was dry out this project was finished and I was THRILLED! A complete makeover for my vents for only the price of 1/8th of a tin can of spray pigment. I used Rustoleum'due south Oil Rubbed Bronze for an upscale accept on a bones spray pigment terminate.

Hither's the original stride-by-step guide, updated for 2022 with new photos, materials, and clearer descriptions.

How to Deep Make clean Air Vents

When y'all live in an sometime business firm, certain things just look former, and with time and busy schedules, ofttimes they don't get cleaned, replaced, or even noticed. The vents in the dorsum section of Hawk Loma fell into this category: rusty, corroded, and I'm afraid to admit what that white cobweb-type stuff might contain. Ane evening I noticed how rough these vents looked and I decided to remedy them.

(Well, That'southward non totally true. Actually, I noticed them, then researched how much information technology would cost to replace all the air vents in my firm, then I decided to attempt to clean them upwards! )

First, Wipe or Rinse off Surface Debris

If there'south a lot of loose debris, rust, or pet hair on/in your air vent, start the vent cleaning process by rinsing off this surface layer, or wiping it down with a damp rag.

Next, Run Through a Dishwasher with Citric Acid

The dishwasher is the fastest style to deep clean air vents, and an boosted tablespoon of citric acid in with the wash volition even tackle rust on your heat grilles and registers.

It's a adept idea Not to wash stuff this gross with regular dishes that you eat from. (Sometimes I only dedicate a dishwasher load to utility items like air vents, dog bowls, tools, flea market-bound recycling-centre drinking glass, and empty planters.) If you lot've read much on my blog, you know that I think Citric Acid fixes just about whatsoever cleaning problem- so toss a tablespoon or two in your dishwasher to get an actress deep clean.

Lastly, Remove Corrosion with a Steel Brush

Later on the vent was clean, I realized how rusty my vents actually were, and that it was the rust that was collecting dust particles which, combined with summer air-conditioning moisture, created more rust and general gunk. If you notice rust on your air vents, scrub off rust and corrosion with a steel brush, (if you are dealing with a lot of rust, check out my no-scrub rust removal remedy ). Rinse thoroughly or run the vents through another dishwasher bike and so let the vents dry completely overnight.

If you don't have a steel brush get one- they are fab! Don't expect in the grill department- grill brushes are marked way upwardly, only simple, cheap steel brushes can be found in the pigment scraping tool section of your hardware shop.

How to Repaint Air Vents with a Metallic Stop Spray Paint

Once your vents are make clean and any rough spots on the surface sanded smooth, it'southward fourth dimension to repaint to really get the WOW-feel of taking vents from grungy to brand new-looking.

2. Select & Purchase Paint

While yous'll find a whole department of this article on tips for what color to paint your heat registers, this decision should exist made before progressing. In these photos, you lot'll see Rustoleum's Universal Metal line: Oil Rubbed Bronze (the 2012 project) and Gunmetal Grey (2021) registers.

2. Ready a Painting Space

Professional results from spraypainting only crave a few small preparations. First, choose a well-ventilated area that is not exposed to wind, and lay downward cardboard or paper to protect nearby surfaces from overspray. Never spraypaint indoors.

Working inside a one-half-broken-down paper-thin box to protect my driveway and comprise over-spray, I began painting my vents.

3. Pigment in Multiple Light Coats

The cardinal to beautifully repainted vents that await like they take a manufacturing plant finish is to not blitz the painting process. The all-time results come when I really shake my spray pigment cans well then pigment my vents with several light coats from many angles.

Paint from many angles. Paint from 1 angle, permit dry, then paint from some other angle, let dry, etc. Lots of very calorie-free coats of paint from many angles help ensure that paint covers every surface that might show when someone walked by, over, or effectually the vent. Light coats help forestall paint from running and pooling in areas that got over-sprayed while I was trying to reach hidden spots.

Advisedly paint the open up/close machinery. Commenters on this post have asked, wisely, virtually how the open/shut mechanism inside a heat vent works after repainting. I've painted nigh a dozen vents using this method- light coats repeated over and over-and never had an issue with polish open/close afterward. The central is preventing heavy overspray from pooling around the mechanism of the closure.

How to choose a paint color for your HVAC vents

At that place are so many types and colors of spray paint on the market place that a project like this – often without an obvious answer to what colour y'all should choose – tin feel overwhelming. Don't worry, I take some tips on how to choose the perfect paint color for repainting rut vents, return air grilles, and antique-style registers.

1. Decide whether to Cull a New Colour or Repaint the Old Ane

Cull whether y'all want to match or change the original color. If you like the colour of your vents but non their damaged end, choose a pigment color that matches the existing colour (the best way to get a match is to take the vent with you to the hardware shop to buy paint.) If y'all find the current color of your oestrus vents to be a bit of an eyesore, bound to the side by side step.

2. Determine on a Color Family

In one case you lot've decided you lot want a different color cease for your heat vents, the job of choosing a pigment color gets real. I recommend evaluating ii things when choosing a stop for your repainted heat vents:

A. Existing metals in your domicile. While metal finishes tin be mixed successfully, many homes have one metal that is repeated consistently throughout the home. If, for example, all your doorknobs and calorie-free fixtures are rubbed oil statuary, so it's a clue rubbed oil bronze paint might piece of work well on your repainted vent- except you still demand to consider B.

B. Before automatically choosing a matching end, consider the floor or wall surrounding each heat vent. If the metallic used in other areas of your abode would create an eyesore if placed in this particular spot, and then information technology is best to choose a pigment color that will blend in, rather than friction match.

For case, on my gray-toned pergo laminate floor, the antique gold used for fixtures in the rest of the business firm would accept awkwardly drawn the eye to estrus vents in the floor. By painting them, instead, with Rustoleum's Gunmetal Greyness, I was able to help my utilitarian heat vents visually blend into the floor.

3. Find a Metallic Spray Paint in the Finish You've Selected

After you've decided what color tone you'll utilize to match, complement, or blend your estrus vents with their surroundings, it's time to choose pigment.

Hands down, the best paint for repainting air vents are colors in Rustoleum's Universal Metallic line. The colors available range from metallic brass, copper, golden, gunmetal gray, rubbed oil bronze, and stainless steel, but as well include flat colors with a lilliputian bit of a metal sheen like apartment soft fe, flat chestnut, and matte grey.

This is an easy projection that only takes about 10 minutes total of hands-on work for each vent- perchance less! A bit more than time is involved in waiting for the vents to dry afterward washing and over again for the pigment to dry. This project can be done in a weekend- perhaps even in a day.

Concluding Thoughts

This post on updating air vents (a.one thousand.a. grills or registers) was one of the showtime posts on hawk-colina.com. I beloved to tell how quick and easy it is to update my registers for nearly no toll. And so when I moved into a cottage in urban St. Louis with gross, icky floor registers, I knew exactly what to do.

And since my picture-taking skills in 2010 are very different than 2022, I decided to record my repeat of this archetype one-time DIY projection. As you can come across, the results were every bit equally dramatic as the first time around. I am confident that when the cottage sells in a few years, the buyers will exist impressed with these modern-looking gunmetal greyness vents and registers.
