If you're looking to break the paint seal around an air vent return, it's likely that you're planning to replace the vent or scrape away old paint to repaint. Before you begin, it's important to note that sealing return vents can cause damage to your HVAC system, as it will need to work harder to compensate for the lack of airflow. If you're sealing vents, it's best to seal supply vents, and only seal one or two as sealing too many can cause damage by increasing pressure. If you're set on breaking the paint seal around an air vent return, you can use a utility knife to cut the paint around the vent, then use a putty knife or screwdriver to scrape away the paint. You can also try using fingernail polish remover to deteriorate the paint, and then use a knife or screwdriver to break the paint seal.

What You'll Learn
Use a utility knife to cut around the vent
To break the paint seal around an air vent return, you can use a utility knife to cut around the vent. This method is also useful when removing any painted trim, such as chair rails, and door and window casings.
Firstly, ensure you have a sharp, new blade in your utility knife to achieve a clean cut. Apply just enough pressure to slice through the paint layer first, and then the baseboard will pop free without damaging the wall. Be careful not to cut too far up—try to keep the cut right where the vent meets the wall.
You can also use this technique to carefully scratch away paint from screw slots. Be sure to wear eye goggles as protection from flying paint chips. It may take a few minutes to clear each slot, but it will ensure a snug fit for your screwdriver.
After cutting around the vent with a utility knife, slowly remove the vent cover. Work slowly in case there are spots that the knife didn't cut all the way through, to avoid damaging the drywall behind it.
Once the vent cover is off, you can take a putty knife or a screwdriver to scrape away any remaining paint.

Scrape away paint with a putty knife or screwdriver
Scraping away paint with a putty knife or screwdriver is a common method for removing paint from air vent returns. It is a reliable way to remove paint, though it can be time-consuming and require some effort.
To begin, use a utility knife to cut the paint around the vent. This will help to loosen the grip of the paint. Then, take your putty knife or screwdriver and start scraping away the paint. It is important to be gentle and careful during this process to avoid damaging the surface underneath the paint.
A putty knife is ideal for scraping paint because of its blunt end, which reduces the chance of gouging the surface, and its flexibility, which allows you to get under the paint more easily. When using a putty knife, bend it and gently push until the paint no longer comes up easily.
If you are using a screwdriver, try placing the corner of the blade into the slot and striking it with your palm. This can help chip the paint out of the slot. You can also try using a little paint remover on the screw heads and then scraping the loosened paint with a knife blade.
For stubborn paint, you may need to use a combination of tools. A wire brush can be useful for removing raised, peeling, or blistered paint. Additionally, a heat gun can be used to soften the paint, making it easier to scrape away. Always be cautious when using a heat gun, and avoid burning yourself by aiming the gun away from your body when not in use.

Apply fingernail polish remover to deteriorate paint
To break the paint seal around an air vent return, one method is to apply fingernail polish remover to deteriorate the paint. This method is ideal if you want to avoid creating a mess.
First, use a utility knife to carefully cut around the edges of the vent. Be sure to only cut where the vent meets the wall, and avoid cutting too far up. Once you've loosened the paint with the knife, you can use a putty knife or a screwdriver to scrape away the paint.
Now, apply the fingernail polish remover to the paint surrounding the vent. You can "brush" it on with a Q-tip. To prevent the remover from evaporating too quickly, cover it with plastic wrap and tape the edges with painter's tape. The remover will eat away at the paint, making it easier to remove.
After allowing the remover to sit for a few minutes, you can use a screwdriver or nail driver to tap the screws and loosen the grip of the paint. You may need to use the utility knife to cut the paint out of the screw slots to get the screwdriver in. Once the paint has deteriorated, you can break the screws loose and remove the vent cover.
This method is a simple and effective way to break the paint seal around an air vent return without causing damage to the surrounding wall or surface.

Cut paint from screw slots to insert a screwdriver
To cut paint from screw slots to insert a screwdriver, you can try the following methods:
Using a Knife
Use a utility knife to cut the paint around the screw slots. You can also use a utility knife to chip off the paint from the screw head. This method can be slow and tedious, especially when dealing with multiple screws.
Hammer and Screwdriver
Place a screwdriver in the screw slot and tap it with a hammer. This may help break through the paint or put a dent in the screw head. From there, press down and slowly unscrew the screw.
Hot Air Paint Stripper
Use a hot air paint stripper on a low to medium setting to soften the paint. Once the paint is soft, use a flat-bladed screwdriver to remove the paint from the screw head and slot. Reheat the screw to help loosen it further.
Nail Polish Remover
Apply nail polish remover to the screw head with a Q-tip. Then, use a knife or screwdriver to scrape away the loosened paint.
AWL
Use a cheap awl to dig out the paint from the screw slot in both directions. This method may also be used to clean metal hardware by boiling the awl in a TSP solution afterward.
Dremel
A Dremel with a cutting wheel attachment can be used to cut around the screw slots. Be careful not to make the screwdriver too sharp, or you may crack the screw head. After cutting, tap the screwdriver into the slot with a hammer and turn counter-clockwise to remove the screw.
Flat-Head Screwdriver
Use a flat-head screwdriver to chip out the paint from the screw slot. You can also use the corner of the screwdriver blade to strike the slot with your palm, chipping away the paint.
Wire Wheel Attachment
Use a rotary tool with a small wire wheel attachment to remove paint from the screw slots. Be cautious when using this method, as running the brush at too high a speed can cause steel whiskers to embed in your skin.
Soaking in Hot Water
Soak the screws in hot water and then rub them with a rag to remove the softened paint.
Boiling in TSP Solution
If you are dealing with small pieces of hardware, you can put them in a tea ball and boil them in a TSP solution to remove the paint.
