Soffit vents are intake vents; they allow cool outside air into the attic. This airflow moves the hot air out of the attic exhaust vents. Soffit vents are not difficult to clean, and keeping them clean is very important for your home's ventilation. You should clean them at least once a year. The best way to clean soffit vents is by using compressed air bursts to blow away the dust and dirt. These tips will show you how to do so.

Set Up the Ladder

Set up a ladder close to the soffit vent, at a safe angle. Make sure someone holds it from below, so you can work safely. Wear gloves, as well, so any kind of sharp objects in the debris cannot hurt you.

Turn On the Compressor

Turn on the air compressor and then hold the end of the hose tightly. Hold it three to four inches away from the soffit vent, so that the bursts of air can clean the dust away. Make sure that when the compressor is on you hold the hose tightly. Do not aim it at anything besides your soffit vents, as it could injure people or break windows. For your own safety, keep the pressure normal to high and avoid placing your hand on top of the hose and wear goggles.

Clean Out the Vent

Now, simply aim and release the compressed air into the soffit vents. The bursts of air will clean and blow away dust, dirt, or debris. Repeat this process once or twice a year to keep your soffit vents in working order.
