You can brush away the debris causing the soffit ventilation blockage with a long-bristled brush. You only need to push the brush into the vent while moving it up and down (like you would while removing cobwebs).
All you'll really need is a soft bristle brush. If the soffits and fascia are extra dirty, you can wash it with a soft bristle brush and replace the clear water with a solution of water and normal household detergent. This removes any and all pollutants without damaging the surface.
8" x 16" soffit vents provide 65 square inches of net free area for intake ventilation. That much area needs to be clear all the way up to the open attic space. Hot air cannot get out unless there is cool air coming in to replace it. The cool air cannot get in if it is blocked by baffles or insulation.
Just done something similar. Use a bucket of hot water, a couple of glugs of Chlorox bleach, and a small squirt of washing up liquid (all amounts approx). Use a long handled softish brush, dunk it in the bucket, then generously brush the liquid along the soffit panels and gutter face.
Although it's safe to pressure wash soffits, there are few important things to remember: One key point to keep in mind is the water pressure. A high-pressure water blasting can be dangerous for your attic. Water may flow into your attic causing a greater havoc.
Fiber Cement Soffit
Fiber cement is a composite material made from sand, cement and cellulose fibers. It's a popular choice for soffit due to its durability, low maintenance and resistance to rot, warping, termites and harsh weather conditions.
One of the easiest DIY methods for cleaning soffit vents is to use a vacuum cleaner and a long extension nozzle. Simply attach the nozzle to your vacuum and carefully insert it into the vent, being sure to clean out any dust, debris, or cobwebs that may have accumulated.
Soffits and fascia are frequently subject to precipitation, ice, and humidity. Water can collect on surfaces like roofs and gutters if there are leaks or insufficient drainage, which can foster the formation of mold.
Any siding and window installer will agree that wood soffit and fascia are vulnerable to moisture damage. Prolonged weather exposure can lead to wet or dry rot, crumbling, or warping. Low-quality vinyl soffit and fascia may show cracks or gaps resulting from physical damage or temperature fluctuations.
With a pressure washer
A pressure washer is the best tool for tackling stubborn dirt and stains on your fascias and soffits. You can also clean them from the ground, so there's no need to worry about standing on a ladder.
Soffit mold almost always appears with a dark grey or black coloration. The growth pattern tends towards radiating, circular spotting. Dimensionally, the mold growth is typically flat.

General preparation work, including soffit removal and disposal, costs between $1 and $4 per linear foot. However, standard removal prices should be part of your replacement cost estimate.
Typically, the cleaning action of rain will be adequate to wash the siding and soffit. However, vinyl siding and soffit should be washed periodically with a garden hose and clean water particularly in those areas not exposed directly to rain.
One of the most effective ways to clean a blocked soffit vent is to use compressed air blasts. A blast of air can easily blow out any debris in the vent. To use this cleaning method, you'll need to place a ladder and an air compressor in the area of the soffit vent.
The life expectancy of a soffit varies depending on the material and environmental factors. A well-maintained soffit can last 20 to 30 years. Regular inspections, cleaning, and timely repairs can help prolong its lifespan.
Prop up a ladder in a position where you can ideally reach both your soffit and fascia so you can clean them at the same time. Make sure that your ladder is in a stable position before climbing it. Get a large sponge and soak it in the bucket. Then scrub your soffit and fascia (in the direction of your house).
A simple mixture of water and vinegar can work wonders due to vinegar's natural acidity, which helps break down mold and acts as a natural disinfectant. DIY solutions provide a cost-effective and eco-friendly cleaning option for maintaining your soffits in top condition.
Ventilated attics are important to the lifespan and efficiency of your roof. Keeping the soffit vents clear is integral to the fresh-air circulating throughout the attic space! Using your leaf blower is a quick, easy, and safe remedy when your soffit vents are clogged.
However, using a pressure washer makes it easy to keep these hard-to-reach places looking great. Here, we'll cover which accessories can help, and we'll discuss a few tips for safe and effective pressure washing to get your soffits and gutters looking like new in no time.
Grime, filth, and pollutants are cleaned from soffits and fascias with a mild detergent, preventing soffit surface damage. Clean soffits and fascias carefully using a solution of mild detergent or dish soap, water, and bleach as soon as mold or mildew appears.
Most soffit and fascia panels will come with a guarantee for X amount of years (usually ten or more) but the exact time between replacements will depend on external conditions, the level of care they are subjected to, as well as the materials they are made from.
It costs around $10 per linear foot, or $2,500 total, to replace a soffit on an average-sized one-story home. However, costs can vary greatly by material, project complexity, and other factors.
