Many homes in New Jersey have Dryvit siding, a synthetic stucco product. While Dryvit is purported to be easy to clean, it can get develop reddish-looking stains. Whether it’s a real stucco product or synthetic Dryvit, getting a tough stain out isn’t easy and it can cause damage.
Red stains can be very unsightly, especially when it drips down the side of the house or makes orange stains from the ground up. Unfortunately, they can be very difficult to remove. It is all too easy to damage the Dryvit when trying to remove stains, so care must be taken.
Before learning how to safely clean Dryvit siding, let our New Jersey power washing pros help you figure out what causes those reddish stains in the first place. Then, it will be easier for you to determine the best way to remove them safely.
Inspecting Your Dryvit For Rust Stains
If red stains are dripping down the siding from the roof line, chimney, gutters, or any metal protrusion on the roof or side of the house, it is likely a rust stain. Metal balconies, roof flashing, rusty gutters, and even metal screws can cause red stains. Just like concrete, stucco can get stained a reddish color from rusting metal.
However, sometimes the red stains are caused by the rainwater and soil, not rust. Soil and water have iron sediments in them naturally, so rainfall can create the rust stains on your Dryvit.
Orange Stains On Dryvit Near Ground level
The orange stains could be caused by something much easier to clean. If the stucco surface is stained orange from the ground level upward, the stain may have come from the soil. Clay soil can make orange stains the side of a house when it rains and the drops splash the ground or the water pools around the foundation.
Cleaning Rust Stains From Dryvit Siding
Whether it’s Dryvit siding or stucco, you don’t want to damage the material during cleaning. Red stains are hard to remove if they are rust stains.
One of the best tips we can give you is not to use harsh chemicals or stiff wire-bristled brushes to clean your Dryvit stains. Once the stucco material gets damaged, it will let moisture seep in behind it. The next thing you know, the Dryvit will start to peel off.
Your safest bet is to hire a professional power washing company who knows how to remove rust stains from Dryvit. If that is not an option, start by using a soft-bristle brush dipped in 1 gallon of warm (not hot) water and 1 cup of liquid detergent.
If that does not completely remove the stains, a mild pressurized water clean and rinse may be in order. Pressure washing with no more than 600 psi and using cold water may be all that’s needed. Be sure to hold the fan-tip nozzle at a 45° angle from the wall and keep it at least 2 feet from the surface.
Power washing professionals will treat the rust stain with a commercial-grade stain remover if necessary. If you plan to treat the stain yourself, make sure to follow the Dryvit manufacturer’s suggestions before throwing bleach or muriatic acid on it. Otherwise, you could void the warranty by causing damage.Call our team at The Roof Wizard today!
