Rust is an inevitable issue that occurs when metal surfaces are exposed to air and moisture over extended periods. It often manifests as an orangey-red stain on metal surfaces, which can become noticeable even through layers of paint. While rust may initially seem like a minor aesthetic problem, it can lead to significant structural issues if left untreated. Rust corrodes metal, weakening its integrity over time, which can result in damage to various parts of your home, such as metal fences, outdoor furniture, garage doors, or even structural supports. Therefore, addressing rust promptly is essential to avoid long-term damage.
Pressure washing is one of the most effective methods for removing rust, helping restore the appearance of metal surfaces while preventing further corrosion. However, this process involves more than simply blasting water at high pressure. When done correctly, pressure washing can remove rust, but it’s crucial to follow proper techniques to avoid causing additional damage.
Removing Rust with Pressure Washing: How It’s Done
Pressure washing works by using a combination of high-pressure water and specialized cleaning solutions to break down rust. Rust removal from surfaces like concrete, metal, or painted areas requires careful preparation and proper technique. A pressure washer allows you to target specific areas of rust buildup, gradually wearing down the rust without damaging the underlying surface.
However, different surfaces require different pressure settings. For instance, when dealing with rust on concrete, you may need a higher pressure setting than on painted metal, where too much pressure could strip the paint or damage the metal itself. For rust that has deeply penetrated the surface, a chemical rust remover might be used in conjunction with pressure washing to ensure all traces of rust are eliminated.
Before the pressure washing process begins, the surrounding areas must be prepped. This involves removing any loose debris or items from the area, such as furniture or decorations, that could be damaged by the high-pressure water. Next, a rust-dissolving solution is often applied to help loosen the rust, making it easier to remove. Once the solution has had time to work, the pressure washer can be used to rinse away the rust and cleaning solution, leaving behind a clean surface.
“Rust forms when iron or steel comes into contact with moisture and oxygen, resulting in the oxidation process. By directing a forceful jet of water onto the rusted area, the pressure washer can break down and wash away the rust, restoring the surface to its former glory.”

For particularly stubborn rust, multiple passes with the pressure washer may be required, or the use of a rust remover spray might be needed. It’s important to approach rust removal carefully, as too much pressure or incorrect settings can cause more harm than good.

The Dangers of Attempting a Do-It-Yourself Power Wash
While pressure washing might seem like a simple and efficient solution for rust removal, it’s not a task to take lightly, especially for those with little to no experience. Many homeowners who attempt to remove rust on their own with a pressure washer quickly realize that it’s more complex than they initially thought.
DIY pressure washing can be risky for the following reasons.
- Choosing the Wrong Settings and Nozzle — It takes extensive training to learn the proper settings for the different materials the power washer encounters. If you don’t get the setting right or choose the wrong nozzle, you may cause extensive damage to the rusted area and the surrounding area that had been in fine shape. The wrong settings can also make the power washer harder to control, leading to substandard results.
- Failing to Secure the Jobsite — When working around the house, the do-it-yourselfer will tend to be pretty lax about setting up a secure job site. After all, what could go wrong? Quite a bit could and probably will go wrong if you proceed without setting up a safe and secure work area. The force of the water being expelled from the power washer is enough to break glass, uproot plants, and knock over furniture and poses a very real risk to pets and small children. The pros will take the time to ensure the work can be conducted safely.
- Being Financially Responsible for Mistakes — If you remove rust using a power washer, then any damage you do to the house will be your responsibility. Likewise, if someone should wander onto the work site and incur an injury, you will be responsible for their medical bills. When you hire the pros at Majestic Windows & Exterior Cleaning, you can rest easy knowing we are fully insured. In the extremely unlikely event, something should get damaged, or someone should get hurt, you are shielded from financial responsibility.
