This is already enough to get rid of rust. On outdoor surfaces like concrete driveways, walks, patios, and garage floors, there’s no need to apply harsh and hazardous chemicals.

High-pressure water, on the other hand, can harm more fragile surfaces like vinyl sidings, wood decks, brick walls, and asphalt shingles. Soft washing is a more gentle cleaning method that will be required.

Instead of using only high-pressure water to eliminate rust, gentle washing uses a combination of low-pressure water and environmentally friendly, biodegradable cleaning chemicals.

Here’s how to remove rust from your house using pressure and gentle washing.

1. Set Up the Environment

When exposed to high-pressure water, nearby plants, glass windows, furniture, and other things may be harmed. Before you start pressure washing, cover these areas with a tarp.

2. Put on your protective gear

Although it may not appear so if you are new to pressure washing, the stream of water that comes out of a pressure washer is powerful enough to cause significant bodily injury and accidents. When utilizing a pressure washer, it’s vital to use safety goggles, a face mask or respirator, waterproof gloves, and steel-toe boots.

3. Make Use of the Appropriate Tools

The type of pressure washer you use will be determined by the surface you’re cleaning. It is not recommended that you utilize the same setting for all of your external surfaces. In general, however, a pressure washer with a PSI of 2,000 to 3,000 is required. If you use anything less, you might not be able to get rid of rust on your property.

You should also consider which nozzle to utilize. When compared to a larger, 25-degree nozzle, a 15-degree nozzle (yellow tip) will discharge a more forceful jet of water (green tip).

4. Conduct a patch test

Even if you’re working with concrete that can withstand hammering, continue with caution. Perform a patch test before you go all out with the pressure washing. This is to guarantee that the water stream is not too fast for the surface to manage.

5. Eliminate rust with pressure washing

If you’re ready, apply pressure to your external surfaces to eliminate rust. To get the greatest results, keep a six-foot gap between you and the surface and aim your pressure washer wand squarely at it. To avoid streaking, start from the top and work your way down, then left to right.

6. Apply a layer of protective sealant.

Consider adding a sealer to your external surfaces once the rust has been removed. This will coat your surfaces in a protective coating, making them more resistant to rust in the future. You’ll be able to make your external surfaces last longer.


You can remove rust off metal with a pressure washer with a minimum of 3000 PSI and a narrow-angle nozzle. The powerful water jet can eliminate rust and save you time sanding and scraping. When cleaning up an old patio or deck furniture, this is very helpful.
