When learning how to clean aluminum gutters and soffits, we usually follow these simple steps:

1. Soak Your Soffits

Whenever you pressure wash anything, whether it’s your home’s soffits, your home exterior, your car, or your van, you need to do a preliminary soak. This is important to do this step because it allows you to loosen the dirt. This step also allows you to take out the dry and flaky debris. 

2. Apply Some Detergent

The next thing that you should do is apply some detergent with a low-pressure nozzle. Therefore, take out the detergent that you want to use and put it in the detergent tank. Test to see if the detergent comes out of the nozzle. If it does, start spraying the detergent on your soffits. You can leave the detergent on your aluminum soffits for around 5 minutes to let the soap settle. 

3. Rinse the Detergent

After the 5 minutes are over, switch to a mid-level pressure nozzle and rinse the detergent away. You’ll notice that as you rinse the detergent away, you’ll also wash away the sticky dirt and grime. Detergent helps loosen up the thick dirt, making the cleaning job easier. 

4. Aim for the Inside

Once you’ve cleaned out the outer part, you now have to move to the inner portion. To do this, use a curved wand. This allows you to aim for the inside area since the water will also curve. Do not try to elevate yourself with a ladder or a chair. The power of a pressure washer is enough to push you off and cause some serious injuries. 

5. Do a Final Rinse

After you’ve cleaned the inner area of your soffit and gutters, just do one final rinse on the inner and outer portions. This is just to make sure that no dirt was left behind after the previous steps. Just keep it quick though as you don’t want to pressure wash for too long. Prolonged pressure washing may cause some damage to your gutters. Once you’re done with the final rinse, you can start painting or polishing your aluminum soffits if you like. 


What we’ve shown you above is the easy way to clean aluminum soffit. Now that you know how to clean aluminum soffits properly, you don’t have to worry about whether it’s safe or not. As long as you follow all the steps that we’ve mentioned above, then you should have absolutely no problem. 

Just make sure that you keep safe when using your pressure washer. Wear all the necessary safety gear and also don’t point the pressure washer anywhere except the soffits. Don’t forget to also read all the precautionary measures listed on your pressure washer’s user manual. 

With all that, you’re now set to clean your aluminum soffits! Hope you learn something from this article!
