Repeat the steps until the concrete splatters come off from the aluminum vinyl.

Alternatively, you can use a water-detergent mixture with a steel wool sponge. Though using this can leave strains on the aluminum siding, it can help you to take off the splatter more quickly. 

In one gallon of water, add a quarter cup of detergent and mix it. Now, apply the mixture to the splatter and keep it for at least one hour. After that take the steel wool sponge and rub it on the splatters. After finishing rubbing, take the pressure washer, set the pressure between 2500 to 3000 psi, and rinse off the entire splatter area.

3. Removal Process of Concrete Splatter from Wood Siding
