Tips for cleaning radiator?

[powershift]

I drove over some brush and tiny parts of the brush ended up in my radiator (or whatever grill is in front). To clean it I used a soft paint brush, but the grill is not fully cleared. I searched around and the best idea found was using a chemical made for AC condensers in a house. Since the radiator is part plastic and aluminum, I wasn't sure if chemicals would be the right way to clean it but in concept if it eats the leaves then I wouldn't blow the leaves through with a light pressure hose and into the next set of cooling fins behind. Any ideas to clean the mess out?

If it were me, I’d try light compressed air from the other side blowing out with a soft vacuum cleaner brush to help pull it out. Done it many times.

Leaf blower from the engine side?

I use the pressure washer in the engine bay, on all my vehicles, quite frequently. Be mindful that those pressures can be quite large so don’t place the nozzle too close.

Google, "Radiator Genie". There's 2 types, pressured air and water. Lisle 88500 is a good one.
