They aren't always made of light materials. For example a 57 Desota, very heavy hood. Depends on the manufacturer, the hood is usually made out of the same material as the rest of the car.
Every car ever made is just a cable to open the hood. Use your key to unlock the door and pull the cable marked "hood".

Steel, aluminum, fiberglass, or carbon fiber depending on the vehicle the hood is installed on. Most are made of steel.

Local car dealerships and auto detail companies may provide under car hood cleaning. For general top of the car hood cleaning, visit a local car wash.

One way to tell if it is a big-block car is if the car has a 'Power Blister' hood, which is a funnel shaped hood bulge on the hood .
