What causes carbon build up on cylinders?

Carbon buildup occurs as the fuel burns in your car. Older gasoline engines relied on fuel injectors to spray fuel into the air intake manifold where the air and fuel would mix. This mixture then moved through the engine cylinders at timed intervals and to the spark plugs where it ignited and boomed.

Can carbon deposits inside the cylinder affect the engine’s power?

One by-product of combustion is carbon, the black soot that can collect and harden on the cylinder head, cylinder wall, piston and valves. Carbon deposits in the combustion chamber can affect engine performance, resulting in higher oil consumption, engine knocking or overheating.

How do I get rid of carbon build up in my grill?

Water, a mild dish detergent (like Dawn), and a clean sponge will help safely clean off any remaining residue and carbon from any components. Just make sure to thoroughly rinse and dry them before cooking again.
