Kitchen faucets often become clogged by minerals in hard water; usually containing calcium and magnesium carbonates and soil particles.
This build-up of minerals causes corrosion on the faucet. 
The impure water can cause allergies and infections when used in the preparation of food, or when used for drinking.
It is thus important to know how to clean kitchen faucet properly. Frequent cleaning is also important to prevent corrosive buildup.
To begin to clean a kitchen faucet, we start with the interior, the faucet cartridge.

How to clean the kitchen faucet cartridge
It is located on the insides of the faucet and has a rocker switch that controls water pressure, and turning water on and off. Frequent or continued use of the faucet may result in a buildup of hard water mineral deposits causing it to start leaking water and stop turning properly.
First, turn off the water supply at the supply valves below the sink. Turn on the hot and cold water taps to drain out any extra water left. Block the sink with a piece of cloth to avoid small parts of the faucet falling in.
Place the towel around the faucet to absorb any water.
Remove caps or buttons on faucet handles and use the screwdriver on the screws. The make and models of faucets may differ, but they are attached similarly by screws. Remove any other parts.
Use the wrench to unscrew the cartridge assembly and put the bowl upside down over the faucet hole to direct water into the sink.
The extra pair of hands can turn on the water tap while you hold the bowl directing the water. Let it flow for about 3-5 seconds to remove any debris in the faucet.
Turn off the water and repeat for the other tap.
Clean the cartridges by placing them in the clean bucket of water, and begin opening and closing the cartridges by twisting them at their stems for maximum results.
Dry and reassemble them just as they were before, for them to work properly. Avoid over-tightening to prevent damage to the faucets.
Reopen water supply valves and taps to test if water is flowing perfectly. You are done with cartridges.

How to clean kitchen faucet
The faucet is the overall structure of the kitchen tap. It holds the other components. On this wear your gloves then use a wet cloth on the light stains then dry.
For hardened deposits, add a mild all-purpose cleaner. Avoid harsh cleaners such as bleach-based cleaners, heavy duty scrabs and sponges and industrial cleaners that contain hydrochloric acid, phosphoric acid or ammonia acids since they corrode the metal surface.
The water and white vinegar solution can also be used. Wrap a cloth soaked in the solution for 2-3 hours on the faucet then rinse off with clean water.
Note, don’t apply vinegar on iron due to corrosion. If unsure if the metal is iron, apply the solution on a small area and check if the metal surface dissolves before proceeding. You can now dry your faucet and test it out.
