To properly clean and maintain Aluminum Air Vent Covers, you can refer to the following steps and methods:
Cleaning steps:
Prepare tools:
Soft cloth or sponge
Mild detergent (such as soapy water or neutral detergent)

Preliminary cleaning:
Use a broom or soft cloth to gently remove large particles of debris such as dust, leaves, etc. from the vent cover.
