What is not recommended for cleaning foam filters?

Washing or cleaning foam filters in gasoline is not recommended because gasoline can break down the foam material, damaging the filter and reducing its effectiveness. Additionally, gasoline is a highly flammable substance that poses significant safety risks when used as a cleaning agent. Proper maintenance of foam filters typically involves using milder cleaning methods that preserve the integrity of the foam, such as washing them with water and soap, which safely removes dirt and debris without compromising the filter's structure. Air drying is also a common practice, as it allows the filter to dry thoroughly without using heat sources that could potentially damage the material.
