Based on the provided information, the reference discusses using brake cleaner on the air box, not directly on the air filter itself.
While the question asks about using brake cleaner on the air filter, the specific reference provided details its use for cleaning the air box.
What the Reference Says About Cleaning the Air Box
The reference explicitly states:
We find brake clean works really well to remove the old air filter oil, grease and dirt from the air box.
It suggests this is an effective method for cleaning out the housing that contains the air filter. A practical tip mentioned is to stuff a clean rag inside the air boot during cleaning to prevent debris from entering the engine.
Distinction: Air Filter vs. Air Box
It is important to distinguish between the air filter and the air box:
- Air Filter: This is the component that actually traps dirt and debris from the incoming air before it reaches the engine. Filters are typically made of paper, foam, or cotton gauze and are often treated with oil (especially foam or cotton filters).
- Air Box: This is the housing or container that holds the air filter. It connects the external air intake to the engine's intake manifold.
The reference provides a method for cleaning the air box, which can accumulate oil, grease, and dirt that comes off or bypasses the filter. It does not recommend using brake cleaner directly on the porous material of the air filter itself.
Cleaning procedures for air filters typically involve specific filter cleaners, washing, and re-oiling (for reusable filters) or simply replacement (for paper filters).
Therefore, while brake cleaner is noted as effective for cleaning the air box according to the reference, this information does not support its use directly on the air filter element.
