How to Clean an Air Filter with the Best Solvent

Cleaning an air filter is an important part of maintaining your vehicle's engine. The best way to do this is by using a mild solvent. There are a variety of products available from brands like Twin Air, Maxima, and spray cleaners specifically designed for foam filters. Mineral alcohols and solvents with high flash points can also be found at auto parts stores.

It is important to avoid solvents or kerosene, as these petroleum-based chemicals can damage or dissolve the filter materials. A great option for removing grease and heavy dirt is Simple Green multi-purpose cleaner. This product is gentle enough to clean air filters without damaging the filter material or other surfaces found on automotive equipment. If left uncleaned, these unwanted materials can be absorbed by the engine's air intake while driving, potentially damaging the pistons and blocking the carburetor.

K&N air filters only need to be thoroughly cleaned when parts of the screen are no longer visible, or approximately every 80,000 miles. Dry filters are usually made of foam, which blocks more particles than paper filters, but due to its density, it can inhibit air flow when it gets dirty. When cleaning an air filter, it is important to use a cleaner that will completely remove dirt and debris without using petroleum-based chemicals. This will ensure that your filter remains in good condition and that your engine runs smoothly. It is also important to follow the manufacturer's instructions for cleaning and replacing your air filter.
