Maxima Air Filter Cleaner – 17.1oz Aerosol | Case of 12 | Foam & Fabric Safe | CFC-Free | 79920

Maxima 79920 Air Filter Cleaner in the 17.1oz aerosol format, case of 12. Consistently ranked best in class for foam and fabric filter cleaning — a professional-strength, emulsion-type cleaner that removes heavy filter oil, grease, and contaminants without damaging filter media, foam cells, paper, or glue. CFC-free aerosol. Rinses clean with water. Ships fast across Canada and the US.

Emulsion Formula — How It Works

Maxima 79920 uses an emulsion-type cleaning formula rather than a solvent-based approach. The distinction matters for filter longevity:

• Emulsion vs solvent: Solvent-based cleaners dissolve oils and contaminants but can also attack foam cell walls, degrade glue joints at filter seams, and dry out filter media over repeated use. Maxima’s emulsion formula surrounds and suspends oil and grease particles in water-compatible micelles — allowing thorough contamination removal with a plain water rinse, without chemical aggression toward the filter structure.
• No caustic chemicals: No lye, no petroleum solvents, no caustic agents. Safe for long-term use on foam, cotton gauze, and paper-backed elements without accelerated media degradation.
• Water rinse: After application and dwell time, the emulsified contaminants rinse away with water — no solvent rinse required. Allow the filter to dry fully before re-oiling and reinstalling.

Foam and Fabric Filter Compatibility

Maxima 79920 is compatible across the two primary performance air filter types:

• Foam filters (motocross, ATV, off-road powersports): The dominant filter type in two-wheel and powersports applications — Twin Air, Uni Filter, and OEM foam elements. Foam filters require regular cleaning and re-oiling after each ride in dirty or muddy conditions. The 79920 aerosol format is particularly well-suited to foam filter service: spray on, work in, rinse off. Compatible with Maxima’s own filter oil products (sold separately) for a complete Maxima filter care system.
• Fabric / cotton gauze filters (automotive performance): K&N, aFe, Injen, AEM, Mishimoto, and similar oiled cotton gauze performance air filters used in automotive applications. Cotton gauze filters require periodic cleaning and re-oiling — the manufacturer’s recommended service interval is typically every 30,000–50,000 km for street use, more frequently in dusty environments or performance/track use. The Maxima 79920 is a compatible cleaner for these filters, though some manufacturers (K&N specifically) recommend their own branded cleaner for warranty purposes — confirm with your specific filter manufacturer if warranty is a consideration.

Aerosol Format — Application

The 17.1oz aerosol format (vs Maxima’s liquid cleaner concentrate) offers specific advantages in shop and field use:

• No dilution required: The aerosol is ready to use directly from the can. No measuring, no dilution, no separate container needed. Faster service for single-filter cleaning than a liquid concentrate setup.
• Directional spray: The aerosol nozzle allows precise application to specific areas of the filter — useful for spot cleaning heavily soiled sections or working cleaner into foam cells from the inside out.
• Shop convenience: A case of 12 supports a full shop season of filter service without repeated individual orders. At 17.1oz per can, each can services multiple filters before exhaustion — a case of 12 is appropriate for dealerships, service shops, or riding clubs servicing equipment across a full season.

CFC-Free Propellant

The 79920 uses a CFC-free (chlorofluorocarbon-free) aerosol propellant — compliant with North American environmental regulations. No ozone-depleting compounds.
