Muc-Off Air Filter Cleaner 1L — Foam Motorcycle Air Filter Cleaner, Solvent-Free Biodegradable Formula

Muc-Off Air Filter Cleaner 1L is a biodegradable, solvent-free cleaner formulated to remove oil, grease and heavy grime from foam motorcycle air filters without harming the foam or glue.

Built for off‑road riders and workshop technicians, this concentrated 1‑litre formula breaks down contaminant build‑up so you can restore airflow and prolong filter life. It’s designed to be rinsed away with water, safe on foam when used as directed, and compatible with subsequent application of air filter oil. Available in larger sizes for frequent servicing, this product is part of Muc‑Off’s high‑performance Off‑Road range.

How does this cleaner remove oil and grime without damaging foam?

The formula uses active, non‑solvent ingredients that dissolve oils and loosen embedded dirt while being gentle on foam structure and adhesive points. It avoids harsh solvents that can degrade foam polymers or unstick filter glue.

• Solvent‑free chemistry designed for foam integrity.
• Rapidly breaks down heavy oils and grease for easier rinsing.
• Rinses clean with warm then cold water—no residue left behind.

What’s the correct way to clean a foam air filter with this product?

Remove the filter, shake off loose debris, then soak it briefly in a container with enough cleaner to cover the element. Massage while wearing gloves, rinse thoroughly, and let it dry fully before oiling and refitting.

• Soak filter 1–2 minutes; massage gently—do not twist.
• Rinse: warm water soak then thorough cold-water flush.
• Dry completely before applying Muc‑Off Air Filter Oil and reinstalling.

Can this cleaner be used on all motorcycles and off‑road vehicles?

Yes—this cleaner was developed for foam air filters commonly used on motocross, enduro, trail bikes, ATVs and other off‑road machines. It suits both occasional users and professionals who service multiple filters.

• Suitable for motocross, MX, dirt bikes, ATVs and similar vehicles.
• Available in 1L for home use and 5L for frequent servicing or shops.
• Repeat application for stubborn oil or grease until filter is clean.

Are there any safety or surface‑care cautions I should know?

Although biodegradable and solvent‑free, the cleaner can affect sensitive painted surfaces if allowed to dry there; always test on a small area first and avoid contact with non‑porous finishes. Use gloves and work in a ventilated area.

• Do not let product dry on painted or delicate surfaces.
• Always test on an inconspicuous area before full treatment.
• Wear workshop gloves and follow local disposal guidance for rinse water.

Who is this for? Riders, mechanics and race teams who regularly service foam air filters and need a powerful yet foam‑friendly cleaner will benefit most from the Muc‑Off Air Filter Cleaner 1L. It’s ideal if you want an effective, easy‑rinsing product that removes oil and grime without aggressive solvents, and it scales from occasional home maintenance to workshop use when paired with the 5L option.
