Product Information

Full details

The Muc-Off MO-94 Multi-Use Spray is an essential maintenance tool for cyclists, motorcyclists, and car owners looking to preserve their mechanical components. This versatile spray excels at penetrating moisture, lubricating moving parts, and preventing rust and corrosion with a protective, biodegradable film. While it is highly effective for loosening seized bolts and silencing squeaks, users must exercise caution to never apply the spray to tire treads or braking surfaces, as its lubricating properties pose a significant safety risk in those areas.

FAQs

Can I use MO-94 on my bicycle chain?

While it provides some lubrication, it is best used as a protector or for freeing seized parts. For heavy-duty chain lubrication, consider using a dedicated Muc-Off chain lube.

Is it safe for carbon fiber frames?

Yes, the formula is safe to use on carbon fiber and most painted finishes.

How long does the protective film last?

The duration of the protection depends on weather conditions and exposure to the elements. For high-wear areas, reapply after every few rides or washes.

Does it contain silicone?

No, the formula is designed to be versatile without the use of heavy silicone residues.

What should I do if I get it on my brake rotors?

Immediately clean the rotors with a high-quality brake cleaner to remove the lubricant. Do not ride the vehicle until the braking performance is restored.

Troubleshooting

The spray nozzle is clogged or not misting properly

Remove the nozzle and rinse it under warm water, or use a small needle to clear any dried debris from the tip.

Product leaves an oily residue on unintended surfaces

Wipe away overspray immediately with a clean, dry microfiber cloth. If it has already dried, use a degreaser to remove the film.

The spray is not effectively loosening a seized bolt

Apply a generous amount to the thread, tap the bolt head gently with a hammer to help the fluid penetrate, and allow it to sit for at least 15 minutes before trying again.

Pros and Cons

Pros

  • Versatile use across bikes, motorcycles, cars, and household items
  • Effectively frees up seized or rusted mechanical parts
  • Provides a protective layer that helps resist future dirt buildup
  • Biodegradable formula is safer for the environment
  • Large 750ml bottle is ideal for high-frequency maintenance

Cons

  • Not suitable for use on braking surfaces or tire treads
  • Requires careful application to avoid overspray on sensitive areas
  • Large size may be bulky for emergency kits compared to smaller canisters

Setup, Compatibility & Care

MO-94 is compatible with most metal surfaces, plastics, and painted finishes found on bicycles and motor vehicles. To use:

  1. Ensure the area to be treated is free of heavy debris or mud.
  2. Shake the can well before use.
  3. Spray the area lightly from a distance of 15-20cm.
  4. Allow the product to dry completely; do not wipe it off, as this removes the protective layer.

Important Safety Warning: Never apply this product to tire treads, bicycle brake discs, brake pads, or rim braking surfaces. The resulting lubrication can lead to a complete loss of traction or braking power. If the product accidentally contacts these surfaces, clean them immediately with a dedicated brake cleaner.
