About MucOff Ultra Corrosion Defense

LONG TERM PROTECTION! Introducing the ultimate protection for bike batteries and components. MucOff eBike Ultra Corrosion Defense uses state of the art anti-corrosion additives and inhibitors to provide class-leading protection against corrosion.


It even works on surfaces that already have rust and corrosion… it simply stops rust in its tracks! It drives out moisture and leaves a protective anti-corrosive layer on your bike’s frame, battery casing, battery terminals, metal parts, plastics and paintwork to keep the harmful effects of moisture at bay.


  • Penetrates and protects
  • Non-drying film
  • Rust preventing/anti-corrosion
  • Ideal for protecting battery terminals and casings
  • Resistant to hot, cold and salt water
  • Dissolves rust
  • Protection lasts up to 12 months*
  • Easy to apply! Comes with our ‘Genius Straw’
  • For use after washing to drive out excess water.



  • Shake can vigorously.
  • After washing your bike with Muc-Off Waterless Wash, apply Corrosion Defense to the frame, battery, battery terminals and any other metal parts to disperse remaining moisture.
  • Either spray directly on to the surface, or for a more even and thinner coating, apply with a cloth.
  • Wipe off any excess fluid or leave in place for a higher level of protection (but this may attract more dirt between washes).
  • Note: Mask braking surfaces before application with MucOff DIsc Brake Covers. Store in a cool, dry place. Do not apply to tire tread or braking surfaces.

*For extreme winter and muddy conditions, we recommend you wash your bike and reapply ‘Corrosion Defense’ more regularly.
