Outdoor Speaker Corrosion

If you have outdoor speakers either on your back lawn, boat, or other outdoor atmosphere, you most likely
have witnessed corrosion problems.

Prevent outdoor speaker corrosion:

Apply Corrosion Block to the outdoor speaker in several places. Corrosion Block is entirely safe to rubbers, plastics, and other materials that your speakers may contain (especially the surrounds, spider, and basket).

We suggest you treat these especially:

- Speaker terminals
- post terminals (on speaker enclosures)
- Voice coils
- mounting screws for grills
