If your batteries and their connections are suffering from corrosion, Battery Corrosion Guard applied to your battery connections - whatever style you have (ie, post & clamp / side mount / stud) - will provide you the corrosion protection you expect.

Battery Corrosion Guard works best if you properly clean your connections with a cleaning agent (baking soda and water). Dry all connections before using the applicator brush to apply Battery Corrosion Guard.

Battery Corrosion Guard will dry to a rubber-like texture, sealing and carrying its own acid neutralizer to protect your connections. Battery Corrosion Guard will remain intact if undisturbed. With activities such as pressure washing under your vehicle hood or disconnecting your battery terminals, you will want to reapply Battery Corrosion Guard for lasting protection.

Do not use Battery Corrosion Guard in an unapproved manner. Battery Corrosion Guard is not known to be toxic. Not for human consumption. If swallowed or aspirated, immediately contact a physician. Eye contact, flush with water and contact a physician. Contains viscous hydrocarbons. Keep out of reach of children and pets.

This stuff is the bomb. Been using it for over 20 years. Smells bad, works good!

Corrosion problems with your battery terminals? Forget about it when using battery corrosion guard. I have been using this product for over 10 years on everything I own, from electric golf carts, lawn tractors, airplanes, motorcycles, cars and trucks. THIS STUFF WORKS. It is messy to work with once it is applied but, the lack of corrosion problems is well worth it.
