Permatex Battery Cleaner 5.75 oz Aerosol (Pack of 12) - Fast Corrosion

In this review the Permatex Battery Cleaner 5.75 oz aerosol is evaluated as a practical, workshop-ready cleaner for anyone who needs to remove corrosion quickly from storage batteries and their connections. The bottom line: this pack of 12 cans is best for technicians, fleet managers, and DIYers who value a fast, foaming cleaner that penetrates and lifts corrosion so you can rinse it away in minutes. The reviewer found it effective across automotive and marine batteries, easy to use, and especially helpful when a quick emergency clean is required.

Key Features

• Penetrates corrosion: The formula works into corroded posts and terminals to loosen buildup so it can be washed off without excessive scrubbing.
• Fast action: Stated to work in about three minutes, allowing a quick service or emergency cleanup with minimal downtime.
• Wide compatibility: Safe for use on storage batteries, cables, terminal connections and related attachments in emergency power systems.
• Foaming action: The product foams on contact to help lift dirt and grime away from metal surfaces for easier rinsing.
• Case pack supply: Sold in a 12-can pack, making it economical for shops, fleets, or anyone who services multiple batteries.

Who It's For

The cleaner is aimed at automotive and marine technicians, farm machinery mechanics, motorcycle owners, and facilities that maintain emergency power supply batteries. Anyone who needs a fast, no-fuss method to remove corrosion from terminals and cables will appreciate the foaming action and short dwell time.

It is less appropriate for someone who needs a dedicated battery conditioner or an anti-corrosion protectant; this product is a cleaner first and does not replace maintenance chemicals meant to prevent future corrosion. Also, if a spray can's actuator fails, individual cans may become unusable until replaced.

Pros & Cons

Pros

• Effectively loosens and removes corrosion and grime, restoring terminal appearance and contact.
• Quick three-minute dwell time speeds up routine checks and emergency cleaning tasks.

Cons

• Some users report occasional spray mechanism failure on individual cans, which can be frustrating in the field.
• It is a cleaner only and does not provide long-term anti-corrosion protection after use.
