Suitable for professionals and auto enthusiasts, this 16mm pocket-sized Battery Post and Terminal Cleaner boasts damage-resistant stainless steel bristles that won't flatten upon application. This promotes better electrical contact, removing corrosive build up more effectively. The top brush scours battery terminals; the bottom brush tackles the battery posts and can be accessed by removing the cap and twisting. A comfortable handle grip means you can work for prolonged periods while remaining in control. Cleaning terminals inside and outside couldn't be easier with this latest entry to the Draper range.
