Excellent battery cleaner! It neutralized the corrosion on my car battery within seconds. The color-changing formula is very helpful to ensure all acid is gone. The spray nozzle provides good pressure to get into tight spots. High quality product from a trusted brand like NOCO. Would definitely buy again.
