Confidently clean up spilled bases from alkaline batteries with this loose-absorbent neutralizer that changes colors, so you know when it is safe to handle. The color indicator in the absorbent identifies the base in the spill and monitors the progression of the neutralization: BLUE: Highly caustic (normally only seen with the most concentrated caustics) YELLOW: Slightly caustic ORANGE: Non-caustic. The neutralizer granules soak and trap the spilled battery bases for safe battery cleanup. The loose absorbent comes in a granular form which makes it easy to clean up on uneven or cracked surfaces. The base neutralizer is ideal to keep near your alkaline battery storage locations for quick response cleanup. The container is resealable so you can use as much as you need on each spill.
